The social force model is widely used in crowd simulation. For this model, there are shiver and penetration phenomena in crowd evacuation simulation. After analyzing the cause of this phenomenon, the multi-thread optimization method was used to improve the social force model. As pedestrians were slow-moving in multi-obstacle scenes, the auxiliary navigation points were adopted to optimize the evacuation path of pedestrians. A simulated crowd evacuation simulation software was developed using an optimized social force model. The software can define a variety of crowd simulation parameters to achieve crowd simulation. The simulation experiment was carried out on the seismic evacuation scenario, and the experimental data was compared and analyzed. It is verified that the simulation software can deduct the evacuation behavior of the crowd and provide reference data for the evacuation strategy of the crowd.
