Abstract: Based on Unity3D engine, this paper carried out the intersection scene simulation of modern tram, designed the scene model in the early stage, social vehicle driving module, pedestrian action module, traffic signal light changing module, rain and snow weather transformation module and so on. On the visual studio platform, C# script language was used to simulate the scene. The simulation results show that the tram, social vehicles and pedestrians can drive and walk correctly and orderly according to the signal lights, and can truly reflect the scene of the intersection. It provides a learning platform for tram drivers to be familiar with the scene of the intersection in advance, which has certain application value.
