摘要:
为探究突发公共卫生事件下社交距离对地铁应急疏散的影响,以新型冠状病毒感染为例,研究新型冠状病毒感染等级、个体心理因素及心理安全距离之间的关系。针对不同新型冠状病毒感染等级下个体心理安全距离的改变,利用Pathfinder软件进行地铁疏散仿真模拟,从疏散人群密度、平均总疏散时间、平均拥挤时间、平均疏散距离和各出口利用率5个方面,探讨不同客流程度下社交距离对地铁疏散效果的影响。研究结果表明:当新型冠状病毒感染等级分别为低、中、高时,对应个体的心理安全距离范围分别为[0.08,0.2] m,(0.2,0.5] m和(0.5,1.0] m;仿真结果显示,社交距离为[0.08,0.2] m时综合疏散效果最差,社交距离为(0.2,0.5] m的综合疏散效果最好;不同客流程度下疏散情况变化趋势大致相同,人群密度的增加使得社交距离为(0.2,0.5] m时的疏散优势更加显著。
Abstract:
In order to explore the influence of social distance on subway emergency evacuation under the public health emergency,taking the COVID-19 pandemic as an example,the relationship among the epidemic levels,psychological factors and psychological safety distance of COVID-19 was studied.According to the change of psychological safety distance of passengers under different epidemic levels,the subway evacuation simulation was carried out by Pathfinder software,and the comprehensive influence of social distance on subway evacuation effect under different passenger flow degrees was discussed from five aspects,including evacuation crowd density,average total evacuation time,average crowding time,average evacuation distance,and utilization rate of each exit.The results show that when the epidemic levels are low,medium and high,the corresponding range of the passengers’ psychological safety distance are [0.08,0.2] m,(0.2,0.5] m and (0.5,1.0] m,respectively.The simulation results present that the comprehensive evacuation effect is the worst when the social distance is within [0.08,0.2] m,and the comprehensive evacuation effect is the best when the social distance is within (0.2,0.5] m.The change trend of evacuation situation is roughly the same under different passenger flow degrees,and the increase in crowd density makes the advantage of evacuation at the social distance of (0.2,0.5] m more obvious.
