DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the present invention will be described with reference to the accompanying drawings. FIG. 1 is an overall configuration diagram of this system. In FIG. 1, the number of each facility may be plural depending on the installation site, the monitoring range of the roadside facility, etc., but here the configuration is not considered. Also, the input / output data in the figure shows only the data that is the basis of this system.
[0007]
The functional contents of the roadside equipment as the roadside infrastructure constituting the system and the in-vehicle device of the vehicle will be described. As roadside equipment, there are a vehicle detection equipment 1, a road database 2, an information processing equipment 3, and a reporting equipment 4 that cover a selected surveillance area where traffic congestion is likely to occur, and each has the following functions. . The vehicle detection facility 1 detects the position of the vehicle at a constant speed or less within the monitoring range. Database 2 is the alignment of the surrounding road including the monitoring range (positional relationship between the monitoring range and curves, intersections, etc.), the nature of each lane (running lane, overtaking lane, right turn lane), the length in the case of a right turn lane, and It has data related to entering and exiting vehicles such as nearby commercial facilities, parking lots, factories. The information processing facility 3 is an arithmetic device that performs integrated processing of the information in the vehicle detection facility 1 and the database 2, and its main function is to create information on traffic jams and their estimated causes. Although the reporting facility 4 varies depending on the system configuration, the traffic information generated by the information processing facility 3 through a variable display board 5 or communication is provided to the traffic information service or directly to the vehicle so that the driver can select a route. It is intended to prevent the growth of useful traffic jams.
[0008]
This system is intended for areas where traffic congestion is likely to occur, such as intersections, near parking lot entrances, factories, and roads facing shops, where there are many large vehicles. One example will be described with reference to FIG. FIG. 2 is an example of an intersection to which the present system is applied. In this example, the monitoring range is assumed to be the right turn lane 7 just before the intersection 6 and the overtaking lane 8 and the traveling lane 9 inside the intersection. Next, a mechanism for providing information to the following vehicle 14 will be described.
[0009]
The monitoring range in FIG. 2 is monitored by the vehicle detection facility 1 using visible light, infrared ray, laser, or radio wave, and a vehicle decelerated below a certain speed is detected within the monitoring range. The range is calculated and data is sent to the information processing facility 3. In the information processing facility 3, the traffic light and the data of the surrounding roads and facilities obtained from the database 2 indicate that the signal is blue, and no vehicle is staying near the intersection 6 of the driving lane 9 and the overtaking lane 8. Then, it is detected that the vehicle is staying in the right turn lane 7 and the overtaking lane 8 near the end of the right turn lane. At this time, since there are many vehicles 11 waiting for a right turn, the information processing apparatus 3 determines that the vehicle has started to stay in the tail of the overtaking lane beyond the right turn exclusive lane, and sends traffic jam range information to the reporting facility 4. Here, an example in which the reporting facility 4 directly provides information to the vehicle is shown. The vehicle 14 approaching the intersection 6 is informed that the overtaking lane 8 is congested in the vehicle 11 waiting for a right turn, so that the vehicle that goes straight ahead is changed to the driving lane 9 earlier, thereby suppressing the increase in traffic congestion. It becomes possible to do.
[0010]
FIG. 3 shows a situation where there is a parking lot entrance such as a large-scale commercial facility at the left turn, and a vehicle waiting to enter cannot stay left at the intersection and stays in the driving lane.
[0011]
The monitoring range shown in FIG. 3 is monitored by the vehicle detection facility 1 using visible light, infrared rays, lasers, radio waves, etc., a vehicle decelerated below a certain speed within the monitoring range is detected, and the congestion range is determined from the position of the low-speed vehicle. And data is sent to the information processing facility 3. In the information processing facility 3, the traffic light and the data of the surrounding roads and facilities obtained from the database 2 indicate that the signal is blue, the vehicle is not staying near the intersection 6 of the overtaking lane 8, and the driving lane 9 To detect that the vehicle is staying. At this time, the information processing equipment 3 takes into account that there is a parking lot 10 attached to a large-scale commercial facility at the left turn, and there are many vehicles waiting to turn left, so that the vehicle is staying in the lane 9 before the intersection. The traffic jam range information is sent to the display facility 5. The vehicle 14 approaching the intersection 6 is notified that the driving lane 9 is congested in the vehicle 12 waiting for a left turn, so that the vehicle that goes straight ahead is changed to the overtaking lane 8 at an early stage, thereby suppressing an increase in traffic congestion. It becomes possible to do.
[0012]
The road layout in the present system described above, for example, the road alignment, the number of lanes, the number of various facilities arranged on the road side, and the like are arbitrary, and are not necessarily limited to those illustrated. In addition, the reporting facility 4 and the display facility 5 as information providing devices are examples, and it goes without saying that the present invention is not limited to these.
[0013]
【The invention's effect】
As described above, according to the first aspect of the present invention, by detecting that a local traffic jam has occurred due to the circumstances of the road and surrounding facilities, and providing the information to the vehicle, compared to the conventional case There is an excellent effect that it is possible to effectively relieve congestion and to further improve convenience and safety on the road.
