Abstract

PROBLEM TO BE SOLVED: To provide a traffic monitoring system effectively using facilities, and capable of performing traffic monitoring not only speeding but also over many items, and reducing costs of a device to be loaded on a vehicle.SOLUTION: A sign monitoring device transmits road traffic regulation information such as speed restriction, parking prohibition, one-way traffic, and no entry, and a vehicle information declaration device loaded on a vehicle transmits own vehicle identification information and violation information to the sign monitoring device when violation decision means determined that an own vehicle violates road traffic regulation. Also, the violation decision means may be installed at a sign monitoring device side.

Description

  The present invention relates to a traffic monitoring system, and more particularly to a traffic monitoring system that enables traffic monitoring to be performed over many items, not just speed violations.

The majority of traffic accidents are often caused by exceeding speed limits, especially when many serious accidents such as slip accidents and rear-end collisions on highways and bypass roads with relatively high speed limits are caused by exceeding speed limits. There are many.
Therefore, various traffic monitoring means have been taken conventionally. For example, an automatic speed violation control device in which a speed detection radar and a vehicle shooting camera are set on an arched structure on a road is known. This irradiates a traveling vehicle with high frequency radio waves from the front, receives the reflected signal, and uses the Doppler effect to increase the frequency of the received radio waves according to the traveling speed of the vehicle. It is to detect. Further, when the detected speed exceeds the regulation value, the speed violation is controlled based on the photograph of the license plate of the vehicle and the photograph taken by the driver.
Patent Document 1 proposes a means for increasing the probability of specifying a vehicle by photographing not only the license plate in front of the vehicle but also the license plate in the rear of the vehicle. This measures the speed of the approaching vehicle, etc., and when the speed exceeds the specified value, activates the camera and takes a license plate from the front of the vehicle, and after a predetermined time calculated from the measured vehicle speed, Again, aim at the back of the vehicle. That is, if the shooting screen from the rear calculates the timing suitable for shooting the license plate behind the vehicle and releases the shutter of the camera, even if the front license plate shooting fails, This makes it possible to check the vehicle.
However, if the license plate is still dirty with mud, intentionally removed, or covered with a cover that prevents shooting, the vehicle may not be accurately identified.

As means for solving such a problem, for example, Patent Document 2 proposes a method that does not require camera photographing as vehicle specifying means.
FIG. 6 is a schematic configuration diagram of a vehicle speed monitoring system proposed in Patent Document 2. This vehicle speed monitoring system is composed of a vehicle speed monitoring device 61 installed on the side of the road and a vehicle-mounted speed violation reporting device 62 mounted on the vehicle. An antenna 64 and a speed violation vehicle information generation unit 65 are provided. The in-vehicle speed violation reporting device 62 includes an antenna 66, a wireless transmission / reception unit 67, a vehicle device control unit 68, a travel speed measurement unit 69, a warning sound generation unit 70, a display unit 71, a vehicle specific information recording unit 72, a speed violation. An information recording unit 73 is provided.
The detailed operation and control method of the vehicle speed monitoring system configured as described above are disclosed in Patent Document 2 and will be briefly described here. First, the vehicle speed monitoring device 61 transmits speed restriction information built in the memory at a preset time interval. In the in-vehicle speed violation reporting device 62, this signal is received by the wireless transmission / reception unit 67 and compared with the traveling speed information of the own vehicle detected by the traveling speed measuring unit 69. Overspeed information is attached to specific data such as a vehicle number, a vehicle manufacturing number, a vehicle manufacturer name, a vehicle owner name, and a vehicle owner address stored in 72, and the wireless transmission / reception unit 67 passes through an antenna 66. To the vehicle speed monitoring device 61. The in-vehicle speed violation reporting device 62 also includes means for generating a warning sound to the driver when the speed violation is determined and displaying the fact on the display unit 71 to prompt speed reduction. ing.
The vehicle speed monitoring device 61 that has received the speed violation report from the in-vehicle speed violation reporting device 62 reports the acquired unique data and speed violation information to the related authorities such as the nearest police, and later on the violation vehicle. Appropriate notices will be sent to the owners.
As described in Patent Document 2, such a method must legally obligate the vehicle to be provided with a speed violation reporting function. Obviously, the clearance rate in the event of a violation will be greatly increased, and it is clear that it will greatly contribute to the suppression of traffic speed violations and the reduction of traffic accidents.

The transmission / reception device 11, the identification information memory device 12 that records vehicle identification information such as its own license plate number, the traveling speed detection device 13 that detects the speed of the own vehicle, and the traffic regulation transmitted from the sign monitoring device 1 Violation determination unit (means) 14 that obtains information and determines whether or not the own vehicle violates traffic regulations, and if it is determined that the vehicle violates traffic regulations, the vehicle identification information and the violation Violation notification means for transmitting information to the sign monitoring apparatus 1 via the wireless transmission / reception apparatus 11 is provided. The traffic information management center 3 manages violation information on vehicles and the like reported from the sign station device 1. The violation determination unit 14 includes a ROM 15 and a RAM 16 for storing programs and data necessary for determining violations. The violation notification means is implemented by the violation determination unit 14, the ROM 15, the RAM 16, and the wireless transmission / reception device 11, and further includes a display 17 for notifying the driver of the violation. In addition to the own vehicle license plate information, the identification information memory device 12 includes a vehicle body number, a vehicle manufacturing number, a vehicle manufacturer name, a vehicle owner name, a vehicle ownership, as described in Patent Document 2. Specific data such as a person's address can also be included.

