A receding horizon optimization method for traffic light and vehicle track control at a signalized intersection, relating to the field of intelligent connected vehicles, comprising the following optimization steps at each time interval: acquiring vehicle information in a target area (S1); solving a mixed-integer linear programming model by using the vehicle information in the target area to obtain traffic light states and vehicle arriving at intersection moments (S2); solving a vehicle queue lead vehicle track optimal control model by using the vehicle arriving at intersection moments to obtain vehicle queue lead vehicle tracks, and solving a vehicle queue following vehicle optimal control model by using the vehicle arriving at intersection moments to obtain vehicle queue following vehicle tracks (S3); and implementing vehicle track control by means of the vehicle queue lead vehicle tracks and the vehicle queue following vehicle tracks, and implementing traffic light control by means of the traffic light stat
