Abstract
Abstract: Simulating the evacuation behavior of people under anxiety is of great significance for solving the kinematic problems such as escape. At present, most at home and abroad studies consider the anxiety factors as the only medium of population evacuation without considering how external key factors affect anxiety factors in such emergency environments. The improved social force model is proposed, combined with Agent-based stampede risk assessment, the influence of key environmental variables on the anxiety factor is quantified. The psychological force parameters are introduced, and the impact of the anxiety factor on the actual evacuation process is applied to the model through the physical vector. The model carries out the selection of individual motor vectors by enhancing the heterogeneity of individual psychological behavior. Compared with the real evacuation scenario, the experiment results show that the improved social force model can better describe the individual evacuation behavior and are more realistic and convincing.
