Emergency Evacuation Behavior Characteristics Research In Urban Operation Subway Station

Subway traffic has become the trend of urban transportation development.subway station is an important component of subway operation system,the problem of emergency safe evacuation arouse the attention of the society.Personnel evacuation behavior is the biggest uncertainty factors in the process of subway station emergency evacuation,as a result,urban operation station emergency evacuation behavior research has the vital significance.Supported by personnel evacuation theory and behavioral science theories,from the behavior's two key factors,environment and psychology,the environment characteristics of urban operation station and emergency psychological behavior characteristics were analyzed.On the basis of a large number of relevant research,some questionnaires on subway station emergency evacuation behavior were made,including basic characteristics,the acquisition and confirmation of information,the first reaction,affecting factors of evacuation route choice.SPSS software was used to analyze the results,it show that the highest credibility way to inform emergency information is station broadcasting system,the majority of people willing to put their mastery of the information sharing with others,the public security alert remains to be improved.The first psychological reaction is significantly associated with the first behavioral response.Familiarity,personnel density,light conditions and the language evacuation guidance a great influence on evacuation route choice,the influence degree of safety evacuation instructions signs,responses to congestion and obstacles,path complex degree and the distance from exports is related to personnel education gender,sex,age and relevant experience.Based on evacuation route choice factors questionnaire survey,a similar experiment was researched which about the behavior characteristics of emergency evacuation route choice in subway station,through observing,recording and visiting to verify the questionnaire survey.It found that,in the path of the familiar or have a voice evacuation instruction,people's evacuation speed is relatively fast and poor light conditions will slow down people's evacuation speed.People will ignore the complexity of the path and distance in the process of emergency evacuation.In case of congestion and obstacles,people will prefer first appeared in the line of sight path,rather than make a decision looking after.Herd behavior in each other familiar clique is more obvious.Finally,the Steering mode of Pathfinder software was selected to build the station model with reference to the plan of the Fuzhou South Station,and established 11 different evacuation scenarios by changing the parameters such as exit selection,evacuation speed and initial delay time.The characteristics of emergency evacuation behavior in subway station under the influence of environment and psychological behavior was represented in the simulation.The simulation process and results were in agreement with the similar experiment.The evacuation time and process of simulation were analyzed,suggestions were given.
