Research On The Evaluation Of Connecting Performance Of Urban Rail Transit Transfer Station

The development of urban rail transit is of great significance for optimizing the urban spatial structure and perfecting the integrated transportation system.As the core node of rail transit,urban rail transit transfer stations have gradually become cities in addition to the basic functions such as the intersection of rail transit lines and passenger transfers.Transportation and economic center.Therefore,rail transit interchange stations should have an efficient and convenient connection system to achieve the rapid collection and distribution of high-density people.But for a long time,my country’s rail transit transfer station connection system has problems such as insufficient capacity of the connection system during peak hours and insufficient capacity of multiple transportation modes,and it has not fully played the core role of rail transit transfer station area transportation.In response to the above problems,the thesis focuses on the evaluation of the connection performance of rail transit transfer stations,takes TOD theory,efficiency evaluation theory,etc.as the theoretical basis,adopts the DEA method,and goes through the steps of index selection,model establishment,data collection,and model calculation.It is of great significance for the development and optimization of the rail transit interchange station connection system to obtain the performance evaluation results of the transfer station connection in Chengdu and propose corresponding optimization strategies.First of all,based on the actual development needs of my country’s rail transit,in view of the contradiction between the insufficient capacity of the transfer station connection system and the increasing connection demand,it is clear that the improvement of rail transit transfer station connection performance is a necessary condition for the development of rail transit and green transportation.Through combing domestic and foreign literature,summarize the shortcomings and shortcomings of rail transit transfer station connection system research,and clarify that rail transit transfer station connection performance evaluation has research value and practical significance.Secondly,analyze the status quo of rail transit interchange stations in Chengdu.Analyze the connection characteristics of rail transit interchange stations from the three aspects of peakhour flow,the composition and distribution of connecting facilities,and the proportion of connection methods;based on the location of the interchange station,land use structure,and daytime population density,it is clustered into four There are three types of stations,namely comprehensive hub stations,city-level central stations,general district stations,and urban peripheral stations;determine the space capacity collection range and methods of various connection methods,and collect relevant data.Then,study the relevant literature to select the five types of connection performance evaluation indicators for the transfer station,use the DEA method to establish a connection performance evaluation model for various connection methods,and combine the AHP method to establish a comprehensive evaluation model for the rail transit transfer station connection performance.Taking Chengdu rail transit transfer station as an example,the weights of five connection modes of four types of stations are determined by expert scoring method,and the AHP-DEA transfer station connection performance evaluation model is used for evaluation,and corresponding optimization strategies are proposed.Based on the above research and case analysis,it is found that the city-level central station has the highest comprehensive connection efficiency among the four station types,and each connection method and comprehensive connection performance are all effective;other station types have invalid connection methods,and the general area station The comprehensive performance of the comprehensive hub station is invalid.The connection system of various types of stations should be improved,and the shortcomings of different types of stations should be complemented,and the inefficient connection methods should be improved,so as to improve the comprehensive performance of the rail transit transfer station connection and speed up the transfer station Evacuate the crowd,promote the development of rail transit,and give full play to the function of the transfer station as the core node of urban transportation.
