摘要
为明确主动避让行为对养老场所人员疏散的影响,建立考虑主动避让弱势群体行为的元胞自动机模型,模型分别考虑避让弱势群体前方行走区域、斜前方行走区域、前方和斜前方行走区域对人员疏散的影响;分析不同避让方式下弱势群体比例、行人密度、弱势群体位置分布对整体疏散结果的影响。结果表明:主动避让弱势群体行为能够降低疏散时间,增加疏散的通畅性;弱势群体比例的增加以及人员密度的增大会增加疏散时间,存在最佳的避让方式使得疏散效率最高。弱势群体分布在近出口区域能够显著提高疏散效率。
In order to study influence of active avoidance behavior on evacuation in elderly care places,a cellular automata model that considered behavior of active avoidance of vulnerable persons was established.The model discussed influence of avoiding front walking area,oblique front walking area,front and oblique front walking area of vulnerable persons on their evacuation.Then,impacts of these people's proportion,pedestrian density,and their location distribution on overall evacuation results under different avoidance methods were analyzed.The results show that actively avoiding vulnerable persons can reduce evacuation time and increase its smoothness.Growth in their proportion and that in pedestrian density will increase evacuation time,and there is an optimal avoidance method that can result in the best evacuation efficiency.And the efficiency can be significantly improved by distributing vulnerable persons near exits.
