Personnel Behavior Characteristics And Emergency Evacuation Simulation Of Subway Evacuation

At present,the building of urban mass transit system is developing rapidly in our country.But,the rapid development of new equipment and control technology give rise to frail safety management、making engineering hard and some other problems.At the same time,the subway security issues is particularly important,due to the depths of the subway underground and high carrying capacity,high personnel density and limited exports for evacuationAccording to the characteristic of subway station,behavioral principle and personnel evacuation behavior characteristics,this paper collected a large number of basic characteristics and personnel behavioral response data by questionnaire survey and literature search and studied the influence of the special structure of the subway station and personnel characteristics on evacuation time.By research,most investigators are familiar with exit and the evacuation marks.Only a small number of groups can be skilled in using fire extinguishers and emergency button.Most investigators in an emergency situation can make correct reaction.A few investigators will make the wrong evacuation response and may hinder the evacuation process.In terms of correlation analysis,factors like gender,age,occupation,fire safety training experiences and riding frequency are associated with evacuation behavior characteristics.Aggregative relationship has little influence on evacuation behavior characteristics.The modeling of the article is based on Convention and exhibition center station of Zhengzhou Metro Line 1,studied the evacuation capacity in three situations including no train travel peak state,single train train travel peak state and double train travel peak state and the basic personnel characteristics’ influence on the evacuation process.In no train travel peak state and single train train travel peak state,the evacuation capacity is enough.The more people who has fire safety training experiences or high riding frequency there are,the shorter reaction time will be.This will speed up the evacuation process.In no train travel peak state,the mainly factors affecting evacuation efficiency are personnel speed and shoulder width.In single train travel peak state,the mainly factors affecting evacuation efficiency are the stairs width and gate location.Setting a 1 m vertical hinged gate near staircass in the model will improve theevacuation efficiency and reduce the evacuation time by 26.5s.At the same time,it also maintains the key link layout of the station.
