Study On Comprehensive Evaluation And Optimization Of Transfer Efficiency Of Urban Rail Transit Transfer Station

In recent years,the rapid development of urbanization has promoted the construction of urban rail transit.By the end of January 2020,33 cities in China have constructed or officially operated urban rail transit.With the increasing length and number of rail line networks,the number of transfer stations has also increased rapidly.The quality of transfer efficiency is the most important factor for passengers.Low transfer efficiency is a problem that cannot be ignored during use.At present,the research on transfer efficiency of traditional rail transit is mainly concentrated in a single professional field(transport field / architecture field)-the transport field often focuses on quantitative efficiency calculation,while the construction field focuses on the impact of space environment on transfer efficiency,lacking quantitative and qualitative Comprehensive research.In this paper,the two are considered in combination,a comprehensive evaluation of transfer efficiency is proposed,and the internal relationship between the quantitative and qualitative factors of transfer efficiency is established.Taking Wuhan Zhongnan Road Metro Station as the research object,and using the Any Logic simulation platform,it comprehensively evaluates the transfer efficiency,points out the problems existing in the current transfer situation,and proposes an optimization plan.With a view to providing theoretical reference and data support for the study of transfer efficiency and the engineering practice of Zhongnan Road Station.This article first analyzes the organization of the transfer station and the passengers inside the station,and elaborates the six organizational forms of the transfer station and the passenger’s transfer flow and behavior characteristics.Based on the above analysis,comprehensively considering the characteristics of mathematical models(social force model and cellular automata model)and the technical performance of three commonly used microscopic pedestrian simulation software,it is considered that Any Logic platform can fully consider pedestrians’ own factors and the interaction between crowds.It has an open architecture and supports secondary development.Therefore,Any Logic software is selected as the technical support platform for this article.Then,construct a comprehensive evaluation index of rail transit transfer efficiency.Analyze the related literatures of the two majors of architectural design and transportation,and preliminary select the evaluation indicators,supplemented by the questionnaires for passengers and experts,and determine the comprehensive evaluation indicators of the transfer efficiency.The yaaph software is used to calculate the weights of the indicators and perform consistency checks at the same time.Dimensionless processing is performed on indicators with different dimensions to construct the index scoring standards.The Wuhan Zhongnan Road Interchange Station was selected as an evaluation case,and the site investigation was conducted on Zhongnan Road Station,including the issuance of questionnaires and the collection of field measured data.Calculate the questionnaire data to obtain the scores of the qualitative indicators;at the same time,perform modeling and simulation on the Any Logic platform.The simulation results are calculated with the actual measured data on the site to obtain the scores of the quantitative indicators.Finally,the scores of qualitative and quantitative indicators were comprehensively obtained,and the comprehensive evaluation score of Zhongnan Road Station was 74.88 points,which indicates that there were problems-long time intervals for train arrivals,high transfer density,slow passenger flow,and the space environment within the station.Safety with facilities does not meet passenger needs.Finally,based on the comprehensive evaluation index of transfer efficiency,design guidelines for improving the overall efficiency of rail transit in transfer stations are proposed.Based on the design guidelines and the evaluation results of the current situation of Zhongnan Road,the Zhongnan Road interchange station was optimized for the facilities and environment inside the station,and two optimization design schemes were proposed—optimization scheme 1 based on the status quo and adding facilities and streamlining Adjustment,optimization plan 2 will adjust the facility location and direction to optimize the flow line inside the station as a whole.Modeling and simulation were performed on the Any Logic platform,and the transfer efficiency of the two optimization schemes was evaluated.The scheme 1 scored 83.15 and the scheme 2 scored 85.59.Compared with the current evaluation result of 74.88 points,the two optimization schemes have improved compared to the current situation,and the optimization scheme 2 has better transfer efficiency.
