Dynamic coordination and control method of traffic signals of urban main road

Abstract

The invention discloses a dynamic coordination and control method of traffic signals of an urban main road. Aiming at characteristics of traffic low of the urban main road of our country, bidirectional vehicle flows of the main road continuously pass through by coordination of the traffic signals on the precondition of ensuring green light utilization time of each intersection and phase on the main road. According to a real-time traffic condition, public signal period time, a phase green signal ratio of each intersection and a phase difference between adjacent intersections can be dynamically calculated; and starting time of a coordination phase is optimized on line, and green conflicts of a bidirectional coordination phase of the main rod are avoided through early stopping and delayed emission of a left-turning signal in the coordination phase. According to the dynamic coordination and control method, average traveling time and an average stopping rate of the traffic flow of the main road can be effectively reduced, and an application effect is better than that of a tradition single-point timed control method and a static coordination control method, so as to provide an effective control method for dynamic coordination and control of the traffic signals of the urban main road.

Description

technical field [0001] The invention relates to a traffic signal control method, in particular to a dynamic coordination control method for traffic signals on main roads in cities. Background technique [0002] With the development of our country's social economy and the improvement of people's living standards, more and more cars have entered ordinary families, and problems such as traffic accidents, traffic congestion, environmental pollution and energy consumption have become increasingly serious. Travel time, travel safety, environmental quality and The quality of life is restricted by the traffic conditions, and the traffic problem has become a very serious problem in most cities in my country, which has seriously affected the sustainable development of cities and the construction of a harmonious society. [0003] Urban road traffic signal control is an extremely important aspect of modern urban traffic management. The quality of its management and control will directly ...

Problems solved by technology

However, these research results have strict physical requirements for traffic arteries, such as the distance between intersections must be equal or multiplied, otherwise the effect will be compromised, so it is difficult to popularize and apply in practice
