Abstract

A signal control method comprises following steps: through database, obtaining historical traffic state data of an intersection; through a training module, based on the historical traffic state data,carrying out intensive learning to obtain a signal lamp training model; and through a model library, storing the signal lamp training model, wherein the signal lamp training model comprises mapping relationship between the traffic state data and a control strategy, which indicates the light-on rule of the signal lamps of the intersection. The signal lamp training model is used to output the control strategy of the signal lamps of the intersection based on the real-time traffic state data.

Description

technical field [0001] The invention relates to the field of intelligent transportation, in particular to a signal lamp control method, related equipment and a system. Background technique [0002] With the continuous advancement of national urbanization and the continuous increase of urban population, urban traffic is becoming increasingly busy. And with the continuous improvement of people's living standards, cars have become an essential tool for people to travel, and the number of urban car ownership continues to increase rapidly, which brings more and more loads to urban road traffic, and urban traffic is becoming more and more The problems of traffic congestion and traffic accidents in large, medium and small cities are becoming more and more prominent. Although the development of information technology is advancing by leaps and bounds nowadays, the urban traffic control system still lags behind and cannot meet the increasing traffic demand. For example, in the most ...
