  One aspect of the present invention is capable of acquiring and notifying distribution information including type information of a traffic monitoring activity carried out to promote traffic safety and position information of a monitoring position, and is another aspect of the present invention. The notification terminal that constitutes the driving support information distribution system is provided.

One embodiment of the present invention is a program for causing a computer to execute,
Another aspect of the present invention is a server program for realizing a function of a server device constituting the driving support information distribution system according to another aspect of the present invention.

One embodiment of the present invention is a program for causing a computer to execute,
Another aspect of the present invention is a posting program for realizing the function of the posting terminal.

One embodiment of the present invention is a program for causing a computer to execute,
According to another embodiment of the present invention, there is provided a notifying program for realizing a function of the notifying terminal.

  By using the posting terminal according to the present invention, it is possible to generate post information including type information indicating the type of traffic monitoring activity performed to promote traffic safety, and post information including position information indicating a monitoring position. You can post. The server device generates distribution information including type information and position information on the traffic monitoring activity by integrating a plurality of pieces of posting information sharing the same traffic monitoring activity. The notification terminal can notify the distribution information distributed from the server device.

  The distribution information can be, for example, highly real-time information generated based on the post information, but the accuracy of the post information varies, and there may be correct information or incorrect information. If a plurality of pieces of posted information that are not determined to be true or false are delivered as they are, there is a possibility that confusion as to which information may be believed on the notification terminal side may occur. In particular, when the notification terminal is installed in the vehicle, or when a portable notification terminal is brought into the vehicle, for example, if such posted information is distributed as it is while the driver is driving, it may hinder driving. Could be.

  On the other hand, the distribution information in the present invention may be, for example, information whose accuracy is improved by integrating a plurality of pieces of posted information. In the distribution information, for example, real-time properties based on post information and accuracy improved by information integration are compatible. Distribution information that achieves both real-time performance and accuracy can be useful information for the driver.

  INDUSTRIAL APPLICABILITY As described above, the present invention is a system that provides information on traffic monitoring activities such as traffic control and check-up to assist driving, and is useful for realizing a driving support system with improved real-time performance. .

The traffic monitoring activities targeted by the posted information in the present invention include traffic control such as speed control, parking prohibition control, and seat belt control, and checks such as drinking check and seat belt check.
The server device according to the present invention may have both of a function of receiving the posted information and a function of transmitting the distribution information, or a server that receives the posted information, and a server that receives the distribution information. May be connected to a dedicated server, a dedicated communication line, a public communication line, or the like.

  The server device in the driving support system according to a preferred aspect of the present invention is configured such that a time related to the posting of the posted information is within a predetermined time, and a plurality of pieces of posted information whose monitoring positions belong to a predetermined range are the same. Treated as posted information for traffic monitoring activities.

  The time related to the posting of the posted information may be a time when the posted information is generated, a time when the posted information is posted, a time when a traffic monitoring activity related to the posted information is witnessed, or the like. By combining the temporal proximity that the time related to the posting is within a predetermined time and the spatial proximity of whether the monitoring position belongs to a predetermined range, the same traffic monitoring activity can be performed. The target posted information can be extracted with high certainty, and highly accurate distribution information can be generated. The time at which the posted information was generated and the time at which the target traffic monitoring activity was witnessed need to be specified on the posting terminal side. Regarding the posted time, the time at which the posted information was transmitted may be specified on the posting terminal side, or the time at which the posted information was received may be specified on the server device side. When the time specified on the posting terminal side is used on the server device side, it is preferable to include time information indicating the time in the posting information.

The position information indicating the monitoring position in the driving system according to a preferred aspect of the present invention is information that can specify the traveling direction of the vehicle targeted for the traffic monitoring activity, in addition to the monitoring position where the traffic monitoring activity is being performed. is there.
Except for one-way roads, roads on which vehicles can travel in both opposite directions are generally used. Some of the traffic monitoring activities performed on roads include only one traveling direction, for example, road speed control or check. If the distribution information can specify the traveling direction targeted by the traffic monitoring activity, it becomes more useful for a driver driving on a road on which the traffic monitoring activity is performed. Because the degree of importance of the distribution information is completely different depending on whether the driver is traveling in the traveling direction targeted by the traffic monitoring activity or the driver traveling in the opposite direction. is there.

The server device in the driving assistance system according to a preferred aspect of the present invention evaluates the accuracy, which is the degree of certainty of the posted information, and according to the certainty in generating the distribution information by integrating a plurality of pieces of posted information. To change the handling of each posted information.
Examples of handling of posted information according to the accuracy include the following. For example, the distribution information is generated using only the post information having a certain accuracy or higher. For example, post information that does not satisfy a certain degree of accuracy is handled as one piece of post information when a plurality of pieces of similar post information are posted. For example, one post of the same type within a radius of 100 m is one post.

The server device in the driving assistance system according to a preferred aspect of the present invention evaluates the accuracy of the corresponding posted information according to whether or not the poster of the posted information is a identifiable person and the posted result of the poster. I do.
Generally, it is possible to estimate that posted information from a specific person is more accurate than posted information from an unspecified person. For a specific contributor, points such as the number of times correct post information has been posted may be converted into points, and the points may be used when evaluating the accuracy of the post information by the specific poster.

As the posting terminal in the driving gaze system according to a preferred aspect of the present invention, various types of application programs including a dedicated machine in which the posting information posting function is incorporated in advance, and an application program for incorporating the posting information posting function There is a general-purpose machine that can be selected and installed by the user side,
The server device evaluates the accuracy of the posted information according to whether the posted information is information posted from a dedicated device or information posted from a general-purpose device.

  The introduction cost on the user side for using the posting function and the degree of expectation for the distribution information differ between the dedicated machine and the general-purpose machine. For example, when the application program of the general-purpose machine is free software or the like, there is a possibility that a user who is not interested in the distribution information may contribute by mischief. On the other hand, considering that the dedicated machine has been purchased, it can be estimated that the poster from the dedicated machine has a sense of expectation for the distribution information. For this reason, for example, when the degree of detail or the quality of information of the posted information itself is substantially the same, it is preferable to evaluate the accuracy of the posted information by the dedicated machine higher than the posted information by the general-purpose machine. good.

The server device in the driving support system according to a preferred aspect of the present invention evaluates the accuracy of the posted information with reference to information on a past traffic monitoring activity.
For example, if posted information on speed control is posted at a location where speed control is frequently performed by mobile orvis, the accuracy of the posted information can be highly evaluated. On the other hand, if posted information on speed control is posted for a location where speed control by mobile orvis has never been performed, first, the accuracy of the posted information is evaluated low, while similar posted information It is also good to review the evaluation of the accuracy of the first posted information when the is posted twice.
The information on the implementation status of the past traffic monitoring activity may be, for example, an execution history of the past traffic monitoring activity, or may be existing traffic information stored in advance regarding the traffic monitoring activity. In particular, existing traffic information that has already been accumulated by on-vehicle devices such as radar detectors without relying on posted information may be used as information on the status of past traffic monitoring activities. Further, information obtained by adding past posted information to the already accumulated traffic information may be used as "information on the past traffic monitoring activity implementation status".

In the server device in the driving system according to a preferred aspect of the present invention, the handling of the posted information is performed in accordance with whether the posting of the posted information is received before or after the delivery of the corresponding traffic monitoring activity. Are different.
Before distribution, for all contributors, the traffic monitoring activity to be posted appears unexpectedly, and it is necessary to determine the type and the like in a short time before passing. There is a tendency that a registration operation or the like of a point of the traffic monitoring activity is performed after passing the point, and the point to be actually registered may be shifted forward in the traveling direction from the actual point. On the other hand, after the distribution, it is known in advance that the traffic monitoring activity of the type related to the distribution information is being performed. There is a tendency for the accuracy of the determination of whether or not to be high. In addition, since a person is very interested in whether or not a traffic monitoring activity is actually being performed at the point related to the distribution information, he or she approaches the point, so that the registered point is likely to be perfect for the actual point. . Alternatively, a quick contributor may be closer to the actual point. If the post information after distribution of the distribution information is handled in consideration of such circumstances, the accuracy of the distribution information including the positional accuracy can be improved.

The server device in the driving assistance system according to a preferred aspect of the present invention determines whether or not to distribute the distribution information and a distribution time for continuing the distribution according to the type of the traffic monitoring activity.
For example, traffic monitoring activities such as speed control such as mobile orvis are generally known for their duration, and do not continue for 24 hours. It is good to determine the distribution time of distribution information based on such knowledge.
On the other hand, for information relating to fixed speed control, N system, and the like, there is a tendency that accuracy closer to 100% than real-time accuracy is required. Therefore, rather than immediately distributing the distribution information in response to reception of post information for fixed speed control and N system, etc., after the staff of the system operator goes to the site and visually checks it, It may be provided to the user as confirmed information.

