Control method and device for traffic signal light, computer equipment and storage medium

Abstract

The invention provides a control method and device for a traffic signal light, computer equipment and a storage medium. The method comprises the following steps that: obtaining traffic environment training data, and on the basis of a Q-Learning algorithm, carrying out deep learning on the traffic environment training data to obtain a Q matrix of which the combined traffic state corresponds to a combined intersection behavior; if current time is first preset time, in each preset period, obtaining the traffic states of a plurality of preset road sections to obtain the current combined traffic state; and on the basis of the current combined traffic state and the Q matrix, controlling the passage switching time of the traffic signal lights of the plurality of preset road sections. A Q-Learningalgorithm model is trained to carry out data modeling to obtain the Q matrix of which the traffic state corresponds to the selection behavior of the passage switching time of the traffic signal light. In a time period of traffic jam, a reinforcement learning result. i.e., the Q matrix, is used for realizing the control of the traffic signal light, the passage switching time of the traffic signallight is changed to improve an integral traffic situation and alleviate a traffic jam state.

Description

technical field [0001] The present invention relates to the technical field of artificial intelligence, in particular to a traffic signal control method, device, computer equipment and storage medium. Background technique [0002] With the development of the economy and the development of the automobile industry, traffic problems are becoming more and more serious, which affects people's travel on the one hand, and has become an important factor restricting economic development on the other hand. To fundamentally solve the problem of traffic congestion, in addition to expanding urban roads, transforming urban layout, and enhancing people's traffic awareness, artificial intelligence has become one of the important means to solve the problem of traffic congestion. [0003] The existing method of improving traffic congestion through artificial intelligence is generally to intelligently control the passing time of each direction indicated by the traffic light according to the tr...

AI Technical Summary

Problems solved by technology

This method refers to the intelligent control of a single traffic light signal, and only intelligently improves the traffic congestion of the corresponding road through the intelligent control of the traffic light signal at each intersection. It may lead to a reduction in the traffic efficiency of another road, and ultimately lead to an insignificant improvement in the overall traffic efficiency of the city or a certain area
