Research On Comprehensive Evaluation Of Transfer System Of Urban Rail Transit

Urban rail transit is the backbone of urban public transport system.As the key points of the urban rail transit network,transfer system is a large system engineering,which influences the operation,economic efficiency and service of the whole rail network.With the development of rail transit network construction and the increase of passenger volume,the transfer problems are becoming more and more.Therefore,study on the urban rail transit transfer system is important to improve the service and ensure the normal operation.Firstly,this paper introduces the transfer manner,infrastructure,and passenger characteristics.According to the transfer system characterices,analyse the function of transfer system,passenger walk streamline and the influence factors.On the basis of that,the main problems of transfer system are summarized in terms of facility layout and passenger flow organization.Secondly,with the analysis of connotation,construction principle and the frame of evaluation indicator system,the alternative indicators are set up.The indicator set includes of 11 kinds of indicator,such as crowding degree,transfer distance and transfer time.According to the characteristic of indictor,the final evaluation indicator system is determined and quantified.Thirdly,in terms of relative metrics and application fields,analyse the comprehensive evaluation method and index weight evalution method.And determine the rail transit system evaluation method as grey relational degree and fuzzy mathematics,and the corresponding mathematic model is established.Moreover,by taking the North Street of Line 2 Xi’an Metro as an example for study,the scientificity,practicality and applicability of indicator system and evaluation method are verified.And the improvement suggestions for the evaluation results are put forward.Finally,summarize the main conclusion and innovation points of this paper,and prospecte the developing trend of urban rail transit system.
