Trunk coordination optimization method for repetitive releasing in coordinated direction

Abstract

The invention provides a trunk coordination optimization method for repetitive releasing in a coordinated direction. A time interval map is drawn based on collection of an intersection signal controlscheme; repeated release situations in a common cycle of the intersection are identified; all situations are solved respectively based on a trunk coordinated model; and then comparison is carried outfinally to obtain an optimal trunk coordination plan. According to the trunk coordinated optimization method, since the dual-cycle and large-small-cycle trunk coordination is determined and tested manually at the existing stage, the cycle study on the coordinated intersection by the trunk coordination provided by the invention takes the common cycle into consideration and multi-times coordinated releasing phase stages in the common cycle are used as coordinated stages and are solved, so that the optimal trunk coordination plan is obtained by circulation and thus the trunk coordination efficiency is improved substantially. Meanwhile, a high-efficiency trunk coordination optimization method is provided to avoid complicated situations of repeated releasing and phase overlap joint of the intersection.

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...

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
