The invention provides an intersection real-time simulation method based on digital twinning. The intersection real-time simulation method comprises the following steps: creating a digital twinning model; building a mobile frame in an intersection range and building a corresponding independent acquisition unit; collecting the number, position and speed information data of vehicles, and transmitting the data to the digital twinborn model in real time; performing intersection traffic simulation and real-time prediction; dynamically optimizing the timing scheme of the signal lamp based on simulation and prediction results; and controlling the mobile frame to change the data acquisition position and repeating the step 4 and the step 5. According to the simulation method, the real-time data is displayed in the digital twin model, so that the real traffic condition can be better reflected, the accurate simulation and dynamic optimization effects of the intersection traffic are realized, the accuracy of the finally acquired vehicle driving information is improved, and the traffic safety is improved. And the effects of flexible movement and corresponding regulation and control according to the change of the number of lanes can be achieved by matching with the movable frame and the adjusting frame.
