Traffic signal control system based on vehicle-road cooperation

Abstract

The invention discloses a traffic signal control system based on vehicle-road cooperation. The system comprises an intersection vehicle monitoring module which is used for monitoring the vehicle data of vehicles on roads in all directions around an intersection driving into the intersection within a set time, an opposite vehicle counting module which is used for obtaining the maximum value of the data of the vehicles driving into the intersection within the set time on the roads in the two opposite directions to obtain the data of the vehicles in the driving directions, and obtaining the vehicle proportion according to the data of the vehicles in two mutually perpendicular driving directions, and a lamp time determination module which obtains the lamp time of two mutually perpendicular driving directions according to the product of the vehicle proportion and the basic lamp time, and sets the lamp time of the traffic light at the corresponding position of the intersection according to the lamp time of the two mutually perpendicular driving directions. According to the invention, the duration of the traffic light is adjusted by counting the vehicle passing condition at the intersection, so that the vehicles can smoothly pass through the intersection, the retention of the vehicles on the roads is reduced, and the traffic pressure is reduced.

Description

technical field [0001] The invention relates to the field of traffic management control, in particular to a traffic signal control system based on vehicle-road coordination. Background technique [0002] At traffic intersections, there will be signal lights in the direction of each intersection to direct the traffic. When directing traffic, the signal lights are divided into different colors. At present, there are three colors of red, yellow and green signal lights, and the red light means stop. Waiting, the green light means that the vehicle can pass, and the yellow light means the buffer when the red light and the green light are switched, so as to direct the traffic. When directing, by setting the time when the red light is on and the time when the green light is on, you can control The passing time of vehicles in all directions at the intersection, so as to achieve the purpose of traffic control. But in this way, the time of the traffic lights at each crossing is fixed,...

AI Technical Summary

Problems solved by technology

But in this way, the time of the traffic lights at each crossing is fixed, and the situation that will produce like this is, when there are many vehicles, the traffic will not be better directed, so that the vehicles stay on the road for too long Can not pass the intersection for a long time, thus causing traffic pressure
