基于Pathfinder的郊区集市人员疏散行为研究

A Study on Evacuation Behavior of Suburban Bazaar Based on Pathfinder

基于郊区集市现状,利用Pathfinder对北京某郊区集市的疏散情况进行模拟验析,通过设置出口选择和人员等待两种方案得出集市出口利用率、出口的流率和疏散的时间等相关数据。直观比较疏散的时间来分析不同方案的疏散效果,在指挥协调之下,疏散效率明显更高;安全出口的利用率越高,疏散越快。为集市疏散方案的制订提供理论依据。

Based on the present situation of suburban bazaar,the evacuation situation of a suburban bazaar in Beijing is simulated and analyzed by using Pathfinder.The relevant data such as exit utilization ratio,exit flow rate and evacuation time are obtained by setting up two schemes:exit selection and personnel waiting.The evacuation efficiency is obviously higher under the command and coordination,and the higher the utilization rate of safety exit,the faster the evacuation,it provides theoretical basis for the formulation of bazaar evacuation plan.
