Abstract

The invention provides a single-intersection signal lamp optimal timing implementation method based on an SUMO analysis model, a control device, electronic equipment and a storage medium. The method comprises the steps that a single-intersection SUMO analysis model is established; position and speed data of a vehicle on a lane are acquired, the position and speed data are substituted into a vehicle following model, and a simulated annealing algorithm is used for calculating to obtain a single-intersection optimal timing solution; traffic flow data between intersections are collected, the traffic flow data is substituted into the SUMO analysis model to carry out real-time signal periodic timing, and an optimal timing solution of a single intersection is dynamically modified and adjusted; afixed timing scheme is established and subjected to comparison; and quantitatively analyzing is carried out to obtain a global optimal timing solution. The key technology of the method is overall mathematical modeling of vehicle flow, and whether mathematical modeling is accurate or not directly influences the final effect; and a real-time analysis method is adopted in the modeling process, the speed and position conditions of each vehicle per second are calculated more accurately, and a global optimal timing solution in a signal period is calculated in real time.
