Abstract:

The subway station is a typical place with dense crowd. When an emergency occurs, the chaos caused by crowd panic is likely to lead to stampede and other serious accidents. In this paper, a personalized P-SIR emotion contagion model is established to simulate crowd panic dynamics. Then situations of no intervention, administrator intervention and device intervention are set up for computational simulation experiments. Research results show that, in the absence of intervention, the distance from the exit to the panic individual has a great influence on the number of panic infected individuals. When the administrator intervenes in the panic crowd, its position has a great impact on the intervention effects. When the equipment is used for intervention, the intervention effect is related to the individual’s own personality. The research results can provide important theoretical support for crowd control in emergencies.

Key words: panic, P-SIR emotion contagion, intervention strategy