The posting terminal in the driving support system according to a preferred aspect of the present invention can post cancellation information indicating that the traffic monitoring activity corresponding to the distribution information has not been performed,
The server device evaluates the accuracy of the posted cancellation information, and determines whether or not to end distribution of the corresponding distribution information according to the accuracy.
If the posting of the cancellation information is accepted, the distribution can be completed as soon as possible after the corresponding traffic monitoring activity is completed. It is possible to suppress a situation in which the corresponding distribution information continues to be distributed in a short time, even though the target traffic monitoring activity is not performed. Further, the cancellation information is also useful for stopping distribution of erroneous distribution information based on fake posting information at an early stage, or for giving a negative evaluation to a poster of fake posting information.

The server device in the driving assistance system according to a preferred aspect of the present invention, when receiving distribution of the cancellation information and then distributing distribution information on a corresponding traffic monitoring activity, notifies that the cancellation information has been posted. Is included in the distribution information.
On the user side, when determining the accuracy of the distribution information, the determination can be made in consideration of whether or not the cancellation information is posted. The fact that the corresponding traffic monitoring activities are not performed is the biggest factor that impairs the user's confidence in the distribution information. When distributing the distribution information, if the user is notified that the cancellation information has been posted, the loss of the user's confidence in the distribution information will be minimized even if the corresponding traffic monitoring activity is not implemented. Can be controlled close to Note that the information indicating that the cancellation information has been posted may be, for example, information indicating whether or not the cancellation information is posted in the integrated posting information, and whether or not the posting is performed. In particular, the information may be information indicating the number of posts of cancellation information. For example, it is preferable to distribute the number of posts of integrated post information and the number of posts of cancellation information among the number of posts.

A posting terminal according to a preferred aspect of the present invention includes means for generating posting information having a different degree of detail of the type information according to a knowledge level regarding a traffic monitoring activity on a user side.
For example, when the traffic monitoring activity of the target is speed control, the types thereof include a mouse trap, a mobile orbit, and a tracking. Further, for mobile orbis, for example, there are types such as a radar type, a stealth type, and a photoelectric tube type. Any user who has a deep interest in traffic monitoring activities such as speed control and can recognize the type of equipment or device at a glance can post detailed information. On the other hand, a user who can recognize that it is a traffic surveillance activity related to speeding violations, but has little knowledge of speed measurement, requesting detailed information at the time of posting may be difficult to post itself and may hesitate to post. high. Therefore, users who have knowledge of traffic monitoring activities can generate detailed posting information, while those who do not can simply post posting information with detailed level of speed control, Can be promoted. If the number of posted information as an information source increases, the real-timeness and accuracy of distribution information can be improved.

A posting terminal according to a preferred aspect of the present invention is capable of acquiring a current position, and combining the type information generated by an operation on the user side with position information based on the obtained current position, to thereby provide the posted information. Generate
In this case, the accuracy of the position information included in the posted information can be improved. As a configuration capable of acquiring the current position, for example, there is a configuration having a positioning function by GPS, a configuration of acquiring information on the current position from an external terminal having a GPS function, and the like.

A posting terminal according to a preferred aspect of the present invention includes a first terminal capable of generating the posted information in response to an operation on a user side, and acquiring the posted information from the first terminal and directing the first terminal to the server device. And a second terminal for transmission.
The first terminal is a terminal capable of acquiring a current position and displaying a code image recording the post information,
The second terminal may be a terminal capable of capturing a code image displayed by the first terminal and reading recorded post information.
As the second terminal, a mobile terminal such as a smartphone (multifunctional mobile terminal) having a camera function or a game machine having a camera function and a communication function can be used. The first terminal only needs to display the code image in which the posted information is recorded. Such a first terminal can be sufficiently realized by a hardware configuration of an existing radar detector having a GPS function, in addition to a display screen of about 3 to 4 inches.

The posting terminal according to a preferred aspect of the present invention can display a map of a predetermined area including the point of interest, and can register the point of interest as a specific point by a user operation,
The post information is generated by associating the type of the traffic monitoring activity selected by the user's operation with the position information indicating the specific point registered in advance.
On the displayed map, a specific point can be registered with high positional accuracy. Post information generated through such registration of a specific point is information with high positional accuracy and high accuracy.

A posting terminal according to a preferred aspect of the present invention is capable of acquiring a current position, and the current position is set as the point of interest.
In this case, when passing the point of the traffic monitoring activity, that is, when the current position is located in the immediate vicinity of the point, by performing the registration operation of the specific point, the point of the traffic monitoring activity can be easily and simply located. You can register with high accuracy.

A reporting terminal according to a preferred aspect of the present invention is capable of acquiring a current position and a current time, and selects which of the acquired distribution information to be reported according to the current position and the current time.
In this case, appropriate distribution information according to the driving situation can be reported. For example, even if the distribution information of the traffic monitoring activity at a point that is far from the current position of the user and for which it is not known whether or not to go is notified, the information has low value for the user. On the other hand, the distribution information on the traffic monitoring activity that is being carried out near the current position of the user is valuable information for the user, and thus it is good to report the information. Further, a navigation function may be provided, and the traffic monitoring activity of a point on the route calculated by the route calculation function may be notified at an early stage when the distance is long.

The distribution information obtained by the notification terminal according to a preferred aspect of the present invention includes accuracy information indicating the accuracy of the distribution information,
The notification mode is changed according to the accuracy of the obtained distribution information.
If the notification mode is changed according to the accuracy of the distribution information, the user who has received the notification can determine the accuracy of the distribution information and cope with it. If the traffic monitoring activity corresponding to the distribution information was not actually performed, the user's confidence in the distribution information could be greatly impaired, but if the accuracy was low, it was also reported that Loss of trust in the company can be suppressed.

In the notification terminal according to a preferred aspect of the present invention, the relationship between the notification mode of the distribution information and the accuracy of the distribution information can be set by a user operation.
While there are users who do not want to receive notification of distribution information whose authenticity is not certain, there are also users who want to make their own judgment after receiving notification of all distribution information regardless of the authenticity. If the configuration is such that the distribution information to be notified according to the operation of the user can be selected as described above, the distribution information can be appropriately notified to various users.

A notification terminal according to a preferred aspect of the present invention is capable of acquiring vehicle information indicating a situation of a mounted vehicle, and changes a notification mode of distribution information according to the acquired vehicle information.
A notification terminal according to a preferred aspect of the present invention is capable of acquiring a speed as the vehicle information, and changes a notification mode of distribution information regarding speed control according to the acquired speed.
For example, when approaching the point of the traffic monitoring activity of speed control or when the speed of the vehicle is high, the notification that the driver suppresses the speed, such as outputting the notification of the corresponding distribution information by voice or generating an alarm sound, etc. Good to do. On the other hand, if the same notification is performed when the speed is low due to traffic congestion or the like, there is a possibility that the driver who cannot output the speed at all may be frustrated. In such a state, it is preferable to refrain from notifying the distribution information according to the approach.

The notification terminal according to a preferred aspect of the present invention is capable of notifying the distribution information and notifying the existing traffic information stored in advance regarding the traffic monitoring activity.
The notification of the regulated traffic information is suitable for notification of traffic monitoring activities such as fixed speed control. On the other hand, the notification of the distribution information is suitable for the notification of traffic monitoring activities that require real-time properties, such as mobile orvis, check-up, and patrol by police car. By combining the two, it is possible to provide detailed support for the safe driving of the driver as the user.

Although not shown in FIGS. 5 and 6, the power button 200 (FIG. 8) and the like are arranged on the outer peripheral side surface. In the driving support system 1 of the present example, as shown in FIG. 7, a state where the mobile terminal 2 is fixed to a dashboard or the like of the vehicle using the in-vehicle holder 19 or the like is a preferable usage form.

  As shown in FIG. 8, a control board on which an electric circuit forming the control unit 20 is formed is housed inside the portable terminal 2. The control unit 20 includes a camera substrate 22 on which a CMOS element and a lens are mounted, an amplifier substrate 23 for driving a speaker 230, a power button 200, a touch sensor sheet 211, a liquid crystal display unit 212, a wireless transceiver 241. , A GPS receiver 242, a clock unit 243, etc., are electrically connected.

  The wireless transceiver 241 is means for executing wireless communication in a predetermined frequency band. The wireless transceiver 241 of this example can transmit and receive digital voice data obtained by digitizing telephone voice by circuit switching, and transmit and receive digital data such as post information, post target information, application programs and map data by packet communication. It is possible.

  The GPS receiver 242 is a receiver that receives a GPS signal coming from a GPS satellite and outputs the current time, position information (latitude and longitude) of the current position, current speed, altitude, and the like. The GPS receiver 242 is incorporated in the main body of the mobile terminal 2 so as to be located above the center on the rear side when the vehicle is in a vertical position as shown in FIG.

