Study of Panic Behavior Model for Crowd on Pedestrian Bridge in Emergent Event

Pedestrian bridge is a crowded place,and it easily leads to a crowd stampede in emergent situation.The current crowd simulation methods consider panic emotion insufficiently,and cannot comprehensively simulate crowd behavior.Based on the review on crowd simulation technology,a structure and the hypotheses for a pedestrian were proposed,a pedestrian's behavior description in a crowd under panic emotion was proposed,and a model of panic emotion contagion was set up.The demo system was realized on a computer.The simulation result verifies the rationality of the model.
