Research On Matching Degree Of Passing Facilities Transit Capacity Of Urban Rail Transit Transfer Station Based On Pedestrian Flow Characteristics

The construction of rail transit in each city of our country has gone through the phase of building and accumulating planning and design experience.Therefore,some problems emerged during the construction process.The various facilities within the station are interrelated rather than independent.Passenger flow and facilities need to match each other.Whether the facilities in the subway transfer station are reasonable and whether the facilities capacity can meet the passenger flow Whether the demand and service level can meet the requirements is the key and difficult issues that need to be considered during the planning and design stage of the transfer station as well as the operation and management.Therefore,these factors should be fully taken into account in the interior design of rail transit station buildings.This article first systematically elaborates the traffic characteristics of pedestrians and pedestrians.The characteristics of passenger flow and passenger flow in urban rail transit stations are analyzed in detail,which lays a theoretical foundation for the follow-up research.Secondly,the paper introduces the transfer form and the advantages and disadvantages of different forms of urban rail transit transfer stations.It elaborates on the classification of facilities and equipment of transfer stations,and defines the access facilities studied in this paper as a channel,stairs,escalators and gates,based on the characteristics of pedestrian flow,combined with three parameters of traffic flow,considering various influencing factors,adding impact coefficients,improving the calculation formula of passing capacity,and proposing the ability to pass through the escalators and gates The calculation method provides the basis for the study of the ability matching degree.Thirdly,through the analysis of the meanings of matching and matching degree,the matching capacity of passing facilities of urban rail transit stations is defined;the density ratio is used to measure the service level of station passing facilities,and the saturation and travel time are selected respectively from the aspects of capacity and efficiency.As a measure of the matching degree of the passing capacity of the station’s passing facilities,a corresponding matching degree assessment process was established.Finally,a case study was conducted on the matching ability of passing facilities through the Xi’an Metro North Street Station and the Seoul Subway’s Lishui Station.Through field investigation,the actual passing capacity of each transfer facility was calculated,and the services of each transfer facility were first evaluated.Levels,and then assess the ability of the passing facilities of the station through the matching of capacity and efficiency,the assessment results show that Xi’an Metro North Street Station does not meet the requirements,and Seoul Metro Lishui Station meets the requirements.In the Vissim 7.00 take different passenger flow values for simulation analysis,get the travel time,compared with the actual investigation,the simulation results are almost the same with the actual situation,compare and analyze the facilities matching capabilities of the transfer stations in different countries,and the instance site The bottleneck position is identified and optimization measures are proposed.
