Dynamic Modeling of Crowd Risk Based on Improved Social Force Model
Crowd risk is a focus of public safety management.Theories of crowd risk and crowd dynamic models are reviewed to discover deficiencies of the existing models.Based on the social force model and the four-stage crowd risk theory proposed in this paper,a four-state crowd dynamic model is established.This model specifically simulates pedestrians dynamic characteristics in the formation process of crowd risk.It can be applied to study behavioral characteristics of the crowd,and be used for risk assessment and risk early-warning of crowded states.