According to the traffic monitoring system configured as described above, it is possible to monitor not only speed violations but also various traffic regulation violations as described below. The speed violation monitoring in this embodiment can be referred to because it employs almost the same mechanism as the method disclosed in Patent Document 2, but in the traffic monitoring system of the present invention, the speed limit information ( It is possible to monitor not only the speed regulation information) but also other road traffic regulation contents defined in the vicinity of the road. Therefore, in this example, in addition to the speed limit information, as an example, a restriction information memory device 6 storing restriction information such as parking prohibition, one-way traffic, entry prohibition and the like, and necessary items of the road traffic regulation contents are displayed. A display unit 5 is provided, and necessary information for the road traffic regulation content is transmitted to the vehicle information reporting device 2 mounted on the vehicle passing through the vicinity via the wireless communication device 4.
On the other hand, the vehicle information reporting apparatus 2 that receives these information includes a violation determination unit 15, and the vehicle violates these regulations based on the traffic regulation information received from the sign station apparatus 1. Determine whether or not. For example, the speed is detected by the traveling speed detection device 13 during traveling, and compared with the regulated speed information transmitted from the sign station device 1, and when the speed exceeds the regulated value, the speed excess information is identified. The vehicle identification information read from the information memory 12 is transmitted to the sign station device 1 via the wireless transmission / reception device 11.

The present invention is not limited to the above embodiments, and various modifications can be made. For example, as shown in FIG. 2, by providing the sign monitoring device 1 with a function for determining traffic regulation violations, the configuration of the vehicle information reporting device 2 that needs to be installed in each vehicle can be simplified and the cost can be reduced. Can do. That is, FIG. 2 is a block diagram showing a modified embodiment of the traffic monitoring system of the present invention. The same components as those in FIG. In this example, the sign monitoring device 20 includes a violation determination device 21, and the vehicle information reporting device 30 is characterized in that a control unit (CPU) 31 having a simple configuration is provided instead of the violation determination unit. In the traffic monitoring system configured as described above, a question signal is transmitted regularly or constantly from the sign monitoring device 20, and the vehicle information reporting device 30 that has received the question signal receives the speed information of the vehicle at that time, Return direction information and vehicle identification information. The sign monitoring device 20 determines whether or not there is a traffic regulation violation based on these return signals, and if there is a violation, transmits a warning signal to the vehicle on which the vehicle information reporting device 30 is mounted. The traffic information management center 3 is notified of the information.
In the vehicle information reporting device 30 that has received the warning signal, the driver is notified of this by voice or display. In order to transmit the alarm signal only to the corresponding vehicle, it is appropriate to adopt an individual selective calling method using identification information as a selective calling signal. According to this configuration, there is an effect of reducing the cost of the vehicle information reporting apparatus 30 that needs to be mounted on a large number of vehicles, which is convenient for spreading these systems.
If the sign monitoring apparatus 1 is provided with a function for determining traffic regulation violations and the sign monitoring apparatus 1 is also provided with a function for detecting the speed of a moving vehicle passing therethrough, the vehicle information reporting apparatus 30 is provided. From there, it is only necessary to transmit only the vehicle identification information. At this time, the speed detection means by the sign monitoring device 1 may be based on a conventionally known radio wave Doppler effect, or depending on the time required for the vehicle to pass between metal movement sensors (coils) embedded at predetermined intervals in the road. Various means such as speed detection can be used. Even in this example, it is not necessary to photograph a vehicle or the like.

  FIG. 3 is a schematic configuration diagram of a vehicle information reporting apparatus according to another embodiment of the present invention. The vehicle information reporting apparatus 40 shown in this example is characterized in that it includes a memory device (hereinafter referred to as a vehicle inspection / tax payment information memory) 41 that stores vehicle inspection information of the own vehicle and / or tax payment information related to the vehicle. is there. That is, the vehicle inspection / tax payment information memory 41 stores necessary information such as vehicle inspection validity period information, compulsory insurance participation information, and maintenance inspection information of each vehicle. These information records are also preferably required by legal means. When a question signal for returning vehicle inspection / tax payment information is transmitted from the sign monitoring device 20 described above, the vehicle information reporting device 40 that has received the signal sends the vehicle inspection / tax payment information memory 41 together with the vehicle identification information. The information read from is returned. Based on these return signals, the sign monitoring device 20 determines whether the vehicle inspection is within the valid period and whether tax payment has been made. If the period has expired or has not been paid, A warning signal is transmitted to the vehicle on which the corresponding vehicle information reporting apparatus 30 is mounted, and the information is notified to the traffic information management center 3. Similarly, in the vehicle information reporting device 30 that has received the warning signal, the driver is notified of this by voice or display.