  As shown in FIG. 8, the control unit 20 includes a CPU 201, a ROM 202, a flash ROM 203, a RAM 204 as storage elements, an I / O unit 205 serving as an input / output interface, and the like. The ROM 202 stores various control programs including the BIOS and the like. The flash ROM 203 stores various installed processing programs. The RAM 204 is a readable and writable storage element that is also used for a work area of the CPU 201 and temporary writing.

  The control unit 20 causes the CPU 201 to execute a program read from the ROM 202 or the flash ROM 203, so that a telephone display function, a data communication function, a map display function of displaying a map on the touch panel 21, and a post information generation function of generating post information , A posting function for posting posting information, a warning function for traffic monitoring activities, and the like. Each means for realizing these functions is formed in the control unit 20.

  The posting information generation function and the posting function are incorporated by installing dedicated posting software. This posting software can be downloaded from the application server 15 on the premise of membership registration on the driving support system 1 side (see FIG. 1). The posting software installed in the mobile terminal 2 incorporates encrypted data of a member ID and a login password to be given to a registered member. In order to start the posting software on the mobile terminal 2, the member ID and password given at the time of registration are required to be entered, and a complete match between the information embedded as encrypted data and the entered information is required. It has become. In the driving support system 1 of the present example, when starting the posting software, an entry of an unspecified person other than the member is avoided beforehand by requesting the input of the member ID or the like.

The storage area of the flash ROM 203 is provided with a map database storing map data and a GPS target information database 111 storing GPS target information related to traffic monitoring activities. The GPS target information includes existing traffic information such as N system installation information, posted target information distributed from a posting server, and the like.
The map data (MAP data) can be downloaded from a server that provides the map (see FIG. 1). In this example, one of the posting software application servers 15 also serves as a map server.
The existing traffic information is stored in the GPS target information database 111 when the posting software is installed.
The post target information is stored in the GPS target information when distribution is received, and thereafter, is deleted when a predetermined time has elapsed.

The storage area of the flash ROM 203 is further provided with a posting pin storage area for storing information on the traffic monitoring activity to be posted. The posted pin storage area can store posted pin information on traffic monitoring activities to be posted, up to a maximum of four posts. The posted pin information is composed of the following information.
-Time information indicating the pin registration time (posted position registration time) at which the posted pin was registered on the map-Position information (latitude and longitude, Address, the direction of the vehicle in which the direction of travel of the vehicle is reversed by 180 degrees)
・ Activity content information (including type information) indicating the type, implementation mode, method, etc. of traffic monitoring activities

The basic operation of the mobile terminal 2 of the present example will be described.
On the home screen (not shown) of the portable terminal 2 on which the posting software is installed, an icon of the posting software (not shown) is displayed. When capturing the touch operation on this icon, the control unit 20 of the mobile terminal 2 displays the startup splash screen 21A on the touch panel 21 and then displays the login screen 21B as shown in FIG. The login screen 21B is a screen for requesting input of a member ID and a login password registered in the driving support system 1 side.

  The control unit 20 checks whether the member ID and the login password input via the login screen 21B completely match the member ID and the login password recorded in the posting software. When the member ID and the login password can be collated, the control unit 20 switches the display on the touch panel 21 to the home screen 21C. The home screen 21C is a screen on which a map around the point of interest is displayed. In the lower part of the screen, in addition to the pin setting button 251 and the setting button 252, a WEB for guiding to a product site of a radar detector on the Internet is provided. The guidance button 255 is arranged.

On the screen of the home screen 21C, the display area of the map is set such that the point of interest coincides with a predetermined position at the lower center of the screen. The current position acquired by the GPS receiver is usually set as the point of interest. Unless a user operation for changing the point of interest is input, the control unit 20 sets the current position as the point of interest and displays a map around the current point on the home screen 21C. While the vehicle is running, the display area of the map is changed as needed so that the vehicle mark 250 representing the current position is located at a predetermined position on the lower center of the screen.
The “Spanner” mark setting button 252 at the lower right of the home screen 21C is an operation button for displaying the various setting screens 21D of FIG. On the various setting screens 21D, it is possible to change settings such as a warning display mode, a sound output mode, a setting of a ranking of a warning, a map display mode, and the like. The pin setting button 251 on the left of the setting button 252 is an operation button for registering a posting pin at a point of interest (usually the current position).
Home screen 21C is a basic screen displayed when post pin 262 has not been registered. On the other hand, when one or more posting pins are registered, the standby / post screen 21E (FIG. 11) of FIG. 11 to which a posting button 253 for starting posting is added becomes the basic screen.

  When displaying the home screen 21C or the standby / post screen 21E as shown in FIGS. 9 and 11, the control unit 20 refers to the GPS target information database 111 and acquires existing traffic information or posted target information around the current position. . The control unit 20 scrolls the information in the information display column 254 and displays the target icon 261 at a corresponding position on the map. In the information display column 254, character information that warns about a traffic monitoring activity near the current position is displayed. In the target icons 261 illustrated in FIG. 11, a circled H indicates a new H system, a circled N indicates an N system, and a circled P indicates parking. The display of these existing traffic information or post target information will be described later in detail.

  Next, the operation of the driving support system of the present example configured as described above will be described. Hereinafter, (1) the posting information posting operation by the portable terminal 2 (posting terminal 101A in FIG. 1), (2) the generation and distribution operation of the posting target information by the posting server 11 that has received the posting information, and (3) the posting target. The warning operation by the portable terminal 2 (the notification terminal 101B in FIG. 1) that has received the information distribution will be described in this order.

(1) Posting Operation of Post Information by Mobile Terminal 2 Posting operation in a situation where a map around the current position is displayed on the home screen 21C or the standby / post screen 21E while the vehicle is running will be described.
The user of the posting software can register the current position by touching the pin setting button 251 (FIG. 11) of the home screen 21C or the standby / posting screen 21E when witnessing a traffic monitoring activity such as mobile orvis. is there. The control unit 20 that has detected the touch operation of the pin setting button 251 acquires the time at that time, the latitude / longitude of the current position, and the traveling direction from the GPS receiver 242 and temporarily stores them.

  The control unit 20 confirms an empty area in the posted pin storage area, and stores new posted pin information in the empty area. At the time of registration of the posting pin 262, time information and position information forming a part of the posting pin information are stored based on the temporarily stored time, latitude and longitude, and traveling direction. The time information is the temporarily stored pin registration time. The position information is a temporarily stored latitude and longitude, a corresponding address, and a control direction obtained by inverting the temporarily stored traveling direction by 180 degrees. When there is no empty space in the posted pin storage area, the first posted pin 262 in time is deleted, and the corresponding posted pin information stored in the posted pin storage area is deleted, so that the empty area is deleted. Secured. On the map displayed by the standby / post screen 21E, the post pin 262 is set at a position corresponding to the position information of the post pin information. Note that up to four posting pins 262 can be set, and numbers are assigned in order from the earliest registration time. The posted pin information in the posted pin storage area is stored in a state where the pin numbers of the corresponding posted pins are associated with each other.

  When detecting a touch operation on post button 253, control unit 20 displays a pin list screen 21F (FIG. 12) displaying a list of posted pin information stored in the posted pin storage area on touch panel 21. On the pin list screen 21F, a return button 257 is arranged in addition to four pin selection buttons 256 for each posting pin. On the right side of the pin selection button 256, the corresponding posted pin information is displayed in text. This text display is the display of posted pin information excluding the activity content information of the traffic monitoring activity, and includes the display of the latitude and longitude, the address, and the control direction in addition to the pin registration time. In this example, since the control direction is set as the essential information of the posted information, in FIG. 12, the third pin button 256 whose direction is undetermined other than the unregistered fourth pin button 256 cannot be operated. It has become.

  Note that the azimuth measurement by the GPS function of the mobile terminal 2 in this example is performed by using a radio wave broadcast from a plurality of broadcasting stations such as a space segment of GNSS (artificial satellite such as GPS, SBAS, GLONAS, COMPASS) or a mobile terminal base station. The measurement is performed by the measurement based on the Doppler shift amount or by a method relative to the past positioning point. After the 1st Fix is completed (after the first positioning has been completed), it is determined when the vehicle speed reaches 10 km / h or more. After that, although the value of the measured azimuth fluctuates according to traveling, the azimuth measurement remains in a determined state until the power is turned off. After the azimuth measurement is determined, the pin setting button 251 of the standby / post screen 21E can be operated even if the current position is not located, but the post pin 262 is not set on the map because the current position cannot be acquired. The display is displayed during the search (not shown). Thereafter, the current position is acquired according to the return to the positioning state, and the posting pin 262 is set.

