Study On The Simulation Method Of Emergency Evacuation Plan In Station Area Based On The Multi-Agent

Modern large-scale passenger depot is a comprehensive transportation hub which consist in multi transport ways. It is the site where a large number of passengers gather and distribute. Once emergency happened, there will be significant casualties and property losses. How to implement the station evacuation plan under the background of the emergency events, it is a major issue which should to be solved for the current large passenger station of our country. The problem haven’t been well solved in both aspects of theory and practice. This paper is based on the key plan-scientific research project of ministry of railways which is called "further research of operation management and intelligent service for large passenger station ". Aiming at the complexity of traffic evacuation problems for large passenger station, and combined with the actual data of Beijing South Railway Station, this paper study the simulation method of emergency transportation evacuation for large passenger station based on multi-agent model.This paper first analyzed research status in and abroad. Then carried on the system analysis on the station emergency evacuation question, which mainly includes the analysis of the station emergency evacuation content, the impact analysis between emergency events and traffic and the analysis of emergency transportation evacuation strategy. Then analyzed the simulation method of station traffic emergency evacuation based on the theory of Multi-Agent system. The design method and simulation method of station emergency transportation evacuation multi-agent system was put forward on. The following contents are mainly included:build the traffic emergency evacuation multi-agent system for the station, including the evacuees subsystem, evacuation management subsystem and the evacuation space subsystem, two evacuation models were built respectively with multi-agent simulation software Netlogo which is the emergency transportation evacuation model and the station-shelter evacuation model. Finally, analyze the traffic emergency evacuation simulation examples of the Beijing south railway station. Based on the analysis of the simulation environment of road network for Beijing south railway station, the paper put forward different types of emergency transportation evacuation plans and the simulation was analyzed. It includes the traffic evacuation plan simulation analysis under the emergency events of physical destruction of station road, the traffic evacuation plan simulation analysis under the emergency events of station road functional damage, the traffic evacuation plan simulation analysis under the normal emergency events of physical destruction and functional damage for station road. And corresponding traffic management measures were put forward according to the analysis conclusion.
