Intersection traffic road condition detection system for intelligent control of traffic signals

Abstract

The invention relates to the field of intelligent traffic management, in particular to an intersection traffic road condition detection system for intelligent control of traffic signals. A road condition monitoring device detects the queue length of lanes coming from each direction of intersections, a comparison module compares the queue length of the lanes coming from different directions and generates a comparison result, and a signal optimization module generates traffic signal control information suitable for a current traffic condition according to the comparison result. A traffic signalcontroller adjusts the setting time of the traffic signals of traffic lights at the intersections according to the traffic signal control information, the time proportion of green lights of the traffic lights corresponding to road direction with longer queue lengths is increased, the setting time of the traffic lights is optimized, and the occurrence of traffic jams caused by long queue times is reduced.

Description

technical field [0001] The invention relates to the field of road traffic, in particular to an intersection traffic condition detection system for traffic signal intelligent control. Background technique [0002] With the development of society, there are more and more vehicles on the road, and the road traffic conditions are more and more complicated. Generally, traffic lights are set at intersections, and vehicles on the road pass according to the instructions of the signal lights. Traffic lights are generally set at intersections facing the direction of vehicles. Through the alternate work of traffic lights, vehicles can pass through intersections in an orderly manner. The time setting of traffic lights is generally controlled by traffic signal controllers. [0003] However, the traffic flow of roads with different destinations at intersections is different, and the time setting of traffic lights is generally fixed. There are some destination vehicles that rarely cause en...

Problems solved by technology

[0003] However, the traffic flow of roads with different destinations at intersections is different, and the time setting of traffic lights is generally fixed. There are some destination vehicles that rarely cause endless waste of green light time, while many of the destination vehicles have queuing time. Too long, resulting in insufficient green light time and causing traffic jams
