Traffic control method of intersections containing mixed traffic flows

Abstract

The invention relates to a traffic control method of intersections containing mixed traffic flows, 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, in particular to a traffic control method at an intersection with mixed traffic flow. Background technique [0002] At present, with the rapid development of my country's urbanization and motorization, the number of motor vehicles and road traffic has expanded rapidly. At the same time, the number of non-motor vehicles in households is still huge. Therefore, the problems of urban traffic congestion, traffic safety, energy consumption and environmental pollution have become the overall problems related to the sustainable development of the national economy. In the past quite a period of time, the country 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. Solving the problem of traffic congestion by build...

Problems solved by technology

Therefore, when the control signal light is in the first phase, the left-turning traffic flow of the intersection often only needs one exit to accept the lane, while the entrance straight lanes from the exit to the corresponding main road are all waiting for the red light, which has caused road resources. Wasteful, reducing the capacity of arterial roads, so there is a need for improved signal control methods at intersections
