Traffic coordination control method of multiple intersections

Abstract

The invention relates to a traffic coordination control method of multiple intersections, belonging to the technical field of intelligent transportation. The method comprises the following steps: (1) establishing an intersection transportation control model containing mixed traffic flows; (2) solving the established intersection transportation control model containing the mixed traffic flows by using a chaos differential evolution algorithm. The method has the beneficial effects that the constraints of the mixed traffic flows are taken into account, and then, the traffic conditions of the intersections are more accurately reflected, so that a signal coordination scheme developed based on the traffic conditions is more reliable; minimum vehicle delay, minimum stop number and maximum pass capacity are targeted, so that the effectiveness of traffic coordination control is improved to the maximum. The traffic control method of the intersections containing the mixed traffic flows, based on the chaos differential evolution algorithm, disclosed by the invention, has the advantage that the problems of high dimensionality, nonlinearity and multiple constraints of the intersections can be excellently solved.

Description

technical field [0001] The invention belongs to the technical field of intelligent traffic, and particularly relates to a traffic coordination control method for multiple intersections. Background technique [0002] The load of urban traffic is mainly borne by the traffic trunk line, and the smoothness of the trunk line directly affects whether the traffic in the entire urban area can run smoothly and safely. As a key factor in the urban road network, it is of great significance to improve the overall urban traffic conditions to improve the coordination and control effect of urban arterial lines and reduce traffic delays and parking rates on arterial lines. In the past quite a period of time, the state has invested a lot of financial and material resources in the development of infrastructure. However, the available space resources in the city are becoming more and more scarce, and the construction cost is getting higher and higher. way is no longer feasible. Therefore, i...

Problems solved by technology

Therefore, when the control traffic light is the first phase, often the left-turning traffic flow of the intersection only needs one exit to accept the lane, while the entrance straight lane from the exit to the corresponding main road is waiting for a red light, which causes road resources waste, reducing the capacity of arterial roads, so there is a need to improve traffic control methods at intersections
