摘要:
为了解折返行为对异质人群的疏散影响,应用Pathfinder软件对地铁站异质人群突发状况下疏散折返行为进行研究。对人员面对不同情景时的折返意向进行调研,分析了疏散楼梯宽度、折返人员比例、折返位置、列车到站数量、折返人员类型等对地铁站疏散速率以及疏散时间的影响。研究结果表明:折返比例、折返距离和难度与稳定疏散期疏散速率呈负相关,与疏散时间呈正相关,疏散楼梯宽度倍数则反之;地铁站停靠的列车数量与疏散时间呈正相关;肩越窄、运动速度越快,稳定疏散期的疏散速率越大、整体疏散时间短。
Abstract:
In order to understand the influence of backtracking behavior on the evacuation of heterogeneous crowd, the evacuation and backtracking behavior of heterogeneous crowd in the subway station under the emergency situation were studied by using the Pathfinder software. The backtracking intention of personnel facing with different scenarios were surveyed, and the influence of the width of evacuation stairs, the proportion of backtracking personnel, the locations of backtracking, the number of arriving trains and the types of backtracking personnel on the evacuation rate and evacuation time in the subway station were analyzed. The results showed that the backtracking proportion, the backtracking distance and difficulty were negatively correlated with the evacuation rate during the stable evacuation period, and positively correlated with the evacuation time, while the multiple width of evacuation stairs was opposite. The number of trains stopping at the subway station was positively correlated with the evacuation time. The narrower the shoulder and the faster the movement speed, the greater the evacuation rate during the stable evacuation period, and the shorter the overall evacuation time.
