Study On Layout Planning Of Chengdu Railway Hub Passenger Station After Introducing Passenger Dedicated Line

Along with the passenger dedicated lines and intercity railways introducing into railway hub and participating in the urban traffic integrating construction, many railway hubs are facing the opportunity to re-planning, and the layout rationality places a significant impact on the urban development as well as the railway hub itself. So, under the new circumstances, the study of railway hub passenger stations layout planning is not only very important to integrate the resources of passenger transport system and to ease passenger capacity, but also to form a systematic rationalization layout to meet needs of passengers, and to fully reflect the people-oriented concept of railway construction.This paper takes the Railway hub passenger station layout plan as the main object of study and applies systematic integral thought, a combination of quantitative and qualitative method, station layout theory and comprehensive evaluation method to research passenger station layout and plan of the railway hub using Chengdu railway hub for the context. The thesis has divided the problem to three main aspects to present the systematic study: analyzing the profile of passenger transport system, building the theoretical model of layout and location selection, and evaluating the schemes of the passenger station layout.Firstly, based on the analysis of the relationship between passenger station and city development and the overall layout of railway hub, the author analyzes and summarizes the effects that introducing passenger dedicated line and intercity railway into the railway hub, as well as dividing the two modes of layout after the introduction. Based on these, the author clarifies the research direction after that the connotation of passenger station layout planning is defined, the objectives and principles are pointed out and several traditional methods are compared.Secondly, the paper summarizes the general situation and development planning of the hub city, and analyzes the current situation and problems of railway hub system. Then, the author proposes the rail passenger demand forecasting models and solutions from the existing railway line and passenger dedicated line. Thirdly, based on the analysis of the main influence factors of passenger station layout, the paper builds integer programming model with the object function of obtaining the minimum cost including passenger travel cost, railway investment cost and operating cost. Then the model is solved and adjusted actually in order to get the layout scheme selection sets for evaluating.Fourthly, the paper established a synthetic evaluation index system of the passenger stations layout schemes with quantifying the indexes. Subsequently, it adopts the comprehensive evaluation method of the hierarchical grey relation analysis to evaluate the layout schemes.Finally, the conclusion of the full paper is drawn which makes out that the research about the railway hub passenger station layout has practical significance and reference function, and the future research work is prospected.
