Abstract

PROBLEM TO BE SOLVED: To make a driver restrain from speeding by calculating the average speed between two points on a road and directly giving warning of the speeding to the driver of a running vehicle which runs exceeding the speed limit. SOLUTION: Light beacons 3, 5 are installed at two points at the upstream side and the downstream side on a road. A vehicle ID to be transmitted from a VICS on-board equipment of the running vehicle 1 is detected by a vehicle ID detector 2, at the upstream side and a vehicle ID detector 4 at the downstream side. Speeding violation is determined by calculating the average speed of the vehicle 1 between two points by matching processing of the vehicle ID by means of a speeding determining apparatus 6. A warning message of the speeding is originated from the light beacon 5 to the VICS on-board equipment for the running vehicle 1 which is exceeding the speed limit. A warning message is displayed on a display of the VICS on-board equipment, and the speeding warning issued directly to the driver. A running vehicle dangerous in its average speed exceeding the speed limit is discriminated, and a warning with strong psychological restraining effects on speeding violation is performed at the same time.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a speed violation warning device for detecting and warning a speed violation of a vehicle, and more particularly to a speed violation warning device for detecting a speed from a traveling time in a certain section.

[0002]

2. Description of the Related Art The speed of a vehicle traveling on a road is detected,
2. Description of the Related Art For a vehicle running at a speed exceeding a speed limit, a warning message to reduce the speed is displayed on an electronic display panel or the like to suppress a speed violation.

FIG. 2 is a conceptual diagram of a conventional speeding warning device. In FIG. 2, a speed measuring device 8 is a device that measures the traveling speed of the vehicle 1 passing through a measurement point. The speed violation determiner 9 is a device that determines a speed violation from the measured traveling speed. The speed violation warning plate 10 is a warning plate that displays a message warning of a speed violation.

[0004] The speed measuring device 8 measures the speed of the measuring point of the vehicle 1 using radio waves or ultrasonic waves, and outputs a speed signal. The speed violation judging device 9 compares the speed signal with a violation reference speed stored therein to determine a speed violation, and outputs a speed violation signal. The speed violation warning board 10 displays a message to notify the vehicle 1 of the speed violation based on the speed violation signal.

[0005]

However, such a conventional speed warning device measures the instantaneous speed of a vehicle passing through a measuring point, and is necessary for the vehicle to travel in a certain section. It does not measure travel speed. Because it warns based on the point speed measured instantaneously at one point, it is not possible to distinguish between a temporary minor speed violation and a severe speed violation that runs continuously at the violation speed. However, only the same warning message could be displayed, and the effect of suppressing speeding for the driver was insufficient. In addition, since warning messages are displayed on the warning display panel on the road, when multiple vehicles are driving, the driver is not able to clearly understand which vehicle the warning message is for, and the driver has a psychological suppression effect. The present invention, which is small, is intended to solve the above-described inadequate suppression effect, measures the travel time of a traveling vehicle in a relatively long section, determines a speed violation from this travel time, and determines the downstream speed of the section. It is an object of the present invention to suppress a severe speed violation in which the average speed in a certain section exceeds the speed limit by warning a speed violation at a point on the side.

[0006]

In order to solve the above-mentioned problems, according to the present invention, a speed violation warning device is installed at two points of a vehicle ID detector, and the travel time of the vehicle between the two points is measured. Then, a speed violation in which the average speed of the section exceeds the speed limit is determined, and a speed violation warning device on the downstream side of the section directly transmits a speed violation warning message to the vehicle.

[0007] With this configuration, a speed violation can be detected and warned based on the section travel speed, and a warning message is directly sent to a serious speed violation vehicle whose average speed exceeds the speed limit. Can be sent to give a strong psychological warning.

Hereinafter, an embodiment of the present invention will be described with reference to FIG.
This will be described in detail with reference to FIG.

(Embodiment) In an embodiment of the present invention, an upstream vehicle ID detector and a downstream vehicle ID detector for detecting a vehicle ID via an optical beacon are provided at two points on a road,
Based on the vehicle IDs detected by the vehicle ID detectors at the two points, an average speed between the two points is determined to determine a speed violation,
This is a speed violation warning device that transmits a speed warning message directly to a vehicle via an optical beacon on the downstream side.

FIG. 1 is a conceptual diagram of a speed warning device according to an embodiment of the present invention. In FIG. 1, a vehicle 1 is a VI
This is an automobile equipped with a CS device and an optical communication device.
The upstream vehicle ID detector 2 is a device that receives the vehicle ID of the vehicle 1 via the optical beacon 3 and detects the vehicle ID. The optical beacon 3 performs optical communication with the vehicle 1 and
D. The downstream vehicle ID detector 4
This is a device that receives the vehicle ID of the vehicle 1 via the optical beacon 5 and detects the vehicle ID. The optical beacon 5 is a device that performs optical communication with the vehicle 1 and receives a vehicle ID. The speed violation determining device 6 is a device that determines an average speed from the vehicle IDs from the upstream vehicle ID detector 2 and the downstream vehicle ID detector 4 and the section travel time of the vehicle, and determines a speed violation.

