摘要
为研究环境熟悉度与恐慌传播对人员疏散的影响机制,建立考虑环境熟悉度的恐慌传播模型和人员疏散仿真模型。首先,在SIR传染病模型中引入环境熟悉度,并采用多方法系统仿真软件AnyLogic建立恐慌传播模型分析环境熟悉度对恐慌传播的影响;其次,运用疏散仿真软件Pathfinder建立人员疏散仿真模型研究环境熟悉度与恐慌传播对人员疏散的联合影响。研究结果表明:人群的环境熟悉度有助于抑制恐慌情绪在疏散人群中的传播,从而有利于缩短人员疏散时间,但在高人员密度条件下,环境熟悉度过高会导致人群在不常用出口处拥堵,反而不利于疏散;总体上看,考虑恐慌会延长低、中密度下的人员疏散时间,但会促进高密度下且环境熟悉度较低时的疏散。研究结果可为人员疏散规律研究提供理论支持,并对疏散策略制定具有指导意义。
In order to study the influence mechanism of environmental familiarity and panic propagation on the pedestrian evacuation,the panic propagation model and pedestrian evacuation simulation model considering the environmental familiarity were established.Firstly,the environmental familiarity was introduced into the SIR infectious disease model,and the multi-approach system simulation software AnyLogic was used to establish a panic propagation model to analyze the influence of environmental familiarity on panic propagation.Secondly,the evacuation simulation software Pathfinder was used to establish a pedestrian evacuation simulation model to study the joint influence of environmental familiarity and panic propagation on pedestrian evacuation.The results show that the environmental familiarity of the crowd is helpful to inhibit the propagation of panic emotion in the evacuated crowd,so as to reduce the evacuation time.However,under the condition of high population density,too high environmental familiarity will lead to the crowd congestion at the infrequently used exits,which is unfavorable to evacuation.Considering panic will prolong the evacuation time under low and medium density,but will promote the evacuation under high density and low environmental familiarity.The research results can provide theoretical support for the study of pedestrian evacuation rules and have guiding significance for the formulation of evacuation strategies.
