Research On Evacuation Simulation Ot Beijing Subway Traffic Facilities During Mass Passenger Flow

ABSTRACT:Subway is in an important position in urban rail transit,with the advantages of large capacity,high speed,punctuality,safety and energy saving.However,with the continuous improvement of the urban rail transit network in Beijing,the continuous increase of operating mileage and the continuous increase of passenger flow,the problems existing in the metro stations are also gradually exposed,These problems are related to the size of the metro station,the rationality of the facilities layout and the movement characteristics of the passengers themselves.In this paper,the paper studies the evacuation characteristics and evacuation of passengers at subway stations by using the method of "Literature Analysis and Research-Analysis of Passenger Evacuation Characteristics-Passenger Evacuation Modeling-Evacuation Simulation Analysis".In order to improve the transportation capacity of subway,Emergency evacuation plan and emergency command guidance.The research content of this paper mainly includes the following aspects:(1)To understand subway passenger flow,subway evacuation and the concept of access facilities,analyze the characteristics of passenger evacuation affecting subway passenger flow from the aspects of station environment,passengers’ own factors and subway personnel management,And determine the factors that affect passenger evacuation,as the main basis for setting simulation parameters.(2)Based on the field observation of Beijing Subway Station and the actual data obtained from the survey of Xizhimen Subway Station and Songjiazhuang Subway Station of Beijing Subway Station,the distribution characteristics of passenger flow,population velocity and density distribution are studied and analyzed,and the distribution rules of passenger flow in Beijing Subway Station are obtained.Passenger movement characteristics.(3)Taking the Song Jia Zhuang Railway Station of Beijing Metro as an example,based on the general procedure and parameter setting of AnyLogic software modeling based on social force model,a simulation model of subway station passenger evacuation is established.(4)Based on the data of AnyLogic simulation software and the data of Songjiazhuang station,the simulation and calculation of the evacuation of passenger flow at the peak of the staircase,escalator,gate and passageway are simulated and the evacuation results of the different facilities are obtained.According to the evacuation of passengers in the passage facilities,Put forward the optimization and improvement measures and other emergency management suggestions.
