摘要
运用节点(N ode)和连接(L ink)构造公共场所空间网络模型对公共建筑物进行模拟。用不同颜色的节点表示公共场所中的房间和出口,用带箭头的连接表示公共场所中的路径和方向。结合已有的人群疏散速度公式,以疏散所用时间最短为目标选择合适的应急疏散路径。并以某二层商铺为例对该路径选择方法进行了验证和分析。结果证明,此方法可以较好地满足突发事件下,人群应急疏散预案设计的路径选择问题的需要。
A Link-Node space network structure model was founded for the simulation of the public place. Nodes with different colors represented the rooms and exits in the public place, and links with arrow stand for the routes and directions. Based on the formula of the evacuation velocity, and with the target of the shortest evacuating time, the appropriate evacuating path was chosen. The basic model of crowd evacuation plan was analyzed and validated with an example, and the result showed that the method of choosing the right route could satisfy the request of a crowd evacuation plan design.