FIG. 4 is a schematic configuration diagram showing another embodiment of the traffic monitoring system according to the present invention, and shows an example in the case of monitoring the intrusion monitoring of the vehicle into the intrusion prohibited area, the reverse running of the one-way road, or the like. Is. For example, when the sign monitoring device 50 holds traffic prohibition information for one-way traffic prohibition and one-way traffic, the vehicle information reporting device 51 is equipped with a GPS position detection device, a self-contained navigation device comprising a gyroscope and a speed sensor. Keep it. In this case, a car navigation device using a normal GPS receiver may be used. When the intrusion prohibition area or the one-way prohibition information transmitted from the sign monitoring device 1 is received, the traveling direction of the own vehicle is detected, and whether the regulation information and the traveling direction of the own vehicle are compared. It is possible to determine whether or not there is a violation in the sign monitoring apparatus 1 by returning the traveling direction information to the sign monitoring apparatus 1. When the vehicle itself makes a determination, more accurate determination can be made by adding information indicating the entry prohibition direction or the one-way restricted direction (direction) from the sign monitoring device 1.
Further, since the vehicle information reporting device 51 of the present invention is equipped with the wireless transmission / reception device 11, it is configured to effectively utilize these to notify that an emergency vehicle 52 such as an ambulance or patrol car has approached. You can also That is, as shown in FIG. 4, a signal transmitted from the emergency vehicle 52 is directly received by the wireless transmission / reception device 11 of the vehicle information reporting device 51, or the vehicle is transmitted via the sign monitoring device 1 or the traffic information management center 3. There is a method of notifying the information reporting device 51 of emergency vehicle approach information. Further, it is possible to change the traffic regulation contents of the sign monitoring device 1 by a signal transmitted from the emergency vehicle 52. For example, it is also useful for further accident prevention to perform a quick closure of a road leading to a traffic accident or fire occurrence site, a speed limit instruction, etc. by radio.

FIG. 5 is a schematic diagram of a traffic monitoring system showing an embodiment when parking violation is monitored according to the present invention. That is, in the sign monitoring device 1 (or 20, 50), a road sign indicating parking prohibition is displayed on the display unit 5, and when a parking information request signal is transmitted from the vehicle information reporting device 2, it responds to the request. A parking prohibition signal is transmitted from the sign monitoring device 1. That is, when the vehicle is stopped, a parking information request signal is intermittently transmitted from the vehicle information reporting device 2, and when the sign monitoring device 1 receives the vehicle identification information signal included in this signal, the parking and continuation of parking is continued. Time counting is started and the time for which the parking information request signal is continuously received is integrated. And when the continuation time passes predetermined time, it judges that parking is prohibited and notifies that to the traffic information management center. Alternatively, when the vehicle information reporting apparatus 2 includes a violation determination means, a signal indicating that parking is prohibited is periodically or intermittently transmitted from the sign monitoring apparatus 1, and the vehicle information reporting apparatus 2 It may be determined that it is a parking prohibition violation on the side and notified to the sign monitoring apparatus 1.
At this time, the sign monitoring device 1 records the date and time information at that time and notifies the traffic information management center 3 of the information. It is preferable that the signal only reaches the area where parking is prohibited, but if it is difficult to accurately limit the range, for example, a leaky coaxial cable 53 is laid in the area where parking is prohibited. The restriction signal output from the sign monitoring device 1 can be radiated as a weak signal from the leaky coaxial cable 53. The leaky coaxial cable can radiate or receive weak radio waves depending on the characteristics of its structure (can be transmitted to the sign monitoring device 1 via the cable), so that the reach of radio waves can be accurately limited. It is. In addition to using a leaky coaxial as a method for transmitting a parking prohibited area signal by limiting the area, it is also possible to arrange terminal devices that transmit and receive ultrasonic signals, infrared signals, etc. in the area. Can do.

The present invention can be variously modified in addition to those described above, and the method proposed in Patent Document 2 can be used in combination. For example, a violation determination means is provided on both the sign monitoring device side and the vehicle information reporting device side, and whether the violation is determined on the sign monitoring device side or on the vehicle information reporting device side depending on the traffic regulation item to be monitored Can be selected, and more accurate determination and monitoring can be performed by comparing the monitoring results of both to determine violation. Also, the vehicle information reporting device must be provided with violation information recording means as described in the violation patent document 2 and legally obliged to keep a record for a certain period like a flight recorder of an aircraft equipment. Is also possible. In addition, the ETC system (Electronic Toll Collection Systems), which has recently become widespread, and the ITS (Intelligent Transport System), which has been researched, are incorporated into these systems. Implementation is also envisaged.
Furthermore, the processing for realizing the traffic monitoring system according to the present invention can be programmed according to an OS that can be controlled by a computer. It is possible to control by the same processing method by installing the program in a device having the same OS and having a computer function. If such a program is recorded on a recording medium, the program can be operated anywhere by carrying the recording medium. As a recording medium for storing the program, a semiconductor medium (for example, ROM, nonvolatile memory card, etc.), an optical medium (for example, DVD, MO, MD, CD, etc.), a magnetic medium (for example, magnetic tape, flexible disk, etc.) ) Or the like.
