Optimal configuration method for signal control intersection phase green light time induction interval

Abstract

The invention provides an optimal configuration method for a signal control intersection phase green light time induction interval. According to a traffic flow, a signal scheme time period is divided,and the green time induction interval of each phase stage in each time period is subjected to distribution calculation on the basis of non-motor vehicle and pedestrian street crossing requirements, intersection vehicle passage requirements and traffic management requirements. By use of the method, minimum green light time requirements and maximum green light time requirements in the signal phasetime period are summarized, the street-crossing green light time requirements of non-motor vehicles and pedestrians in periodic time and a locking situation of a traffic control signal phase stage areconsidered, the green light time induction interval of each phase stage in the time period is subjected to optimal configuration, so that a green light time use ratio of the interaction traffic signal is effectively improved, intersection passage efficiency is improved, and a traffic user problem is alleviated.

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,...
