行人疏散问题已引起学者们的广泛关注。通过对行人疏散动态行为特性进行研究，制定相关应急疏散策略对人群进行有效地控制和疏导，是减少拥挤踩踏事故发生的主要手段。本文从微观角度，运用启发式力学模型描述行人的运动行为，并且考虑视野条件、建筑物规模及信息获取等因素对疏散行为的路径搜索和选择过程的影响，建立考虑从众效应和信息传递过程的行人疏散仿真模型。仿真结果表明，从众行为能够从一定程度上提高行人的疏散效率，在密集的人群中，盲目从众会导致局部拥堵现象发生。

Pedestrian evacuation has become a focus problem,and it has been widely concerned by scholars in recent years. It is very useful for managers to study the dynamic movement behavior of pedestrian evacuations. Making scientific evacuation strategies and effective controlling policies are the keys to reduce the accidents and guarantee the safety of pedestrians. In the microscopic level,based on the heuristic force-based model,an integrated simulation model is proposed to describe the herding behavior and information spreading process in pedestrian evacuation. The impacts of the factors on pedestrian route choice behavior,which includes the vision field,structure size,and gained information,have been included in the model. The simulation results show the herding behavior can improve the evacuation efficient in some level. In a density crowd,the herding behavior may lead to local congestion.
