基于AnyLogic的地铁枢纽站疏散动态标识研究

Research on Evacuation Dynamic Sign of Metro Hub Station Based on AnyLogic

为了解决传统疏散标识在突发情况下感知能力弱、信息不能及时更新、无法实现动态化调整等因素导致逃生引导效率低的问题,提出了疏散标识的动态呈现形式和信息提示内容,重点研究标识位置设置对疏散决策的影响.以南京新街口地铁站为例,基于AnyLogic的社会力建模方法,对957份乘客问卷调查数据分析可知,78%的乘客在紧急疏散过程中对标识提示的信息是信任的.并根据分析结果调整仿真参数,使仿真结果更加符合实际.通过避让疏散瓶颈以此改变动态标识位置设置的实验,并对比分析改进前后的结果,得到改进后的疏散时间较原先缩短了32.7 s,表明动态标识能有效提升疏散效率.

In order to solve the problem of low efficiency in evacuation guidance caused by factors such as weak perception ability,inability to update information in a timely manner,and inability to achieve dynamic adjustment of traditional evacuation signs in emergency situations,a dynamic presentation form and information prompt content of evacuation signs are proposed,with a focus on studying the impact of indication position settings on evacuation decision-making.Taking Nanjing Xinjiekou subway station as an example,based on the AnyLogic social force modeling method,the analysis of 957 passenger survey data shows that 78%of passengers trust the information indicated by the signs during emergency evacuation.And adjust the simulation parameters based on the analysis results to make the simulation results more realistic.The experiment of changing the position setting of dynamic signage by avoiding evacuation bottlenecks and comparing and analyzing the results before and after the improvement showed that the improved evacuation time was shortened by 32.7 seconds compared to the original,indicating that dynamic signage can effectively improve evacuation efficiency.
