Abstract

This application provides a method, device, and electronic device for controlling traffic lights. The method includes: acquiring trajectory data of vehicles passing through any target intersection in a traffic network and determining traffic characteristic parameters based on the trajectory data; determining the traffic state of each traffic flow direction at the target intersection based on the traffic characteristic parameters; determining the traffic problem type of the target intersection based on the traffic state of each traffic flow direction; and adjusting the original timing scheme of the target traffic light located at the target intersection based on the traffic characteristic parameters and the optimization objective corresponding to the traffic problem type of the target intersection, thereby obtaining an optimized timing scheme for the target traffic light. This can effectively address real-time fluctuations in traffic flow, alleviate traffic congestion, and improve traffic efficiency.
