Based on the needs of building real traffic twin scenes, this paper proposes a traffic twin scene scheme architecture based on edge-cloud collaboration, and introduces the key technologies involved. This paper explores the data processing scheme of multi-node cooperation when the road traffic flow is large, and combines the detection and identification technology of traffic participants to complete the accurate mapping of traffic participants and twin models, and establish the driving and exit mechanism of the real traffic participant model to achieve High-fidelity digital traffic twin scenarios.
