Dynamic coordinated control method for bidirectional different requirements of trunk road

Abstract

The invention relates to the field of traffic control and particularly discloses a dynamic coordinated control method for the bidirectional different requirements of a trunk road. The method comprises the following steps of (1) calculating a key intersection largest in traffic flow according to the historical data of a detection coil; (2) determining a plurality of different coordination strategies according to the different traffic requirements in the up and down directions of the key intersection, and calculating a coordinated timing plan in different coordination strategies through constructing a model; (3) finally, according to the traffic flow monitored in real time, voting and determining an optimal coordination strategy. According to the invention, the method can meet different traffic requirements in the two ways of a trunk road. By adopting the method, the traffic efficiency of the trunk road can be effectively improved, and the traffic jam of the trunk road can be relieved. Therefore, the travel time of citizens can be saved. Meanwhile, the energy consumption of vehicles can be saved, and the pollution of the traffic environment can be reduced.

Description

technical field [0001] The invention relates to the field of traffic control, in particular to a dynamic coordination control method for two-way different demands on arterial roads. 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 large and medium-sized cities in my country, which has seriously affected the sustainable development of the city. [0003] "Green wave belt" is a visual expression of "multi-point signal light control technology" in traffic control, that is, to implement unified signal light control in a traffic area or a...

Problems solved by technology

[0004] At present, scholars at home and abroad have done a lot of theoretical and practical research on the coordinated control of arterial roads, but the hot spots and focuses of their research are mainly on the static coordinated control method and how to obtain the maximum green wave bandwidth. When the traffic flow on the arterial road changes, the time setting of the traffic lights at the intersection cannot meet the needs of vehicles, which will easily cau