When the operable pin selection button 256 (the first and second pin selection buttons 256 in FIG. 12) in the pin list screen 21F is touch-operated, the control unit 20 transmits the posting screens 21G to 21K to the touch panel 21. 13 to 16) are displayed as appropriate, and activity content information to be stored as posted pin information is generated.
The posting screen 21G is a screen for selecting the type (category) of the traffic monitoring activity. The posting screens 21H and 21H are screens for selecting an embodiment and a method of the traffic monitoring activity. Post screen 21J is a confirmation screen for the generated posted information. Post screen 21K is a display screen indicating that the posting has been completed.
Here, the type of the traffic monitoring activity is the type of the traffic monitoring activity of Orbis, N system, check, and enforcement. The implementation of traffic monitoring activities and variations of methods differ depending on the types of traffic monitoring activities. For example, in the case of the N system, there is no variation in the embodiment and the method. On the other hand, there are variations of the mouse trap and the mobile orvis for the control, and there are also variations of the mobile orvis such as the radar type and the stealth type. Whether or not the posting screens 21H and 21H are displayed during the posting operation differs depending on the type of traffic control activity and the like.

  Of the posting screens 21G to 21K, the posting screens 21G, 21J, and 21K are screens that must pass through regardless of the type of the target traffic monitoring activity. On the other hand, the posting screens 21H and 21H are screens that do not pass depending on the type of the traffic monitoring activity. For example, as shown in FIG. 14, when the type of the traffic monitoring activity is the N system (vehicle number reading system), the posting screens 21H and 21H are not displayed because there is no variation in the embodiment or the method. On the other hand, as shown in FIG. 15, when the type of traffic monitoring activity is control, the embodiment and method are subdivided, so that it is necessary to display the posting screens 21H and 21I and allow the user to input information.

  The control unit 20 generates the activity content information corresponding to the operation button selected by the user operation in the process of passing through the posting screens 21G to 21G, and stores it in the posting pin storage area as needed. The activity content information that forms a part of the posting pin information is determined when the posting screen 21J is reached. On the posting screen 21J, a posting button 259 and a return button 257 are arranged together with the text display of the generated posting information. When a touch operation on the post button 259 is detected, the control unit 20 reads out the corresponding post pin information from the post pin storage area, and adds the post member information such as a member ID and a registrant ID to post information. Generate The control unit 20 transmits the post information thus generated to the post server 11 and switches the display of the touch panel 21 to the post screen 21K when the transmission is completed. This posting screen 21K is displayed for a few seconds, and then the display is ended in response to the return to the home screen 21C or the standby / posting screen 21E.

  Note that the posting screens 21H and I except for the posting screen 21G for selecting the embodiment and method of the traffic monitoring activity are provided with a selection button 258 "Other / Unknown". When the “other / unknown” selection button 258 is operated, the control unit 20 determines the activity content stored in the posting pin storage area without passing through the sequence of the posting screen 21 illustrated in FIGS. The information is determined, and the posting screen 21J is immediately switched and displayed. In the mobile terminal 2 of this example having such specifications, for example, even if the user does not know the difference in the method of orbis (speed violation), the detailed level of “Orbis is installed” according to the knowledge level Can be generated relatively easily. On the other hand, if the user has a high level of knowledge about the difference between the Orvis methods, the user can select any of the methods on the posting screen 21I to generate post information with a high level of detail.

  Also, as shown in FIG. 15, when the type is control, the posting screen 21I can be passed by selecting the “other / unknown” selection button 258 on the posting screen 21H. For a user with a very low level of knowledge, it may be awkward for the posting screen 21 to be fed out one after another, while the specification in which a part of the posting screen 21 is passed as described above is a user who is not very familiar. It is also effective in activating the posting activity.

The posting information posted by the operation of the mobile terminal 2 as described above includes the following information as in the text display on the posting screen 21J. The time information and the position information are information stored in the posting pin storage area when the posting pin 262 is registered, and the activity content information is stored in the posting pin storage area while passing through the posting screens 21G to 21G. This is the stored information. The member information is added when posting to the posted pin information read from the posted pin storage area.
・ Time information indicating the pin registration time ・ Position information (latitude / longitude, address, direction) of the monitoring position where traffic monitoring activities are performed
-Activity content information indicating the type, implementation mode, method, etc. of traffic monitoring activities-Member information of contributors such as member ID and registrant ID

(2) Generation and Distribution Operation of Post Target Information by Post Server 11 When the post server 11 receives post information from the mobile terminal 2, first, the post server 11 requests authentication of the member management server 12. The member management server 12 that has been requested to authenticate refers to the user management database 121 (FIG. 2) using the member information received from the posting server 11 and determines whether there is a corresponding member. When the corresponding member exists effectively, the poster ID of the member is returned from the member management server 12.

  When the posting server 11 has been authenticated by the member management server 12, the posting server 11 refers to the user status database 113 to check whether or not the poster has a posting prohibition flag. The posting server 11 deletes the posting information for which the posting prohibition flag is set without accepting it, and executes the receiving process for the posting information for which the posting prohibition flag is not set. In this reception process, first, the posted information is temporarily stored in association with the posted time (incoming time) of the posted information, and sorting is performed for each traffic monitoring activity. In this sorting, the condition of the commonality of the type that the traffic monitoring activity type is common, the condition of the local proximity that is located within a range (predetermined range) of a radius of 100 m, the predetermined time, Other post information that satisfies the condition of temporal proximity that post information has been posted in the post area is retrieved from the post area. When the other posted information that satisfies all the conditions can be searched, the newly received posted information is classified as having the same traffic monitoring activity as the other posted information, and is sequentially received as shown in the posted information list in FIG. The post numbers are assigned in order and stored in the posting area. On the other hand, when the past posting information that satisfies the condition of the type commonality, the location proximity, and the time proximity condition is not stored in the posting area, the posting server 11 A post information list similar to that of FIG. 17 is newly generated with newly received post information as a starting point (post number 001).

  When adding new posting information to the posting information list of FIG. 17, the posting server 11 refers to the user status database 113 using the poster ID of the new posting information, and refers to the posting evaluation of the poster. As described above with reference to FIG. 3, the items of the post evaluation for each contributor include items of the total number of posts, the number of correct posts, the number of incorrect posts, the correct post rate, and the overall evaluation. When adding new posted information to the posted information list in FIG. 3, the posting server 11 accumulates points of the overall evaluation (FIG. 3) of the poster to calculate and store the accumulated points. As will be described in detail later, the accumulated points are used as an evaluation value or the like of the accuracy of the post target information based on the post information. In this example, all pieces of posted information are recorded as shown in FIG. 17, but instead, posted information whose overall evaluation points are lower than the reference point is not registered in the list of FIG. You may delete it.

  The information detail level in the posted information list in FIG. 17 is a value indicating the degree of detail of the activity content information included in the posted information. In each of the posting screens 21H and I (FIGS. 13 to 16), the level of detail of the posting information generated by making a significant selection other than the other is 3, and only one of the posting screens 21H and I is displayed. Post information generated by making a significant selection is at detail level 2, and post information generated by making a significant selection only on the posting screen 21G is at detail level 1. As a matter of course, for the N system in which the posting screens 21H and I are not presented without any distinction between the embodiment and the method, the information detail level of all the posted information is level 1. On the other hand, there are various types, embodiments, and methods, and the information detail level of a mouse trap or the like in which the posting screens 21H and 21 are presented varies depending on the posting information from detail levels 1 to 3.

Here, a condition of temporal proximity and a condition of spatial proximity, which are conditions for sorting newly received post information, will be described.
The condition of temporal proximity is a condition that the pin registration time of the new posted information is included within a predetermined time based on the pin registration time of the preceding posted information. As the predetermined time, a different time is set for each piece of posted information as shown in FIG. 18 according to the overall evaluation of the poster of the preceding posted information (FIG. 3) and the traffic amount at the monitoring position. As the post information having a higher overall evaluation point in the post evaluation, a longer time is set as the predetermined time. In addition, depending on whether the monitoring position is an urban area or a county, whether or not the road is an arterial road, and the number of vehicles owned by the police station under the jurisdiction to which the monitoring position belongs, the larger the traffic volume assumed in advance, the shorter the predetermined time as the predetermined time. The time is set as the traffic amount is smaller.

  As shown in FIG. 18, for example, after the first post information is received, when the second post information that satisfies the above two conditions of the spatial proximity and the type commonality is received, the arrival time is: Within the predetermined time set for the first posted information (the time indicated by the downward arrow in the figure), the second posted information is classified as having the same traffic monitoring activity. Also, for example, for the fifth posted information that satisfies the above two conditions after the reception of the fourth posted information, the arrival time of the fifth posted information is after a predetermined time set in the fourth posted information has elapsed. , Within the predetermined time set in the third posted information. As a result, the fifth posted information is sorted if the third posted information and the traffic monitoring activity are common, similarly to the fourth posted information.

  The locational proximity condition is a condition that the position based on the new posted information is included within a radius of 100 m around the reference point. As shown in FIG. 19, the position of the reference point fluctuates as needed when the post information is sequentially sorted. Here, B1, B2, B3,... Represent each piece of post information before distributing the corresponding post target information, and A1, A2, A3,. Represents post information. The number following A or B indicates the order of posting. For example, the posting information of B1 is posting information that is the starting point of the first posting. A1 is post information posted first after distribution of the corresponding post target information. The vertical direction in the figure represents the transition of time. The left-right direction represents the position of the forward / backward direction on the road where the traffic monitoring activity to be posted is performed. With respect to the traveling direction of the vehicle, the right side indicates the backward side, and the left side indicates the forward side.