The operation of the speed warning device according to the embodiment of the present invention will be described with reference to FIG. An optical beacon 3 and an optical beacon 5 are installed at two points about 100 m apart on the upstream and downstream sides of the road. Each of the optical beacons 3 and 5 has a communicable area having a diameter of several meters and a vehicle in the area and several Mb.
Bidirectional optical communication can be performed at a speed of about ps. The vehicle 1 is equipped with an on-board VICS device and includes an optical communication device. The VICS in-vehicle device is a traffic support device that can acquire traffic information and transmit various types of information from a vehicle to a road facility using wireless communication and optical communication. In the case of performing optical communication, an optical beacon provided on the road side can be used to transmit and receive data of about several kilobytes in a time of about several hundred ms in which a vehicle passes through a transmission / reception beam of the optical beacon.

When the vehicle 1 passes through the communicable area of the optical beacon 3 on the upstream side, the upstream vehicle ID detector 2 inquires the vehicle 1 about the vehicle ID. Vehicle 1 is the vehicle ID
If so, the vehicle ID is answered (FIG. 1).
If there is no vehicle ID, the upstream vehicle ID detector 2
Issues a new vehicle ID to vehicle 1. Vehicle I
D is not unique to the vehicle 1, but is to give a circulating number or the like to the vehicle from the VICS system side. The upstream vehicle ID detector 2 transmits to the speed violation judging device 6 data in which the vehicle ID and the passing time of the vehicle 1 are combined.

When the vehicle 1 passes through the communicable area of the optical beacon 5 on the downstream side, the downstream vehicle ID detector 4 inquires the vehicle 1 about the vehicle ID. Vehicle 1 is a vehicle ID
(Fig. 1). The downstream vehicle ID detector 4 transmits to the speed violation judging device 6 data in which the vehicle ID and the passing time of the vehicle 1 are combined.

The speed violation judging unit 6 searches for a vehicle ID that matches the vehicle ID detected on the downstream side from the vehicle IDs detected on the upstream side. Since at most about 10 vehicles are traveling between the upstream and downstream points,
Search in a very short time. The travel time between the upstream point and the downstream point of the vehicle corresponding to the vehicle ID is determined from the upstream optical beacon passage time and the downstream optical beacon passage time of the matching vehicle ID. The average speed of the vehicle 1 is calculated from the travel time and the section distance and compared with the speed limit. If the average speed exceeds the speed limit, it is determined that a speed violation has occurred and the speed violation warning device 7 is notified.

The speed violation warning device 7 receives the speed violation determination notification and transmits a message warning the speed violation together with the vehicle ID to the vehicle 1 via the optical beacon 5 (FIG. 1).
). Since these processes are completed in about 10 ms, it is possible to transmit a warning message before the vehicle 1 passes through the communication area of the optical beacon 5.

The vehicle 1 identifies the warning message with its own vehicle ID and displays the warning message on the display device of the VICS vehicle-mounted device. At the same time, a warning sound or voice message alerts the driver. Since the warning message is displayed directly on the display device of the VICS on-board unit mounted on the vehicle 1, the driver certainly realizes that his or her vehicle has exceeded the speed limit. The effect of psychological deterrence is greater than that displayed on a signboard on the road, and the driver is allowed to travel within the speed limit.

In this embodiment, two upstream and downstream sides are used.
Although the example in which the average speed of the vehicle is obtained between the points and the warning of the speed violation is issued has been described, the use of the optical beacon at three or more points can be easily realized. Since a large number of optical beacons are installed at an appropriate distance, obtaining an average speed between two adjacent optical beacons and issuing a speed violation warning is not sufficient for the optical beacons at each position. The equipment has the function of the upstream and the function of the downstream,
The same processing as described above may be performed for each section.

As described above, in the embodiment of the present invention,
The speed warning device is connected to the upstream vehicle I for detecting the vehicle ID.
D detector, downstream vehicle ID detector, and both vehicles I
The travel time between two points is measured from the vehicle ID detected by the D detector, and a speed violation determiner that determines a speed violation based on the travel time, and a speed violation warning is given directly to the vehicle based on the result of the speed violation determination. And a speed warning device for transmission.
Send a speed warning message from the optical beacon,
Since a warning of a speed violation is issued directly to the driver via the VICS vehicle-mounted device, a warning can be directly issued to the driver who has a serious speed violation, and the speed violation can be strongly suppressed.

[0020]

As described above, according to the present invention, the speed warning device is optically communicated with the optical beacon installed on the upstream side of the road and the running vehicle via the optical beacon, and the vehicle ID is transmitted.
