The invention discloses an intersection signal timing optimization method and system based on a GA-APSO algorithm, and relates to the technical field of traffic control. The method comprises the following steps: acquiring the traffic flow of an intersection; the traffic flow comprises the number of vehicles and the speed of the vehicles; inputting the traffic flow data into a multi-target timing optimization control model for signal timing, and obtaining a timing control result; the multi-target timing optimization control model is constructed based on a dynamic full value coefficient and a GA-APSO algorithm; the GA-APSO algorithm is obtained by embedding crossover and mutation operators of a genetic algorithm into an adaptive chaotic particle swarm; the multi-target timing optimization control model comprises a target function and a corresponding constraint condition. According to the method, the reasonability of intersection signal timing in dynamic traffic can be improved, and self-adaptive change is realized.
