Study Of System Optimization About High-speed Station Setting

With the construction of Chinese Passenger Dedicated Lines—PDL, more and more PDL are joined into the existing railway terminals. And in such circumstances, the problems of the railway high-speed passenger station building layout, scale determination, reasonable transfer with other traffic modes and so on change a lot, they are already not only the construction problems of the high-speed station, but also will become a series of optimal problems about the passenger transport system of railway terminals. Only do in-depth research on the system optimization of the related issues between railway terminals, urban relevant regions and the high-speed station layout, can we do a good job on the designing and planning of the high-speed station radically, and ensure the PDL joined into the existing railway terminals efficient, safe and unimpeded, people-oriented, it can also reduce and facilitate passengers' transfer, increase economic efficiency and social benefits, promote the combination of high-speed station construction and urban planning and development, and enable the construction of the high-speed station to possess the important significance of sustainable development.From the point of view of the passenger traffic system in the railway terminal which has the relationship with the high-speed station layout, this paper systematically investigates the theories and methods of the scheme for high-speed station layout after the PDL are joined into the railway terminals. And the research mainly includes the following aspects:(1) Starting from the source of high-speed station setting—the layout optimization of the passenger stations in the railway terminals, this paper re-plans and researches the railway terminal layout. However, this study is not completely negative, overturns the past and does it again, but on the basis of the existing layout of hinge, makes an in-depth analysis of the basic factors and dynamic factors which affect the layout of passenger station, then studies its location projects. According to the different conditions of PDL joined into the railway terminals, this paper establishes the high-speed passenger station layout models and solution methods, and ultimately determines the location of the high-speed station.(2) The transfer region of a city with the high-speed station as its center is designated for the study of passenger volume optimal distribution, and it is a comprehensive traffic hub, its main function is divided into regional passenger transport function and urban traffic function. Under the condition of knowing the railway passenger volume, the demand forecast can be divided into two parts, first the transfer volume between the railway passenger volume and other traffic modes, and the second is the traffic demand of the hinge service region. It is judged whether the total amount of the two above-mentioned forecast demands meets the transportation conditions. On the basis of meeting town roads planning and rail transportation capacity, recent and long-term assignment of the passenger station should be reasonably adjusted, and ultimately the scope of high-speed station is determined.(3) Based on the construction of the high-speed railway station, optimal methods of the passengers flow lines, transfer nodes, transportation routes and so on between railway and other traffic modes will be studied, in order to get optimal flow of integrated transfer.Finally, this paper summarizes the research work and research results of the full text, presents its innovation points, and then looks to the future work at last.The study of this paper is closely around the theme of high-speed station layout, and on the basis of collecting a large amount of the related papers' information, this paper uses and develops the passenger station layout theory, the passenger volume prediction theory, the comprehensive traffic integration theory and so on; qualitative and quantitative research on the system optimization problems of the passenger station are done by using the methods of the system optimization analysis, the network flow distribution model, the transport supply and demand equilibrium analysis, the ability harmony analysis, and the system evaluation, and then the model is solved by using computer programming, iterative method, and other mathematical methods. This paper also puts the new Chengdu station in the Chengdu hub and the Haikou station in the Haikou hub as the main line, puts the methods and examples throughout each optimization system of the passenger station, and finally calculates the optimal solution, thus proves that the theory of this paper tallies with the practice. Various results of this research provide guiding significance for the design and planning of high-speed station in the railway hubs of our country.