  Upon receiving the posting information B1 as the starting point, the posting server 11 first sets the corresponding monitoring position as the first reference point 1 (the circled point 1 in FIG. 19). Thereafter, when a monitoring position is set within a range of a radius of 100 m around the reference point 1 and new posted information B2 relating to a traffic monitoring activity of a common type is received, the monitoring position of the posted information B2 and the reference point A position that is located in the middle between 1 and 1 is set as a new reference point 2. When the monitoring position is set within a range of a radius of 100 m centered on the reference point 2 (point 2 in the circle) and new post information B3 relating to traffic monitoring activities of a common type is received, the post information B3 is monitored. A new reference point 3 (a point with a circle 3) is set to a distance obtained by dividing the distance between the position (B3) and the reference point 2 into three equal parts and a position separated from the reference point 2 toward the monitoring position (B3). Since the reference point 2 is a point based on two pieces of posted information, while the monitoring position (B3) is a point based on only one piece of posted information, the position of the reference point 3 is based on the concept of a weighted average. Determined at an intermediate position. After the reference point 3 is set in response to the reception of the post information B3, if the post information B4 is grouped, the distance between the monitoring position (B4) of the post information B4 and the reference point 2 is set to 4 A position separated from the reference point 3 toward the monitoring position (B4) by the equally divided distance is set as a new reference point 3.

  The weighted average coefficient differs between before and after the distribution of the post target information. Specifically, for the monitoring position of the post information before distribution, the weighted average coefficient is set to 1, for example, if the reference point is based on four pieces of post information, a new monitoring position and a new reference point Is shifted toward the new monitoring position by a distance obtained by dividing the distance by five. On the other hand, regarding the monitoring position of the post information after distribution, the coefficient of the above-mentioned weighted average is set to 2, and for example, if the reference point is based on six pieces of post information, the distance between the new monitoring position and the reference point is changed. It is shifted to the new monitoring position by twice the distance of 8 equal parts.

  The reason why the handling is different before and after the distribution of the post target information will be described. Before distribution, the traffic monitoring activity suddenly appears to all contributors, and it is necessary to determine the type and the like in a short time before passing. Therefore, there is a tendency that a registration operation or the like of a point of the traffic monitoring activity is performed after the point has passed, and the point of the post target to be actually registered is shifted forward (passing direction) from the actual point in the traveling direction. Probability is high. On the other hand, after the distribution, since it is known in advance that the traffic monitoring activity of the type related to the posted target information is performed, the type of the actually performed traffic monitoring activity is the same as the posted target information. There is a tendency for the accuracy of the determination of whether or not there is to be higher. In addition, it is very interesting whether traffic monitoring activities are actually taking place at the location related to the posted target information, and they will approach that location, so the registered location will be exactly the same as the actual location. easy. As mentioned above, if the coefficient of the weighted average when determining the reference point before and after distribution is different and the coefficient of the monitoring position of the post information after distribution is increased, post-delivery post where high accuracy of the monitoring position is expected The information can be immediately reflected on the position of the reference point, and the position accuracy can be improved.

The posting server 11 integrates the posting information and starts generating distribution target information for distribution for traffic monitoring activities in which the accumulated points in the posting information list in FIG. 17 have exceeded a predetermined reference point. The post target information includes the following information.
・ Time information indicating the earliest pin registration time in the posted information ・ Position information (latitude / longitude, address, direction) of the monitoring position where the traffic monitoring activity is performed
-Activity content information indicating the type, implementation mode, and method of traffic monitoring activity-Accuracy information indicating the degree of certainty of post target information

In the position information of the post target information, the latitude and longitude of the average position of the latest 10 pieces of post information, the address corresponding to the latitude and longitude, and the average direction of the latest 10 pieces of post information are set. . Note that the reference point (FIG. 19) for determining the locational proximity may be set to the latitude and longitude and the address in the position information included in the posted information.
In generating the activity content information of the post target information, the post server 11 refers to the post evaluation for each contributor (FIG. 3), and the total evaluation score is 7 or more, and the correct post rate is Select posting information by 70% or more contributors. In the case where the difference of the activity information of the selected post information is only the difference of the detail level and there is no difference in the embodiment and the method, the activity content information of the post information having the highest detail level is directly posted. It is set in the activity content information included in the target information. On the other hand, when there is a difference in the embodiment or the method, the activity content information determined by the majority decision is included in the posting target information. If it is not decided by majority vote, priority is given to the activity content information by the poster with the detailed and high regular post rate among the selected post information.
The latest accumulated points are set as they are in the accuracy information of the post target information.

  The posting server 11 of this example stores all the posting target information generated as described above in the new arrival information area, and distributes the posting target information other than the installation type orvis and the N system using the public communication line. I do. The posting server 11 stores the posting target information relating to the installation type orvis and the N system without distributing them, and then outputs the post target information in response to an output operation by a system administrator or the like. Post target information, which is also new information of the installation type Orbis and N systems, is visually checked by staff on the system side, and is registered in the existing GPS area (the GPS target information database 111 in FIG. 2) when it can be visually checked. The registered traffic information registered in this manner is distributed to a user such as a radar detector that warns of approach to GPS content such as an Orbis or N system, and is then downloaded to the mobile terminal 2. It is included in the posting software.

(3) Alarm Operation by Mobile Terminal 2 Next, an alarm by the mobile terminal 2 will be described. The mobile terminal 2 of this example can execute an alarm using the existing traffic information incorporated in the GPS target information database 111 when the posting software is installed, and the posted target information stored in the GPS target information database 111 upon receiving the distribution. It is. Such an alarm is executed while the home screen 21C (FIG. 9) or the standby / post screen 21E (FIG. 11) is displayed. On the home screen 21C or the standby / post screen 21E after receiving the post target information, the target icon 261C of the existing traffic information is displayed as a circular mark, and the target icon 261R of the post target information (distribution information) is square as shown in FIG. Displayed with the mark.

  The square target icon 261R of the post target information is displayed in different colors depending on the certainty represented by the certainty information included in the post target information. Those with a low degree of accuracy are displayed in a cool color, colors with a high degree of accuracy change to warm colors, and those with a high degree of accuracy are displayed in red. Alternatively, or in addition, the size of the square mark may be changed according to the accuracy of the post target information.

  When detecting the touch operation on the square target icon 261R, the control unit 20 of the mobile terminal 2 displays a data display screen 21L for displaying detailed data of the post target information and the like as shown in FIG. On the data display screen 21L, in addition to the detailed data of the post target information, the accuracy, the number of posts, the occupation ratio of the highly evaluated contributors, the past results of similar traffic monitoring activities, and the contributor list are displayed. When detecting a touch operation on any of the contributors in the contributor list, the control unit 20 switches and displays the content of the post by the contributor and a display screen (not shown) of the overall evaluation points of the contributor. . Note that, also at the time of a touch operation on the circular target icon 261C corresponding to the existing traffic information, detailed information of the corresponding existing traffic information is displayed.

  Further, as shown in FIGS. 22 and 23, the mobile terminal 2 displaying the home screen 21C or the standby / post screen 21E monitors the traffic monitoring position of the traffic monitoring activity of the existing traffic information or the post target information (see FIG. 22 and FIG. 23). When approaching (GPS target), an alarm corresponding to the type is executed. While displaying the home screen 21C or the standby / post screen 21E, the control unit 20 refers to the GPS target information database 111 and acquires existing traffic information or post target information around the current position. The control unit 20 calculates the distance from the current location of the GPS target of the existing traffic information or the posted target information in the vicinity as needed, and detects the approach to the corresponding GPS target according to the distance.

FIG. 22 is an example of a warning when approaching the installation position (monitoring position) of the N system and a warning when approaching the seat belt control area (monitoring area). The former is an example of a traffic monitoring activity alert performed at points rather than areas. The latter is an example of a traffic monitoring activity alert performed in an area.
If the control unit 20 reaches a point of 340 m trouble to the installation position of the N system during the display of the standby / post screen 21 </ b> E, the control unit 20 displays a text display such as “N system 340 m” in the information display column 254 and the N system. Is displayed in a pop-up display on the screen.
When the control unit 20 reaches a point 340 m short of the seat belt control area, the control unit 20 displays a text display such as “Seat belt control 340 m” in the information display field 254 and displays a corresponding illustration 265 in a pop-up display on the screen. . Further, when the vehicle is traveling in the seat belt control area, that is, when the current position belongs to the area, the control unit 20 displays a text display such as “Seat belt control” in the information display column 254. When the vehicle passes through the area, that is, when the current position goes out of the area, the character display in the information display column 254 is erased, and the original standby / post screen 21E and the like are restored.

