摘 要: 在引入元胞自动机概念的基础上,模拟分析了紧急情况下人员的疏散行为,并提出了一个新的疏散模型。该模型考虑了人员的个体差异和从众行为,并重点分析了各种情况下从众行为对疏散行为和疏散时间的影响。结果表明,从众行为与疏散场所中的人员密度、视野范围大小等都有很大关系,一般而言,从众行为将延缓人员疏散的时间。 In this paper,a two-dimensional cellular automat model is used to simulate and analyze the process of evacuation in the case of urgency.The new evacuation model considers occupant's individual character and following behavior.The emphasis is put on analyzing the influence of the following movement on the occupant behavior and evacuation time in several cases.The results indicate that the following movement will prolong evacuation time compared with minimum distance movement.And only in particular conditions that guides exist,the following behavior is beneficial to the evacuation process.The model developed in the study shows potential for evacuation strategy design in public places.
