| Transportation plays a decisive role in urban development.With the rapid development of the national economy,traffic congestion is becoming more and more serious.Subway as a public transport has become the main goal of urban transport development in various countries.At the same time,the safety of the subway has aroused people’s great attention.According to statistics,there have been many serious subway accidents at home and abroad.Therefore,how to do an emergency evacuation of subway station personnel in emergencies has become a widespread concern of the society.At present,researches on this issue at home and abroad mainly focus on three aspects:mathematical modeling,observation and questionnaire survey,and computer simulation.However,because the mathematical model does not take into account the differences in the characteristics of the people,and the questionnaire survey can make up for this deficiency,but it cannot consider the impact of changes in the objective environment of the subway station on the evacuation effect.Computer simulation can establish a simulation model for specific scenarios,so I select the method of questionnaire and computer simulation.Firstly,the questionnaire survey is conducted to analyze the psychological and behavioral responses of different people under emergencies.Based on statistical analysis methods,the influencing factors and relevance of emergency evacuation behaviors and the specific behavior choices for different routes are summarized.It lays a reliable basis for the following simulation modeling Then,through Anylogic software,an emergency evacuation simulation model is built based on the pedestrian library to fully simulate the emergency evacuation process and analyze the evacuation capability.Through the continuous change of the environment structure of the station,different emergency evacuation effects are studied and analyzed,and an optimized and improved scheme is proposed.At the same time,considering the impact of panic on the effectiveness of emergency evacuation,a simulation model of emergency evacuation psychological characteristics is constructed based on system dynamics,and the factors that influence the psychological transformation process and the degree of importance are summed up.Finally,the above research results are used to provide effective suggestions for the planning and design of subway stations and emergency evacuation management. |