  FIG. 23 is an example of a warning when approaching the installation position of the expressway orbis. The timing of starting the alarm when approaching the orbis installation position on the highway differs depending on whether or not the vehicle speed at that time exceeds the speed limit. When the speed limit is exceeded, the control unit 20 displays a text display such as “Expressway Orbis 2000m” when reaching a point 2,000m away, as shown in the leftmost diagram in FIG. And the corresponding illustration 265 is displayed in a pop-up display. In addition, the control unit 20 executes an audio warning such as "2 km ahead, XX road, loop coil orvis."

On the other hand, when the speed is within the speed limit, the control unit 20 displays a text display such as “Expressway Orbis 1000m” in the information display column 254 when the vehicle reaches the point of 1000m as shown in the center diagram in FIG. At the same time, the corresponding illustration 265 is displayed in a pop-up. In addition, an audio warning such as "1 km ahead, XX road, radar type orbis." Thereafter, when the vehicle arrives at a point 500 m before, a sound such as “The camera is on the right side” is output from the speaker 230.
Furthermore, when the vehicle arrives at a point 300 m immediately before, an information display field 254 for displaying a text to that effect is displayed, and an audio warning such as “300 m ahead, ○ road radar type Orbis. The running speed is 120 km.” Execute.

  It is also possible to add the disclosure control information to the posting target information distributed by the posting server 11. In this case, it is possible to notify and warn public disclosure information as shown in FIG. FIG. 11 shows an example in which the text display “Seat belt enforcement week starts on August 1” is scroll-displayed in the information display field 254.

  As described above, by using the mobile terminal 2 of the present example, it is possible to generate post information including the type information indicating the type of the traffic monitoring activity performed to promote traffic safety and the position information indicating the monitoring position. , Can be posted to the posting server 11. The posting server 11 generates posting target information (distribution information) including type information and position information on the traffic monitoring activity by integrating a plurality of pieces of posting information sharing the same traffic monitoring activity. The other mobile terminal 2 can execute a notification, a warning, and the like using the posting target information from the posting server 11.

The posted information from the mobile terminal 2 includes information having a high real-time property, while the accuracy of the posted information varies, and there may be correct information and incorrect information. If a plurality of pieces of posted information that are not determined to be true are delivered as they are, there is a possibility that confusion may arise as to which information the portable terminal 2 that has received the information may believe.
On the other hand, according to the posting server 11 of the present example, it is possible to distribute the posting target information whose accuracy is improved by integrating a plurality of pieces of posting information. The post target information is easy-to-use and useful information that balances real-time properties based on the post information and accuracy improved by information integration.

  In particular, in this example, the post information to be integrated is sorted by judging three conditions of temporal proximity, commonality of types of traffic monitoring activities, and location proximity. According to such sorting, it is possible to accurately extract post information for a specific traffic monitoring activity. In addition, in generating post target information by integrating post information thus classified, the post information having high accuracy is selectively used after evaluating the post information accuracy. Since the post target information is information generated by integrating post information with high accuracy, the accuracy is high. In addition, post target information generated by integrating post information that has undergone the evaluation of accuracy is easily evaluated for accuracy, and is easily managed by the distributor and the recipient. The distribution side may selectively distribute the post target information according to the accuracy. On the side receiving the distribution of the post target information, it is also possible to selectively execute the notification or the warning according to the accuracy.

  As described above, the driving system 1 of this example is a system for distributing posted target information based on posted information related to traffic monitoring activities such as traffic control and inspection, and assisting driving. This is an excellent system that achieves both real-time performance and accuracy (reliability).

  You may be comprised so that cancellation information to the effect that the traffic monitoring activity concerning the distributed posted target information is not implemented can be generated as posted information. For example, a cancel post button for transmitting cancellation information may be additionally arranged on the data display screen 21L of FIG. 21 displayed by touching the square target icon 261R (FIG. 20) of the standby / post screen 21E. good. It is preferable that the post server 11 authenticates the received cancellation information in the same manner as in the case of the post information. When distributing the post target information after receiving the cancellation information, it is also possible to include information such as the fact that the cancellation information has been received and the number of cancellation posts. A cancellation post display field for displaying such information may be added to the data display screen 21L of FIG. Furthermore, the accuracy of the cancellation information is evaluated based on the number of posts of the same type of cancellation information and the occupation ratio of highly rated contributors, and when the accuracy exceeds a predetermined threshold, distribution of the corresponding post target information is stopped. Good to do.

After the distribution of the post target information is completed, the original post information may be stored in the new arrival information storage area. These pieces of posted information are useful as reference information when considering whether to newly register the posted target information as existing traffic information.
After the distribution of the post target information is completed, it is preferable that the post information is evaluated for each post information in the post information list in FIG. 17 and the evaluation result is reflected in the content of the evaluation item. If the poster makes a correct post, the post rating will increase steadily, whereas if the post makes an incorrect post, the post rating will drop steadily, resulting in a difference in the post rating. If the difference between the post evaluations becomes remarkable, when the post server 11 receives the post information, it becomes possible to easily determine the handling of the post information, the integration of the integrated information becomes easy, and the accuracy of the post target information can be improved. .
Instead of this example, while the system accepts a post from a poster that cannot be specified, the post information of an unspecified specific person may be handled as post information with low accuracy. In this case, the number of posts can be increased.

  In this example, the display is performed in such a manner as to be colored according to the accuracy of the post target information. In addition to this, a threshold value regarding the accuracy of whether to display the post target information may be adjustable by a user operation. In addition, the display mode of the post target information with respect to the accuracy may be configured to be set by a user operation.

  In addition, after registering the posting pin 262 in the mobile terminal 2 and before transmitting the posting information, the position of the posting pin 262 on the map may be corrected by a user operation such as dragging. In this case, the post information may include pin correction information indicating that the position correction operation of the posting pin 262 has been performed. The posting server 11 estimates that post information including the pin correction information has higher positional accuracy of the position information than post information not including the pin correction information, handles the post information, and reflects the post information on the post target information. good.

The mobile terminal 2 may be configured so that the position of the target icon 261R (FIG. 20) of the post target information can be corrected by a user operation. Further, the post information may include icon correction information indicating that the position correcting operation of the target icon 261R has been performed. It is preferable that the posting server 11 handles the post information including the icon correction information assuming that the position accuracy is high, and reflects the post information on the position information of the post target information.
Post server 11 may be provided with a map database. If well-known map matching is performed using the map data so that the monitoring position related to the posted information is located at the specific point, the positional accuracy of the monitored position can be secured, and the positional accuracy of the posted target information can be improved. The specific point in the map matching may be, for example, a point on a road or a point where enforcement has been performed in the past.

  In response to a touch operation on the target icon 261R (FIG. 20) relating to the post target information, the mobile terminal 2 of the present example displays a data display screen 21L for displaying detailed data of the post target information as shown in FIG. In the data display screen 21L, the contributors are listed in the order of the time of the post information, but instead, the contributors with the higher total evaluation points may be displayed in a ranking.

  In this example, as shown in FIG. 4, the points of the comprehensive evaluation of the contributors are determined based on the number of correct contributors and the correct contribution rate, thereby evaluating the accuracy of post information by each contributor. As an alternative method of evaluating the accuracy of the posted information, a method based on an evaluation from another user, a method based on the degree of approach of a distance from previously collected past control position data, and the like may be considered. For example, when a touch operation (for example, double tap) is performed on the target icon 261R (FIG. 20) of the post target information, the integrated monitoring position of the original post information may be displayed. Furthermore, if the evaluation screen of the corresponding poster is switched and displayed by touching each monitoring position, each poster can be evaluated relatively easily from the portable terminal 2 side.

The data specification of the posted information handled by the driving support system of this example is as shown in FIG. In the figure, header information and the like required for communication are not shown. In the posted information of this example, the member information of Example 1 is replaced with the product information (such as a serial number) of the radar detector 4. In addition, the posted pin information of the present example includes freshness information indicating the execution time of the traffic monitoring activity to be posted and azimuth type information indicating the type of the control azimuth (FIGS. 34) has been added. The details of each data such as X, Y, A,... Constituting the posted pin information in FIG. 32 are as shown in FIG. The contents of each of the data T, R, and M among the data in FIG. 9A are as shown in FIGS. 9B, 9C, and 9D.

The freshness information is information indicating the time of the traffic monitoring activity to be posted. As shown in FIG. 33 (c), a data value representing freshness is defined according to the execution time of the target traffic monitoring activity. For example, if the posted information is for a traffic monitoring activity that is currently being carried out, the freshness value is zero, and the posted information is for a traffic monitoring activity that has been performed within one month over one week. In this case, the value of the freshness becomes 20. On the other hand, for posted information for permanent installation type orvis, the freshness data value is 255.
The direction type information is information that supplements the control direction included in the position information. By using the azimuth type information, it is possible to specify the control direction of the monitoring activity in the opposite lane and to specify whether the traffic monitoring activity is on the right or left side of the traveling lane. For example, in the case of a traffic monitoring activity for the traveling lane, 0x01 which is 180 degrees inverted from the traveling direction of 0x02 (the traveling direction of the vehicle) in FIG. 34 is the type of the control direction. For example, when a posting pin is registered in front of the orbis installed in the median strip, the orbis are set diagonally to the right of the traveling lane. In this case, the type of the control direction is the direction of 0x10 in FIG.

