Traffic light control method and device

Abstract

The invention relates to a traffic light control method and device. The traffic light control method and device are used for controlling traffic lights at the intersection of a first lane and a second lane. The method comprises the following steps that: first vehicle flow on the first lane is put into statistics, wherein the first vehicle flow is the increment of vehicles entering the first lane in a current traffic light period; second vehicle flow on the second lane is put into statistics, wherein the second vehicle flow is the increment of vehicles entering the second lane in the current traffic light period; and passage time distribution of vehicles on the first lane and the second lane in a next traffic light period can be adjusted according to the comparison results of the first vehicle flow and the second vehicle flow, so that the lane of which the vehicle increment is large can have long passage time. With the traffic light control method and device provided by the above technical schemes of the invention adopted, traffic pressure at the intersection can be alleviated, and vehicle passage at different directions can be balanced.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to a traffic light control method and device. Background technique [0002] In the control of urban traffic, traffic lights are often used at intersections to guide the direction of vehicles at the intersection. All vehicles pass or pass at rest according to the instructions of the traffic lights, so that vehicles at the intersection can be ordered. Use public road resources. [0003] At present, the control of traffic lights is usually based on experience to set a fixed switching frequency, and within a cycle, set the specified vehicle straight time, vehicle left turn time and vehicle waiting time in this lane. However, the traffic pressure at intersections is high in actual road conditions, and the existing traffic light control cannot well balance the traffic of vehicles in different directions. Contents of the invention [0004] The technical problem to be...
