Layout Optimization Of Passenger Station Within Terminal

Railway as the backbone of status in China's comprehensive transportation system is an important national infrastructure, and has a special and important position and role in the development of society and economy, it is also affect the national economy. With the rapid economic and social development and increasingly fierce competition in transport market, railway is facing tough market challenges now. In order to respond to market challenges, railway puts great effort to develop passenger dedicated lines(PDL) with the reform of "raising speed". while PDL is introduced into railway terminal and participate in the construction of urban integrated transport, passenger station within the terminal is bound to re-layout, the layout is reasonable or not is not only impact on the terminal of its own development, but also an impact on the development of the city. Therefore, the research on the layout of railway passenger station has an important significance after PDL introduced into railway terminal.In this paper, the macro-layout optimization of passenger station within terminal is seen as the goal. Using systematic analysis of ideas, drawing on relevant existing theories, taking a combination of qualitative and quantitative methods, we do a lot research on the key issues of theoretical models in-depth analysis, such as the layout plan research methods of passenger station within terminal, hub passenger demand, layout factors of passenger station, passenger terminal layout and location theory.First of all, this paper discusses the relationship between the terminal and railway terminal, analyzes the layout factors of passenger station within the terminal. Then on this basis, the definition and principle of passenger station layout optimization is determined. Within these, methods and steps of layout of passenger station within terminal are proposed, then research directions and ideas are determined in this paper.Secondly, a quantitative method of layout impact factors of passenger station within railway terminal is studied and proposed in order to prepare for the establishment of the layout optimization model of passenger station within terminal.Thirdly, the 0-1 mixed integer programming model is established, in which the object is to minimize the sum of passenger travel cost, the railway passenger station investment costs and operating expenses, then computer programming is proposed based on LINGO algorithm. Finally, the model is used to optimize Cheng-du terminal.Finally, the full text is summed up, and a set of relatively complete layout method and the theory of passenger station within railway terminal are proposed. It has good practical significance and reference for the integration development of passenger transport system within railway terminal. And future research work is looked ahead at the end of the paper.
