The invention provides a vehicle variable speed limit control optimization method and system, a medium and equipment, and relates to the technical field of vehicle control, and the method comprises the steps: determining a path to be subjected to variable speed limit control, selecting a target road section, and obtaining the traffic flow data of the target road section; a real road network model of the target road section is constructed, and real electromechanical equipment position information of the road is carried into the road network model; the road network model is calibrated according to the traffic flow data of the target road section, and the road network model is used for simulating the situation that the number of main road lanes is reduced due to accidents of each sub-road section under different service levels; and constructing a variable speed-limiting dual-target optimization model, transmitting the traffic flow data simulated under each condition to the variable speed-limiting dual-target optimization model, and solving a corresponding variable speed-limiting control strategy by using an NSGA-II algorithm. And the safety and efficiency of the road section are optimized and improved through variable speed limit control.
