摘　　要：为更加精准地分析与评估公共场所突发事件下人员疏散的需求,自主研发了新一代人群疏散模拟仿真软件Pedynamics。以某地铁场景为例,比较分析Pedynamics与商业软件Pathfinder和AnyLgoic用于模拟地铁车站不同客流量下的疏散过程,并进行讨论,提出改进人群疏散效率的措施。研究结果表明:Pedynamics软件采用前后端分离的架构进行模块化开发,易于升级维护;后端采用的人群疏散计算模型结合了人群疏散动力学特别是人员有限理性路径选择行为方面的研究成果,能够真实体现行人的疏散行为特征;软件前端的场景预处理界面能够帮助用户简单、快速地基于图纸构建疏散场景,可视化及数据统计模块支持多视角查看模拟结果和疏散数据,提高工程应用的效率。研究结果可为人群疏散风险评估提供技术支持。To more accurately analyze and assess the requirements of personnel evacuation during the emergencies in public places,a new generation crowd evacuation simulation software called Pedynamics was independently developed.Taking a subway scenario as an example,the comparative analysis of Pedynamics and commercial software Pathfinder and AnyLgoic for simulating the evacuation process of subway station under different passenger flow was conducted,and the discussion was carried out to put forward the measures for improving the crowd evacuation efficiency.The results show that Pedynamics adopts a architecture with the separation between the front-end and back-end for modular development,which makes it easy to upgrade and maintain.The crowd evacuation calculation model adopted in the back-end combines the research findings related to crowd evacuation dynamics,particularly focusing on boundedly rational path selection behavior of individuals,and it can truly reflects the pedestrians’evacuation behavioral characteristics.The scene preprocessing interface in the front-end of software can help the users to quickly construct the evacuation scenes based on blueprints.Additionally,the visualization and data statistics modules allow the multi-angle viewing of simulation results and evacuation data,thus enhancing the efficiency of engineering applications.The research results can provide technical support for the risk assessment of crowd evacuation.