  In the driving support system 1 of this example, (1) generation of post target information using the radar detector 4, (2) transmission of post information by the mobile terminal 2, (3) authentication of post information by the member management server 12, Are different from the driving support system of the first embodiment. Hereinafter, the contents of each of the operations (1) to (3) will be described.

(1) Generation of Post Information When the control unit 40 of the radar detector 4 detects the operation of the memory button 522 during the display of the map screen 62 of FIG. 29, the control unit 40 including the pin setting button 634 as shown in FIG. Is displayed in a pop-up on the screen. As the registration menu button 63, in addition to the pin setting button 634 for registering the post pin 64 (FIG. 36), an ITY map button 631 for displaying the latitude and longitude of the vehicle positioning position when the button is pressed in a two-dimensional barcode, There is a My Area button 632 for registering a My Area, and a Cancel button 633 for canceling a registered area.

  When the pin setting button 634 is touched, the control unit 40 sets the posting pin 64 at the current position on the map screen 62 as shown in FIG. 36, and sets the position information (latitude and longitude, address, control direction) of the posting target. ) And the pin registration time are registered in the posting pin storage area. In the radar detector 4 of the present example in which up to four pieces of posted pin information can be registered in the posted pin storage area, up to four posted pins 64 can be registered from the first pin to the fourth pin. In the figure, since all the pins are empty, the first pin is set as the post pin 64 at the current position, and the position information and the pin registration date and time at that time are stored in association with the first pin. It is an example. It should be noted that the activity content information indicating the type, embodiment, method, and the like of the traffic monitoring activity is generated according to a subsequent user operation (FIGS. 40 to 42) and stored in the posting pin storage area.

If all four posting pins 64 are registered and four pieces of posting pin information are stored in the posting pin storage area, the registration menu button 63 of FIG. You. Here, the registration menu button 634A including the display of "Pin is full." Indicates that the posting pin 64 (FIG. 36) cannot be registered.
In this example, since the control direction is essential information in the posted information, the post pin 64 cannot be registered in a state where the traveling direction by the GPS function is undetermined, as in the first embodiment. I have. When the memory button 522 is operated in a state where the traveling azimuth is undetermined, the control unit 40 pops up a registration menu button 63 including a registration menu button 634B indicating azimuth undetermined (FIG. 38). When the memory button 522 is operated in a non-positioning state in which positioning by the GPS function is not performed, the control unit 40 displays a telop message indicating that a GPS search is being performed on the upper part of the map screen 62 (FIG. 39). ).

  When detecting a touch operation on the map screen 62 (FIG. 29 and the like), the control unit 40 displays the setting screen 67A at the top of FIG. 40. Various menu buttons including a posting button 670 for posting posting information are arranged on the setting screen 67A. When the post button 670 is touched, the control unit 40 switches to the display of the post pin menu screen 67B in the middle of FIG. The post pin menu screen 67B is a screen in which a confirmation button 671A and a delete button 671B are arranged for each post pin. Regarding unregistered posting pins, the operation buttons 671A and 671B are displayed in a shadow and are inoperable. The control unit 40 that has detected the touch operation on the pin confirmation button 671A reads the posted pin information corresponding to the posted pin from the posted pin storage area. The control unit 40 displays text information of position information (latitude / longitude, address, control direction) and time information (pin registration date / time) of the read posted pin information, and a post button 672 for starting a posting process. The placed pin confirmation screen 67C is displayed. Generation of post information is started in response to a touch operation on post button 672.

  When detecting the touch operation of the posting button 672 in the pin confirmation screen 67C as shown in FIG. 41, the control unit 40 appropriately changes the posting screens 67D to 67I in FIGS. 41 and 42 according to the type of the traffic monitoring activity and the like. Is displayed on the touch panel 45. The posting screens 67D to 67F in FIG. 41 are screens for generating activity content information (FIG. 32) such as the type (category) of the traffic monitoring activity to be posted, its implementation mode, and the method. The posting screens 67D to 67F correspond to the posting screens 21G to 21I (FIGS. 13 to 16) of the first embodiment, respectively. The control unit 40 adds the activity content information generated in response to a user operation on the posting screens 67D to 67F to the posting pin information stored in the posting pin storage area. Except for the posting screen 67D for selecting the type of the traffic monitoring activity to be posted, the posting screens 67E and F for selecting an embodiment, a method, and the like have operation buttons for selecting other or unknown. The purpose of providing operation buttons for selecting other or the like on the posting screens 67E and F is to simplify posting by a user who is not very familiar with traffic control and activate the posting.

The posting screen 67G in FIG. 42 is an operation screen for inputting freshness information (FIG. 32) indicating the execution time of the traffic monitoring activity to be posted. On the posting screen 67G, in addition to the operation buttons for selecting “currently in operation”, operation buttons for one week or less, operation buttons for one month or less, operation buttons for three months or less are arranged. The driving support system 1 according to the first embodiment is a system that is assumed to post a traffic monitoring activity that is currently being performed, while the system according to the present embodiment also enables posting that targets a past traffic monitoring activity. Has become. The control unit 40 adds the freshness information corresponding to the operation button selected on the posting screen 67G to the posting pin information stored in the posting pin storage area.
The posting screen 67H is a posting screen for selecting the type of the control direction. The posting screen 67H includes “traveling lane”, “opposite lane”, “right direction”, “left direction”, “traveling lane right side”, “traveling lane left side”, “opposite lane left side”, “opposite lane” There is an operation button on the right side of the lane. Control unit 40 adds the orientation type information (FIGS. 32 to 34) corresponding to the operation button selected on posting screen 67H to the posting pin information stored in the posting pin storage area.

When any of the operation buttons is operated on the posting screen 67H as described above, generation of the posting pin information (FIG. 32) is completed. The control unit 40 reads the posted pin information from the posted pin storage area and adds the product information (FIG. 32) to generate the posted information. Then, a code image 670 in which the posting information is recorded is generated, and a posting screen 67I including the code image 670 is displayed on the touch panel 45 as shown in FIG.
The posting user may take the code image 670 with the mobile terminal 2 that has started the posting software corresponding to the code image. In the mobile terminal 2 that has photographed the code image 670, image processing is performed, and the code image 670 in the photographed image is cut out and the posted information recorded in the code image 670 is read. The control unit of the mobile terminal 2 transmits the post information thus read to the post server 11 immediately.

  When receiving the posted information, the posting server 11 first requests authentication of the member management server 12. The member management server 12 that has been requested to authenticate refers to the user management database 121 using the product information (such as a serial number) received from the posting server 11 and determines whether there is a corresponding purchaser. When the corresponding purchaser exists effectively, the poster ID of the purchaser is returned from the member management server 12. When the posting server 11 has been authenticated by the member management server 12, the posting server 11 refers to the user status database 113 to check whether or not the poster has a posting prohibition flag. The posting server 11 deletes the posting information for which the posting prohibition flag is set without accepting it, and executes the receiving process for the posting information for which the posting prohibition flag is not set.

The reception process of this example is different from the posted information in which the data value of the freshness information (FIG. 33) is zero and the other posted information. The freshness information is zero, that is, real-time posted information for the traffic monitoring activity currently being performed is handled in the same manner as in the first embodiment, and becomes the original information of the posted target information for distribution.
On the other hand, regarding the other posted information, that is, the posted information relating to the permanent traffic monitoring activity such as the N system (the data value of the freshness information is 255) and the posted information relating to the past traffic monitoring activity, It is stored in the same new arrival information area and becomes the original information of the newly registered existing traffic information.
The other configuration and operation and effect are the same as in the first embodiment.

  Note that the posting screens 67E to 67H (FIGS. 41 and 42) may be provided with a “immediate posting button” for jumping to the posting screen 67I. If any of the orbis button, the N system button, the control button, and the check button is selected on the posting screen 67D corresponding to the posting screen 21G (FIGS. 13 to 16) of the first embodiment, the type of the traffic monitoring activity is determined. . If the type of the traffic monitoring activity is determined in this way, post information including the type information indicating the determined type can be generated even if the post button is immediately operated on the post screens 67E to 67H. .

  Deletion of the registered post pin 64 (FIG. 36 and the like) can be executed by operating the delete button 671B on the post pin menu screen 67B in the middle part of FIG. When this delete button 671B is operated, as shown in FIG. 43 (a), the deletion of the corresponding posted pin is completed via a screen for confirming the deletion and a screen for displaying that the deletion has been completed. By operating the system button arranged at the lower right corner on the setting screen 67A at the top of FIG. 40, the data deletion screen can be switched and displayed as shown in FIG. 43 (b). If the post pin button is selected on this data deletion screen, the post pin and the corresponding post pin information can be collectively deleted.

