Definitions
- the invention relates to a remote query system for providing Information about traffic conditions, especially traffic jams, denser Traffic, fog, slippery, ghost drivers, on expressways.
- a disadvantage of the known traffic jam systems is that they are not can react flexibly to the current traffic situation, as the time of the day Origin until a traffic jam is reported and until the Traffic jam reports are often very long.
- Telephonic remote access systems are known which are used, for example, for Querying account balances or making bookings at Telephone banking or order by telephone in mail order.
- the user is made of predeterminable with an announcement text Announcement text blocks are instructed for use or the Desired information transmitted, the user his commands outputs coded using the keypad of his phone using the multi-frequency method.
- remote telephone inquiry systems are known, their operation and control via pure voice signals, which a Able to evaluate the speech recognition unit of the remote access system is.
- the invention has for its object to provide a traffic jam system To make available which information about the Is able to provide traffic conditions and this to any Makes times available for those interested.
- the task is solved by a remote inquiry system for the provision of Information about traffic conditions on expressways with a Input element, which user information is able to recognize, and an output element, which predeterminable text modules compile and the user as perceivable by this Is able to transmit signal.
- the input element takes the User information received via a reporting channel, information about Location and type of traffic disruption, together with information be stored in a database about the time of the call. Farther it takes from the user information that is received via a query channel, Information about the route of interest, what the Remote query system a database query for the route in question carries out, and the determined information about the Traffic conditions communicated to the user through the output element will.
- the remote query system according to the invention works mainly on a telephone basis, with callers using the reporting channel the database provide with information and this again via a query channel can retrieve. In addition, there is also an online query option provided on the Internet.
- the remote query system guides the user telephone access with an announcement from predeterminable Announcement text modules for use. These announcement texts are the Caller transmitted acoustically through the output element. Likewise, it transmits the information that the caller has when querying the Traffic conditions from the database.
- the input element of the remote query system has a Speech recognition unit based on the natural language of the Caller recognizes certain keywords and uses them in converts usable information, which is then converted into the Database or with the help of a database query is feasible. These keywords are preferably all Motorway and federal road names, names of localities, as well as junctions and motorway junctions.
- the Speech recognition unit the different types of traffic disruption, e.g. Traffic jam, heavy traffic, fog, slippery, ghost driver, identify can.
- the remote query system requests preferably the user in turn to enter only this Keywords on. If the system did not recognize a keyword, then so it prompts the user to enter it again.
- Traffic conditions are queried online via the Internet preferably using a suitable screen mask, which the User to enter the route of interest at his terminal prompts.
- the remote control system offers ease of operation the user preferably the relevant keywords Characterize the route in a list from which the User only needs to select. It can also be a street map on which the user is interested Select route section by clicking or on the current one Traffic disruptions are already optically marked.
- the information formed from the keywords about the location of a traffic disruption or one that interests the user is stored in the database or queried from the database.
- the database can consist of a list of all motorway and federal road segment segments, characterized by starting and ending points such as junction (s) and / or motorway junction or town. These track segments are each with the property Traffic jam "," heavy traffic ",” smoothness "etc. respectively no malfunction ".
- the number of messages received for the relevant route segment and their time is preferably stored. This facilitates an assessment of the relevance of the existing malfunction messages.
- Information that is older than a specified time interval for example, half an hour or an hour, are preferred automatically deleted from the database.
- a specified time interval for example, half an hour or an hour
- the deletion of a fault message can also be controlled by the user the message that a reported for a certain route Fault no longer exists.
- a Deletion notification to be verified multiple times to actually get the To delete the relevant fault entry.
- the database is filled by callers who use the remote access system Provide traffic information.
- traffic information Currently many drivers have a mobile phone with which they can easily Remote query system can report malfunctions. Such a call goes thereby via a reporting channel with the remote access system.
- Corresponding can provide information about the traffic situation via a query channel can be called up by telephone. Message and query channel can either by two different phone numbers or by an input query be distinguished. Furthermore, access to the query channel is via the internet provided.
- the caller When a call arrives via the reporting channel, the caller is first asked to indicate the street name, direction of travel, location and type of traffic disruption, preferably by specifying the relevant junctions or motorway junctions.
- the speech recognition unit converts this information into computer-usable information about the disrupted route.
- the computer determines on the basis of the direction of travel and the name of the motorway or on the basis of the respective connection points or intersection points in which route segment the fault is located.
- the corresponding route segment is then named in the database Traffic jam "or the respective fault.
- the time of the call is also saved.
