Study On The Transfer And Combination Between Regional Railay And Urban Rail Transit In Chengdu

Under the background of building interconnection and integration of the regional rail transit in Chengdu,this paper study the transfer and combination research between regional railway and urban rail transit(subway and the Regional Express Line)from both macro and micro levels.From the macro levels,this paper has studied on the integrated transfer and joint modes of regional rail transit,proposed the train of thought about transfer and joint research in Chengdu regional railway and urban rail transit.The factors affecting the selection of transfering nodes have been extracted and analyzed.After studied the grade classification of regional rail transit nodes under multi-point connection mode in study year(2020)with the application of Factor Analysis and Cluster Analysis.This paper has established transfer nodes location optimization model and worked out the location optimization program based on the lowest travel time of urban railway passengers in downtown.From the micro levels,this paper has analyzed the selection of transfering organization modes in important nodes,studied the flow design from the aspects of flow organization and optimization of equipment and facilities,and put forward some optimization suggestions finally.The main contents of this paper includes the following aspects:(1)After study of the regional rail transit transfer and combination development status at home and abroad,the train of thought about transfer and joint research in Chengdu regional railway and urban rail transit has been proposed.(2)Studying the connotation of regional rail transit integration operation and fulfilling approaches in Chengdu,this paper has summarized the integrated modes of transfer and combination between regional railway and urban rail transit in Chengdu.(3)The factors affecting the selection of transfering nodes have been extracted and analyzed.chapter3 has studied the grade classification of regional rail transit transfering nodes under multi-point connection mode in study year(2020)with the application of Factor Analysis and Cluster Analysis.(4)Transfer nodes location optimization model has been established based on the lowest travel time of urban railway.Passengers in downtown.Passenger transport limits,transfer times and variable values have been set as constraints.(5)On the premise of multi-point Transfer Mode,analysis of modes Selection of tranfer organization in important nodes has been finished.After study if the flow design from the aspects of flow organization and optimization of equipment and facilities,some optimization suggestions have been put forward finally.
