人行桥上突发事件下的人群恐慌行为模型研究

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

人行桥是人员密集场所,在突发事件下,容易导致人群拥挤踩踏。目前的人群仿真技术对恐慌情绪考虑不充分,不能全面描述人群行为。在综述人群行为仿真技术的基础上,提出了个体的结构和假设,给出了人群在恐慌情绪作用下个体的行为描述,构建一种恐慌情绪感染模型,在计算机上编制了演示系统,从而验证本文模型的合理性。

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.
