Calculation Of Urban Rail Transit Station Carrying Capacity And Analysis Of Passenger Flow Control

Under the background of persistent extension of the urban rail transit network,further,its passenger volume will increase,and the urban rail transit station will serve as an important passenger flow distribution center for the urban rail transit system,and passenger demand will continue to increase.How to delineate the gathering and distributing course of pedestrians in station,analyze the station carrying capacity under reasonable service level,and find out a reasonable and effective station passenger flow control method based on bearing capacity is an important basis for station design,operation and management.The urban rail transit station is taken as the research target in this paper,starting from the traffic characteristics of the passengers in the station,based on the two bearing capacities,this paper proposes the basic carrying capacity and carrying capacity of urban rail transit,and puts forward the passenger flow control method of the urban rail transit station.The analysis provides a basis for the operation and management of urban rail transit stations.First of all,based on the study of mechanics,environmental science,and study of relatedfields scholars,combined with the operation process of the station system,the concept of satisfying certain safety conditions based on the random selection of the passengers' basic carrying capacity and inbound carrying capacity is proposed.The capacity to expound the analysis,study the factors that affect the carrying capacity of passenger flow,establish two models of carrying capacity and carry out model solution analysis.The paper also carried out on-the-spot observations and video recordings of urban rail transit stations.The paper establishes the passenger behavior model for the main behaviors of passengers at urban rail transit stations,including passenger movement behavior models based on social forces,passengers' staircases,escalators-selection behavior models,models of passenger service desk selection,and boarding and leaving process of passengers.The willingness model provides the basis for the calculation of the carrying capacity of rail transit stations.Secondly,the paper analyzes the concept and method of stress testing and proposes a calculation method for the station's carrying capacity based on the “pressure” test.This method sets the station's basic physical model through the computer,combines the passenger traffic characteristics and the passenger behavior selection model.The passenger flow is increased in the model to obtain the limit value of the station under the limited conditions to calculate the station carrying capacity,the basic carrying capacity of XiaoZhai station is 6042 p,and the carrying capacity of that station is 37000p/h.Then,based on the basic carrying capacity of the station and the carrying capacity of the station,the thesis proposes a passenger flow control method based on the station carrying capacity.Finally,based on the survey data,this paper analyzes the fundamental characteristics of the passenger flow in XiaoZhai station,including the fundamental attributes of passengers,passenger traffic characteristics and passenger behavior selection characteristics.On the basis of the analysis of the survey results and the mentioned theoretical research,the Anylogic simulation software is used to analyze the case of Xi'an subway Xiaozhai station.The actual results prove the feasibility of the model.Based on this,a certain passenger flow control method and the congestion point evacuation measure for the station are put forward.
