Optimal configuration method of sensing interval when signal control intersection phase is green

Abstract

The present invention provides an optimal configuration method for signal-controlled intersection phase green-time sensing intervals. According to traffic flow, signal scheme time sections are divided, and based on non-motor vehicle and pedestrian crossing requirements, intersection vehicle traffic requirements, and traffic management requirements, each time period is determined. The green time induction interval of each phase stage is allocated and calculated. The present invention summarizes the minimum green hour demand and the maximum green hour demand in the signal phase time period, considers the green hour demand of non-motor vehicles and pedestrians crossing the street within the cycle time and the phase locking situation of the traffic control signal phase, and analyzes each phase in the time period Optimizing the configuration of the green light sensing interval in the phase, so as to effectively improve the utilization rate of the traffic signal at the intersection when it is green, improve the efficiency of intersection traffic, and alleviate the problem of traffic users.

Description

technical field [0001] The invention relates to an optimal configuration method of a signal control intersection phase green time sensing interval. Background technique [0002] With the rapid development of the national economy and the continuous improvement of people's material living standards, the number of urban motor vehicles is increasing year by year, and the problem of traffic congestion is becoming more and more serious. As an important node in the urban road network, intersections play a vital role in the transportation system. The traffic signal control can effectively optimize the traffic flow at the intersection and realize the orderly operation of the traffic at the intersection. [0003] Since the 1990s, major cities in China have successively adopted fixed traffic signal control systems. As urban traffic congestion continues to intensify, traditional fixed signal solutions can no longer adapt to the complicated traffic conditions at intersections. Therefore,...
