Independent research and application of crowd evacuation simulation software system in China:taking Pedynamics as an example
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 sub-way 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 car-ried 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 sta-tistics modules allow the multi-angle viewing of simulation results and evacuation data,thus enhancing the efficiency of engi-neering applications.The research results can provide technical support for the risk assessment of crowd evacuation.
