Abstract: Compared with the traditional visual simulation of subway, there would be a lot of social vehicles and pedestrians in the visual simulation of modern trams. The simulation of their actions is a problem that must be solved in the visual simulation of modern tram. This article took an intersection of Songjiang tram T2 line in Shanghai as an example, simulated the scene of the modern tram in the intersection by using the Unity3D engine. The processing of intersection model, the simulation of social vehicle and pedestrian behavior at the intersection were mainly studied. It has a good reference value for the visual simulation system of the modern tram.
