The invention relates to the technical field of traffic control, and provides a traffic flow control method and system based on a real-time video stream. The method comprises the following steps: collecting a video stream at a target traffic intersection; performing image processing on the real-time traffic video stream, and extracting associated features of traffic flow to obtain traffic flow related features; fitting a vehicle number change trend chart and a vehicle speed distribution point map; carrying out data visualization setting on the traffic flow data, and drawing a traffic flow thermodynamic diagram and a traffic flow time sequence diagram; a road traffic digital twin model is generated for traffic flow management and control simulation; obtaining a traffic flow prediction result through the road traffic digital twin model; and if the traffic flow prediction result meets the threshold limit of traffic flow optimization, optimizing the traffic flow. The technical problems of difficult traffic flow management and poor traffic order in the prior art are solved, and the technical effects of maintaining traffic safety and improving the traffic order are achieved.
