Research On Organization Of High Speed Line In Harmony With The Existed Line

With China's sustained and rapid economic and social development, Contradictions between the demand and supply of the railway passenger transportation become increasingly acute. To meet the higher requirements of economic development, it is inevitable to build high-speed railway which can make passengers and freights achieve "Smooth flow respectively ". However, according to the requirements of building resource-saving transport system and the need of sustainable development, it is necessary to make rational utilization of existing line's passenger facilities when to play the efficiency advantages of the high-speed line. Therefore, the theoretical research on transport organization and coordination of high-speed line and the existing line have important theoretical value and practical significance for the two lines' "harmonious development".Under the background of the Beijing-Shanghai high-speed railway, some useful work has been done in this paper which mainly include:(1) Analyze organization characteristics of the two linesBased on the domestic exsiting line and high-speed passenger special line of oversea, analyzing present passenger organization of the existing railway line and high-speed passenger line; making a transport comparison of the organizational characteristics of the two lines;(2) Form rational transit division plans of the two lines in initial stage and future stageUnder the principle of coordination, making a pattern selection of transport organization, and then supply a transport organization pattern for Beijing-Shanghai high-speed railway; Based on this pattern with the analysis of passenger flow, a rational transit division plan of the two lines in initial stage and future stage is finally formed;(3) Calculate the flow proportion of the two lines and compute the existing line's capacity utilizationUsing logit model to fix flow ratio; Analyzing the train structure and capacity utilization of the existing railway under the background of Shanghai-Nanjing line;(4)Calculate the two lines' capacity utilization after the phased transfer of the trains of existing lineAccording to the reasonable division plan, transfer trains of the line and overline respectively in the form of the phased stage;(5) Harmonize operation programme of the two linesOptimizing the operate programme with streaming effect of the existing line on the high-speed line, and an analysis of two lines' capacity utilization is made.
