Coordinated optimization method for trunk lines with repeated releases in coordinated directions

Abstract

The present invention provides an arterial coordination optimization method for repeated release in the coordinated direction, draws a time-distance map on the basis of collecting the intersection signal control scheme, identifies the repeated release situation in the public cycle of the intersection, solves each situation based on the arterial coordination model, and finally compares Obtain the optimal scheme of arterial coordination; The arterial coordination optimization method of this kind of coordination direction repeated release is all by the present situation that the arterial coordination of current stage two-period, big and small cycle is judged and tested by human, arterial coordination of the present invention is to the cycle research of coordination intersection. Taking the public cycle into consideration, the multiple coordinated release phases in the public cycle are solved as the coordination phase, and the optimal trunk line coordination scheme is obtained in a cycle, which greatly improves the efficiency of trunk line coordination. At the same time, there are duplications at intersections Complicated conditions such as release and overlapping phases provide an efficient method for trunk line coordination and optimization.

Description

technical field [0001] The invention relates to an arterial coordination optimization method for repeated release in coordination directions. Background technique [0002] Urban traffic signal control is an important part of urban traffic. With the development of urbanization, the problem of traffic congestion is becoming more and more serious. The coordinated control of arterial and regional signals has become one of the main research contents in recent years because of its advantages in coordinated control. one. Especially the arterial coordinated control, because of its advantages of increasing the traffic speed of the arterial line, reducing the number of stops, reducing the phenomenon of running a red light and the probability of rear-end collision accidents, has been recognized by countries all over the world as "an effective way to reduce delays at intersections". [0003] "Repeated release" refers to the situation that a pass phase can pass in multiple stages within...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a trunk line coordination optimization method for repeated release in the coordination direction, aiming at the situation of "repeated release" in the coordination direction in the public cycle, the efficiency of the coordination optimization of the trunk line in the repeated direction is improved, and the workload of the letter control personnel is reduced. Solve the problem existing in the existing technology that the coordination of trunk lines requires personnel to adjust and optimize the test multiple times based on experience in the current complex situation
