The invention discloses a traffic control method and system based on updating interval windows, and relates to the technical field of traffic management, and the method comprises the steps: obtaining a road image set in a preset time period through an urban traffic system; performing vehicle density detection to obtain a road flow set; a K-means clustering algorithm is adopted, clustering analysis is conducted on the road flow set, a preset time period is divided into a plurality of time periods, and each time period maps one road flow; according to the multiple road flows, signal lamp control analysis is carried out, control parameters are obtained, and a parameter control window is obtained in combination with multiple time periods; acquiring a real-time road image of the target road section and carrying out special vehicle detection; according to the special vehicle detection result, the control parameters are corrected, and corrected control parameters are obtained; and controlling the signal lamp of the target road section according to the corrected control parameter and the parameter control window. Therefore, the technical effects of dynamically updating the control parameters and improving the traffic change response capability are achieved.
