Multiple strategies based traffic control method and system

Abstract

The invention provides a multiple strategies based traffic control method and system. The method comprises the following steps that S1) city roads are divided into traffic control subareas, and corresponding control strategies are executed according to different saturation degrees of the road network of the traffic control subareas; S2) the control strategy is adjusted according to the average vehicle occupancy of different roads and the average saturation degree of a corresponding crossing in the road network of the traffic control subarea; and S3) green light time of key roads in the trafficcontrol subareas with inconsistent states is adjusted, so that the traffic state of each traffic control subarea is consistent. The different traffic control subareas are divided, the traffic conditions of the road network, roads and crossings of the subareas are taken into integrated consideration, different controls strategies are selected for different traffic states, the traffic condition inthe traffic control subarea is evaluated, and the green light time of key roads is adjusted.

Description

technical field [0001] The present invention relates to the technical field of traffic control, and more specifically, to a multi-strategy-based traffic control method and system. Background technique [0002] With the rapid development of my country's urban traffic construction, the number of motor vehicles in many cities has increased sharply. At the same time, traffic pressure is increasing. According to statistics from the Traffic Management Bureau of the Ministry of Public Security, as of the end of 2014, the number of motor vehicles in the country reached 264 million, including 154 million cars. There are 35 cities in the country with more than one million cars. Beijing, Chengdu, Shenzhen, The number of cars in 10 cities including Shanghai and Guangzhou exceeded 2 million. The "common problem" of traffic congestion will appear in more and more cities. Therefore, the two major problems urgently needed to be solved in our country today are dealing with traffic congesti...

Problems solved by technology

[0010] In the traffic road network, the traffic flow is basically conserved, that is, the traffic flow entering the road network and the traffic flow flowing out of the road network are basically balanced. The current traffic control does not fully consider the traffic conditions of the road network
