abstract

In order to meet the demand of passengers for travelling and make their travelling more convenient, the railway operator must ascertain the operational train number, section, classes, stop stations and appropriate departure and arrival stations for passenger trains. The nodes of railway passenger transport are the generation and attraction points of passenger flow in the railway transport network. Starting from the analysis of the economic and social attributes as well as railway resource allocation of the Passenger Dedicated Railway Line (PDRL) covered nodes, this paper introduces the concept of the importance of nodes. On the basis of analytical hierarchy process (AHP), the paper studies the quantitative index of the nodes transport distribution capacity in the PDRL network and calculates the evaluation indexes of importance of those city nodes. Thus, in the light of the assessment results, the paper sets up the three-level hierarchy in the importance of city nodes covered by the PDRL. Based on that, the paper proposes that the first-level nodes serve as the departure and arrival stations, the second-level nodes adopt the fluid and alternate stop stations, and the tertiary-level nodes take the form of “all-stop” for low-class trains so as to build a multi-objective programming model for the PDRL train line planning. With the lingo 8.0 program, the train line planning optimizes the calculation of stop stations. This method has been applied in the PDRL train line planning of Wuhan-GuangZhou High-Speed Railway Line and proved to be effective in reducing the complexity of the train line planning problem according to different modes of passenger flow.
