摘要
为探究低能见度下铁路枢纽候车区环境中,群组特性对人群疏散的影响,通过开展低能见度下个体和群组混合人群疏散实验,计算分析疏散时间、疏散速度、群组构型等数据,探讨不同人员密度场景下群组行为的动态特性。在此基础上构建疏散模型进一步分析群组比例的影响。结果表明:座位区走廊及出口前通道存在人群短时聚集的风险;中、低密度场景下,2人群组疏散速度显著大于3人群组,男性群组疏散速度显著大于女性群组;在疏散过程中,女性群组表现为慢速、有序,男性群组相对快速、无序。此外,仿真模拟结果显示,高密场景下,40%的群组比例取得的疏散时间最短。从实验分析及仿真结果出发,对考虑群组特性的低能见度下铁路枢纽候车区人群疏散提出建议,为管理者和决策者制定疏散策略提供参考。
In order to explore the impact of group characteristics on crowd evacuation in the waiting area environment of the railway terminal under low visibility,the dynamic characteristics of group behavior under different people density scenarios are discussed by conducting individual and group mixed crowd evacuation experiments under low visibility,calculating and analyzing evacuation time,evacuation speed,group configuration and other data.On this basis,an evacuation model is built to further analyze the impact of group proportion.The results show that there is a risk of short-term crowd aggregation in the corridor of the seating area and the corridor in front of the exit;in the medium and low density scenarios,the evacuation speed of the 2 group was significantly higher than that of the 3 group,and the evacuation speed of the male group was significantly higher than that of the female group;in the process of evacuation,the female group is slow and orderly,while the male group is relatively fast and disorderly.In addition,the simulation results show that in the high-density scenario,40%of the groups have the shortest evacuation time.Based on the experimental analysis and simulation results,suggestions are put forward for the evacuation of people in the waiting area of the railway terminal under low visibility considering the group characteristics,providing reference for managers and decision makers to formulate evacuation strategies.
