Dynamic bidirectional green wave band intelligent coordination control method for urban traffic trunk line

Abstract

The invention discloses an intelligent coordination control method of a dynamic bi-directional green wave band for an urban traffic trunk road. The method comprises the steps of starting, processing coordination parameters, processing intersection parameters, processing time and processing cycle, etc. The method adopts a double-stage control structure, namely, a control layer of a traffic control center server and a control layer of an intersection intelligent signal controlling machine, through the information interaction and the coordination of the traffic control center server and the intersection intelligent signal controlling machine, phase sequence is optimized in an on-line manner; and common period, highway section upper phase difference, highway section down phase difference, the starting time of an upper coordination phase, the starting time of a down coordination phase, green ratio at each intersection and other key control parameters are optimized and calculated on a real-time basis. The intelligent coordination control method gets rid of the limit of equal intersection intervals required for the coordination control of the green wave band for the urban traffic trunk road, and realizes the unceasing travel of bi-directional traffic flows on the main road by applying the traffic engineering technique, the artificial intelligence technique and the automatic control technique, thereby reducing the parking rate while the traffic capacity of the trunk road is improved, and obviously reducing the traveling time.

Description

technical field [0001] The invention relates to a traffic control method, in particular to an intelligent coordinated control method for a dynamic two-way green wave belt of an urban traffic arterial line. 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 traffic conditions. Traffic problems have become a very serious problem in large and medium-sized cities in my country, and have 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 man...

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
