Problems solved by technology
[0003] At present, some research institutes and enterprises at home and abroad have made contributions to the optimization of intersection signals, and some developed countries or developed cities have also adopted different optimized signal systems, represented by SCOOT, TRANSYT, SCATS and ACTRA systems internationally. It is difficult to establish a unified model for the system, and the construction cost remains high. The implementation is greatly restricted by engineering factors and professional level, so it is also difficult to solve the traffic congestion in the urban road network

The invention discloses an urban pulse traffic signal control system and method. The main control idea of the urban pulse traffic signal control system and method is that trunk line green wave controlis taken as the principle thing and self-adaptive control of branch line intersections is taken as the auxiliary thing, and includes a signal control and optimization method of point, line and planeof urban intersections. The principle of the urban pulse traffic signal control system is different from other urban signal systems, and belongs to optimized construction based on bionics.
Description
technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to an urban pulsating traffic signal control system and method. Background technique [0002] Traffic congestion in modern cities is a common problem. With the advent of the automobile society, how to improve the traffic efficiency of the road network and reduce the average delay of vehicles and exhaust emissions is a problem that needs to be solved urgently. Because of the existence of level intersections in the urban road network, conflicting traffic flows are inevitable, so a traffic light signal system must be set up. However, traditional traffic lights only consider traffic safety. It is necessary to study the optimization of traffic lights at intersections on the basis of ensuring traffic safety. [0003] At present, some research institutes and enterprises at home and abroad have made contributions to the optimization of intersection signals, and some devel...
