A Hybrid Model for Simulation of Crowd Evacuation

Crowd simulation has been widely used in virtual building evacuation, crowd behavior drilling, movie making, entertainment and many other fields. So far, it is still a difficult problem to synthesize realistic large-scale crowd rendering with an interactive frame-rate in the real-time applications. Therefore, efficiency is a pivotal problem to resolve. This paper proposes a hybrid approach to guide crowd movements by constructing a navigation field and local collision avoidance simultaneously. Crowd can take use of navigation field which records the optimal path and local collision test keeping them off obstacles with modified vector to reach their desired destinations. With our proposed method, we build a simulation environment for crowd evacuation and realized the evacuation in assembly occupancies successfully with excellent rendering result and high efficiency in reasonable frame.