The post target information distributed by the driving support system 1 of the present example is information on a traffic monitoring activity that is currently being carried out, as in the first embodiment. Alternatively or additionally, post target information generated by integrating post information relating to past traffic monitoring activities whose freshness information (FIG. 33) is not 255 or zero may be distributed. In this case, for example, one or more pieces of posted information on traffic monitoring activities conducted two months ago, posted information on the same type of traffic monitoring activities one month ago, and the same type of posted information within one week It is possible to integrate post information on a traffic monitoring activity with post target information on a point of interest where a traffic monitoring activity is frequently performed.
Here, in order to sort the above one or more pieces of posted information as the posted information on the common traffic monitoring activity two months ago, the temporal proximity and the locational proximity of the implementation time are required. And the three conditions of type commonality must be satisfied. In order for posted information for a specific traffic monitoring activity two months ago to be sorted as common traffic monitoring activity one month ago, the location It is necessary to satisfy two conditions of general proximity and type commonality.

  In this example, the posted information is transferred to the mobile terminal 2 using the code image 670 (FIG. 42) displayed by the radar detector 4. Instead, the radar information detector 4 and the mobile terminal 2 may be connected in a communicable state by wireless communication such as WiFi, and the posted information may be transferred (see FIG. 1). For example, when the post button displayed on the touch panel 45 of the radar detector 4 is operated while the dedicated software is running on the mobile terminal 2, the posted information is posted via the mobile terminal 2. It is also possible to configure as follows. In order to provide the radar detector 4 with a WiFi function, a WiFi module or the like may be incorporated. The mobile terminal 2 may be a mobile terminal having an access point (tethering) function.

  If the radar detector 4 can wirelessly communicate with the mobile terminal 2, it is possible to receive the distribution of the posting target information via the mobile terminal 2. It becomes possible for the radar detector 4 to notify the post target information or to make an alarm. Further, if the public control information is distributed, the public information can be reported by the radar detector 4 as shown in FIG. The radar detector 4 illustrated in the figure scrolls the distributed disclosure control information at the bottom of the map screen 62.

  Note that the driving support system may be capable of handling both the posted information of the first embodiment and the posted information of the present example. The post information of the first embodiment and the post information of the present example may be integrated to generate post target information. In this case, the post information generated by the mobile terminal 2 and the post information generated by the radar detector 4 may have different accuracy evaluations. For example, as for a contributor who has purchased and actually used the radar detector 4, it can be assumed that a person who attaches importance to an alarm function or the like and has abundant knowledge about traffic control. It is highly likely that such posted information by the poster can be evaluated with high accuracy.

  In this example, the accumulated points (FIG. 17) of the posted information list are used as the accuracy of the posted target information. In addition, the accuracy may be evaluated based on the past execution history of the traffic monitoring activity. For example, if there is a history of the same traffic monitoring activity in the past, a value of 120% of the accumulated points (a value of 20% increase) is set as the accuracy, or the history points are added to the accumulated points. It is also good. As the history point, a point reflecting the implementation frequency and the like is preferable. When judging the execution history of the past traffic monitoring activities, in addition to the use of existing traffic information, it is also possible to use the posting target information in the new arrival information area.

    The notification of the posted target information or the warning mode may be changed according to the vehicle information acquired by the OBD function, such as the speed of the vehicle. For example, in the case of a speed exceeding the speed limit, posted target information on mobile orvis and the like is very important.

(Example 3)
This example is an example in which post information is directly distributed based on the driving support system of the first embodiment. This content will be described with reference to FIGS. 17 and 45 to 47.

As the post information to be distributed, for example, the post evaluation point of the contributor is, for example, 8 points or more, and the post information that has not yet been reflected in the post target information, or the fluctuation of the monitoring position such as a police car that is being watched for Accordingly, there is posted information for which real-time properties are important.
FIG. 45 is a display example of posted information about a white motorcycle being watched. In the figure, on the map displayed on the touch panel 21 of the mobile terminal 2, the information pin 271 is displayed at the monitoring position corresponding to the posted information of the watched white motorcycle. The figure also shows a balloon display 275 displayed when the information pin 271 is tapped (touched). The balloon display 275 displays the date and time of posting, the activity content of the traffic monitoring activity related to the posted information, and the like. For posted information for which real-time property is important, a limit such as six hours is set for the displayed time, the mobile terminal 2 manages the time limit, and erases the information pin 271 as the time limit elapses. Good to do. The illustration of the information pin 271 may be changed depending on the type of the target traffic monitoring activity, and the display color and size of the information pin 271 may be changed depending on the degree of risk.

  Further, in the figure, a scroll display field 278 is provided at the bottom of the display screen of the touch panel 21. This scroll display field 278 is a display field of the posted information that does not include the monitoring position in the map area displayed on the touch panel 21 among the posted information distributed as described above. By providing such a display, it is possible to display posted information having a monitoring position in a distant place that is not included in the map area. As the distant range, a range such as 20 km can be set. It is also possible to selectively display distant posted information located in the traveling direction of the vehicle, distant posted information located on the traveling road, and the like. Note that the disclosure control information of FIG. 24 referred to in the first embodiment may be displayed in the scroll display field 278. In this case, the background color is changed between the disclosure control information and the posting information. It is advisable to devise ways to make it easier to discriminate between public regulatory information.

  As a message configuration when scrolling the posted information, for example, the configuration in FIG. 46 can be adopted. In the case of such a message structure, for example, "Yuppi (35) June 30, 10:30 [Speed control (radar)] Iwatsu-cho, Okazaki-shi, Aichi Prefecture Jupiter-mae I do it as usual. "Can be scrolled. As for the post experience value, a value that increases in proportion to the number of posts is good. For example, the number of correct postings and the overall evaluation shown in FIG. 3 may be adopted as the posting experience value. In order to increase the number of users who like postings, such as posting enthusiasts, it is also effective to give events such as giving a prize by awarding the top three posting experience values per year. It is also possible to provide the posting server with a program for selecting the top three posting experience values at the end of the year. Such an event provides an incentive for posting, and contributes to collection of more accurate posting information.

  Post information may be distributed automatically (for example, every 10 minutes) from the post server. As shown in FIG. 45, an update button 272 may be provided, and the distribution may be executed immediately in response to the operation of the update button 272. Further, the distribution of the posting information may be selectively performed only to desired users. This is because there is a user who does not want to distribute the post information whose accuracy is not sufficient.

In order to distribute the post information, a distribution file for each of 47 prefectures may be used. By using such a distribution file, for example, posted information in the prefecture can be collectively distributed to a user traveling in the prefecture. When distributing the distribution file for each prefecture, the distribution file for the adjacent prefecture may be simultaneously distributed in addition to the distribution file for the prefecture to which the current position belongs. Furthermore, the posting information included in the distribution file may be limited to posting information within 6 hours from the posting time (the time received by the posting server). The post information for one case may be, for example, the following contents.
・ Latitude and longitude: 34.794025 degrees, 137.1117188 degrees ・ Display period: 10:25 on June 6, 2012 to 16:25 on June 6, 2012 ・ Details of control Examples: Speed control (white bike)
・ Address information Prefectural example, municipal name in Aichi example, street address in Nishio city, example, No. 2 in XX town, detailed location and other landmarks (data may not be available)
Example: Road and comment from the intersection between JA in Nishihazu and the cedar pharmacy toward Koda (data may not be available)
For example, a place I often do. Be careful with the speed limit of 40km.
・ User information User name Example, Yuppi Post experience value Example, 121

In the mobile terminal 2 of this example, generation of post information can be started by a touch operation of the post button 273 of FIG. When the post button 273 is touched, a post page (not shown) is displayed. This posting page includes a text display of latitude / longitude, year / month / day / minute, address information when the post button 273 is touched, and operation means such as a rotating drum for selecting a type of traffic monitoring activity and the like. It is also possible to provide a picker view. For detailed locations and comments, it is better to input text. It should be noted that the detailed location and the comment may be allowed to be input so that the text input can be handled by a troublesome poster. If a comment or the like is passed, the post server may add a nifty comment.
The other configuration and operation and effect are the same as in the first embodiment.

  In this example, post information far away from the map area is scrolled to the bottom of the screen. Instead of this, as shown in FIG. 47, the post information whose monitoring position is located on the right side of the map area is scroll-displayed in a rectangular space 278R at the right end of the screen, and the monitoring position is located on the upper side. Post information may be scroll-displayed in the space 278U at the top of the screen. In this case, the direction of the distant posted information can be grasped in accordance with the scroll display position.

  As described above, specific examples of the present invention have been described in detail as in Examples 1 to 3, but these specific examples only disclose examples of the technology included in the claims. Needless to say, the scope of the claims should not be interpreted in a limited manner by the configuration or numerical values of the specific examples.
