Abstract

The invention provides a traffic signal lamp regulation and control method and device and a computer readable storage medium. The method comprises the steps of acquiring training samples according tohistorical control data, wherein each training sample comprises historical signal lamp timing, historical traffic measurement and historical traffic indexes; training according to the training samplesto obtain a mapping function; acquiring actual traffic measurement and actual traffic indexes; and according to the mapping function, the actual traffic measurement and the actual traffic indexes, calculating to obtain the timing of the signal lamp to be output. According to the invention, the problems of poor performance of a signal lamp control system and poor final performance of the signal lamp control system caused by errors of the traffic model in the initial interactive training process of the existing signal lamp timing scheme can be effectively avoided. The initial performance and the final performance of the signal lamp control system are improved.

Description

technical field [0001] The present invention relates to the technical field of traffic control, and more specifically, to a traffic signal control method, device and computer-readable storage medium. Background technique [0002] With the acceleration of urbanization and the popularization of motor vehicles, people are facing the problem of increasing traffic congestion. Without adding new traffic roads, it is an effective way to solve the problem of traffic congestion through reasonable traffic control, improving road utilization efficiency, and then improving traffic efficiency. [0003] At present, the traffic model-based signal light control scheme has been applied in the signal light control system. Traffic models usually include traffic flow models, queue length models, delay models, etc., which establish the mathematical relationship between traffic measurement, signal light timing, and traffic status or traffic indicators. The signal light control scheme based on t...
