Research On Reasonable Running Distance Of High Speed Railway Trains

China has a vast territory and uneven regional economic,so the demand for passenger transportation is enormous.With the acceleration of the construction of high-speed railway,The passenger flow of high-speed railway is increasing,and passengers’ requirements for travel quality are constantly improving.It is of great significance to study the reasonable running distance of train under the background of high-speed railway networking in order to increase the attraction of passengers,improve the passenger volume sharing rate,improve the quality of transport service and promote the rational division of passenger transportation market among different transportation modes.This thesis systematically analyses the influencing factors of reasonable running distance of high-speed railway train from the perspectives of passenger travel choice and technical conditions of transportation organization.A method for calculating the reasonable running distance of high-speed railway train is proposed.The reasonable running distance of train includes the feasible running distance limited by the constraints of transport organization and the advantageous running distance affected by market competition.Select train speed,EMU overhaul,comprehensive maintenance time and train operation benefit to calculate the feasible running distance of high-speed railway trains;select speediness,economy,safety,comfort,punctuality and convenience indicators,determine the index weight by analytic hierarchy process,and use the non-aggregate model based on generalized cost to calculate passenger volume sharing rate of expressway,civil aviation,railway and high-speed railway under different train running distance,then the advantageous distance of high-speed railway can be calculated.The reasonable train running distance of high-speed railway can be obtained by synthesizing two kinds of distance.And analyze the difference of different types of passenger flow in travel choice.Based on the reasonable running distance of high-speed railway,the relationship between running distance and operation mode is analyzed,the advantages,disadvantages and applicability of different operation modes are summarized,and the transfer mode based on reasonable running distance is proposed.
