【摘要】 以网格模型的基本思路为基础,应用元胞自动机模型的原理,通过简单的规则制定和参数给定,并充分考虑了人员的个体特性、从众行为以及人员疏散速度与密度之间的关系,建立了针对各种行为模式的大型公共场所人员疏散模拟模型．进一步通过引入引导人、诱导装置等,探讨如何在疏散过程中发挥引导作用,利用环境条件,促使从众行为朝着有助于提高疏散效率的方向转化．初步的模拟结果显示,已建立的模型较好地反映了人员疏散行为的细节,具有较强的合理性和一定的实用价值．更多还原

【Abstract】 A new occupant evacuation model had been proposed based on grid-base model and cellular automate model in this paper. Acconling to instituted simple rules and parameters, the new evacuation model considering occupant’ s characteristics and the following movement rule and the relationship between occupant’ s density and moving velocity, and then simulated the complex evacuation process in which an occupant can take different evacuation behavior. Furthermore, In order to make the following movement contribute to the improvement of evacuation efficiency, we analyzed the guidance effect in the evacuation process by setting guiders and inducement in pilot study. The result show that the model had reflected some detail of evacuation behavior. So the model is rationally and practically in a certain extent.更多还原
