高校多功能体育馆周边路网应急疏散定量研究

Quantitative Study on Emergency Evacuation of the Road Network of Multi-Function Gymnasiums in Colleges and Universities

针对高校多功能体育馆周边路网形态对突发事件应急疏散时间的影响,通过构建方形网格式、环形放射式、混合式和自由式四种不同形态道路网络,并定义了道路拥挤度和车辆行驶速度两个参数,给出了车辆应急疏散的最短路径行驶方案,采用Dijkstra算法对车辆行驶路径优化进行程序设计。实验分析表明:2000辆车在混合式道路网络中应急疏散总时间最短,其次分别是环形放射式道路网络、方形网格式道路网络、自由式道路网络。这对于未来高校建设规划时,合理设计场馆周边路网形态具有一定的现实意义。

In view of the multifunctional gymnasium surrounding road network pattern influence on emergency evacuation time,by building a square grid,ring radial,hybrid and freestyle four different forms of road network,this paper defines the degree of road congestion and vehicle speed two parameters,then the vehicle emergency evacuation of the shortest path driving scheme is given. USES the Dijkstra algorithm is carried out on the vehicle path optimization program design. Experimental analysis shows that 2000 cars in the hybrid road network emergency evacuation shortest total time,second is respectively square grid ring radial road network,road network,freestyle road network. It is of practical significance to design the surrounding road network in the future.
