Quantitative Research On Supply And Demand Coordination Of Rail Transit Planning Network

With the rapid development of rail transit in China,some of the problems faced by China’s rail transit have gradually become prominent,one of which is the coordination problem between cities and rail transit.As the foundation of rail transit construction and operation,the coordination of rail transit planning network has not received enough attention.In the passenger flow forecast in the early stage of rail transit construction,when comparing the line network schemes,coordination was not included in the reference basis for comparison and selection.At present,the research on the coordination of urban transportation has gradually shifted from traditional qualitative analysis to quantitative research.However,there are relatively few studies and theories on the coordination of rail transit planning.Therefore,it is very necessary to study the coordination between the rail transit network and the city at the planning stage.The thesis mainly studies the coordination between supply and demand of rail transit planning network.From the specific process of urban residents’ rail transit,analyze and refine the factors related to the rail transit planning network,and then determine the specific connotation of the coordination between supply and demand of the rail transit planning network.Then,based on the fractal theory,combined with other quantitative methods,the specific connotation of the coordination between supply and demand of the rail transit planning network is specifically quantified,from the fractal consistency between rail transportation supply and urban transportation demand,the orientation consistency between rail transportation supply and urban transportation demand,and the linear coefficient of rail lines based on urban transportation demand,building a quantitative model of the coordination between supply and demand of rail transit planning networks from three perspectives.Finally,through the coordinated calculation and comparison of the two line network schemes in the Passenger Flow Forecast of the rail project in Hengyang,the quantitative model for the coordination between supply and demand of the rail transit planning network was tested and verified.In addition,some defects and deficiencies of this method are summarized and laid a foundation for subsequent research.
