The embodiment of the invention discloses an expressway traffic model construction method based on digital twinning. The expressway traffic model construction method comprises the steps of obtaining static environment information and dynamic vehicle information of an expressway; constructing a scene static twinborn model according to the static environment information, and constructing a vehicle dynamic twinborn model according to the dynamic vehicle information; performing joint simulation on the static twinborn model and the dynamic twinborn model, and establishing a highway digital twinborn model; in the simulation process, the traffic stability state and the congestion state of each road section are recognized in real time according to the dynamic vehicle information, and the recognition result is dynamically displayed in the digital twin model. According to the embodiment of the invention, the combination of the highway digital twin model and the traffic state is realized.