- the remote query system preferably plays that of the Speech recognition unit recognized and converted information, composed of saved text modules, the caller with the help the starting element again and takes it only after it Confirmation in the database. This confirmation that the speech signals recognized correctly, for example by pressing a button multi-frequency coded or also by voice input.
- An over Incoming calls to the reporting channel are preferably free of charge.
- the user can inquire about the road conditions on certain routes with a call coming in via the query channel or via the Internet.
- the remote query system uses the output element to request street names and directions and, if applicable, the planned route section.
- the speech recognition unit determines the keywords from the user's speech signal and converts them into information that can be used by the computer. With this information, the assignment to a route section stored in the database is made, which can consist of one or more route segments. These route segments are each with the characteristic Disorder "or no disturbance ".
- the remote query system preferably offers that User to determine an undisturbed evasion route and notify him these on request.
- the message transmitted to the caller is composed of several announcement text modules, for example a basic module such as On the ... between ... and ... is reported. ", Whereby the gaps in this basic module with the keywords also stored as announcement text modules e.g. A 5, junction XY, a traffic jam ". If there is no disturbance on the queried route, this is communicated in a standard message. If the planned route could not be identified by the speech recognition unit, the caller is preferably requested to enter it again.
- a basic module such as On the ... between ... and ... is reported. ", Whereby the gaps in this basic module with the keywords also stored as announcement text modules e.g. A 5, junction XY, a traffic jam ". If there is no disturbance on the queried route, this is communicated in a standard message. If the planned route could not be identified by the speech recognition unit, the caller is preferably requested to enter it again.
- the remote inquiry system provides a means Providing information about traffic conditions Available, which is flexible to existing and rapidly changing Is able to react to traffic conditions. It also offers the Possibility to selectively select these traffic conditions at any time To query routes. This enables the user to quickly and individual route planning regardless of the official Traffic news on the radio.
- FIG. 1 shows in the form of a Block diagram of the basic function of the remote access system.
- the core of the remote query system is the database 3, in which Information about traffic conditions on individual Track segments are saved. Every track segment is through its start and end point, if necessary also the street number, clearly defined and marked with the characteristic whether a Traffic disruption is present, preferably also the type of disruption is specified.
- the remote query system obtains its information about traffic conditions, and thus those stored in database 3 Data, mainly from reports from private users, that this Information about a reporting channel, left side of Figure 1, by telephone to transfer. Additional information, e.g. official information of Traffic services or the police can also go directly to the database be included, which is not shown here.
- this shows Remote query system an input element 1, on which by telephone can be accessed by dialing a specific phone number to pass information via the reporting channel or via the Query channel, right side of Figure 1, request information.
- On the Query channel can also be accessed online via what shown here in dashed lines to distinguish it from telephone access is.
- the remote query system has an output element 2, which guides the user to operate the system. With telephone Access to the reporting or query channel becomes audible to the user performed by the playback of predeterminable announcement texts.
- a suitable screen mask which preferably is self-explanatory.
- the input unit has a speech recognition unit which is used for Recognition and conversion of voice signals into computer usable Information serves.
- the input unit determines when a call arrives determined from the natural speech signal via the message channel Keywords that unambiguously assign a Traffic information for a specific route segment or Allow chain of track segments. Likewise, upon receipt of a Call the route of interest determined via the query channel and in converted usable information. These keywords are sensibly the names of localities, junctions, Expressways and certain traffic disruptions.
- the Speech recognition unit can specifically learn these keywords to have.
- the information coming in via the reporting channel is stored in the database 3 involved. Locations are used to identify the person (s) Route segments, the indication of the disturbance to change the Disturbance feature. In addition, the time is displayed with the fault characteristic the message filed in the database. Via the reporting channel can a user may also be notified that a previously reported malfunction is no longer available. If such a message is received, the fault characteristic of the route in question is set to "no fault" set.
- the messages received via the query channel become Identification of the route of interest analyzed.
- the filters Speech recognition unit 4 as in the case of the fault message via the Message channel certain keywords from the natural speech signal and converts this into information with which a database query can be carried out.
- a request is received via the Internet a conversion into usable data is not necessary, here it can Input element 1 without the aid of speech recognition 4, therefore, directly access database 3.
- the fault characteristic is one or more in the query channel Route segments queried from the database. In doing so, a Disturbance feature only released for playback if it is sufficiently relevant, e.g. multiple times by independent users has been entered, represents official police information and / or is not too old.
- the transmission of information to the user in the query channel is acoustically by the output element 2 like the user guidance predetermined announcement text modules that lead to an adapted speech signal be compiled, or on the Internet, making the Information is displayed on the screen by the user, accomplished.
