Abstract

The invention discloses a single-point intersection traffic signal control method, and relates to the technical field of intelligent traffic control, and the method comprises the steps: obtaining lane traffic state information of lanes in two directions; the lane traffic state information comprises the driving speed of any vehicle at the current moment, the average headstock distance, the distance between any vehicle and a corresponding stop line, the number of waiting vehicles in front of any vehicle and the traffic flow; determining a switching period of the signal lamp; in each switching period, whether waiting vehicles exist on the lanes in the two directions or not is determined according to the lane traffic state information; when waiting vehicles exist on the lanes in the two directions, respectively calculating passing fitness functions of the two lanes according to the traffic state information of the lanes, the waiting time cost function of the lanes and the number of the vehicle queues; and controlling phases of signal lamps corresponding to the two lanes according to the passing fitness functions of the two lanes. According to the invention, the maximum delay of vehicles at the intersection can be reduced, and waste of lane occupancy is avoided.

Description

technical field [0001] The invention relates to the technical field of intelligent traffic control, in particular to a single-point intersection traffic signal control method. Background technique [0002] The intersection is a complex system, with the interweaving and diversion of traffic flow in all directions. The occurrence rate of starting, stopping, acceleration and deceleration of vehicles in the intersection area is significantly higher than that in other road network areas, which affects the overall continuity of traffic flow operation. Negative impact, resulting in traffic delays. Traffic lights are usually set at intersections. Reasonable control of traffic signals at intersections can improve the capacity of intersections, reduce vehicle delays at intersections, and effectively alleviate urban congestion. [0003] The current traffic signal control can be roughly divided into three categories: [0004] (1) Timing control. Timing control is mainly to divide a d...
