A new method for 3D-simulating traffic accident based on VISSIM

Abstract

A new method (VVSC method) for 3D-simulation of traffic accident was proposed, which was based on VISSIM platform frequently-used in traffic flow simulation. The general technical route was introduced followed by discussing modeling method for five key issues including: 3D element modeling, system framework construction, vehicle trajectory and process controlling, crash effect design and environment design. In the end, a successful case with complicated conditions was presented to show the application of the new method. The key point of VVSC method was making full use of both VISSIM and its secondary development interface COM. VVSC method is suitable for forensic institutions to simulate traffic accidents with accurate, fast, and cheap style.
