Research On Layout Of Passenger Stations Of Highway Hub

In order to adapt to the development of highway transportation in our country, the main tendency of constructing stations yard system of highway transportation is to build public passenger and freight stations yard system energetically, which is highway main hub system. The Ministry of Communications has been proposed a "three main and one support"(the main framework of highway, the main channel of water transport, the main hub of harbor station, and the supporting system of modern traffic) long-term plan of construction of communications, then carrying out nationwide distribution plan of national arterial highway system and highway main hub system. Up till now, most of the departments of transportation at the provincial level have been planning the second level highway hub system under the general frame of highway hub system at the national level. Owing to the highway hub layout planning are being carried on in many cities at present, and the rolling revise of the layout plan is a continual process, the study on methods and applications of general layout planning of passenger stations of highway hub helps promote the work of layout planning programmed, standard and more scientific. It will provide scientific basis for passenger stations planning, make layout more scientific and rational and make the most of the highway hub. The study will help coordinate the hub and other transportation way to form comprehensive networks and promote the economic development of cities and regions. The research has important theoretical significance and practical value for improving the planning level of highway transportation basic facilities and advancing communications planning work modernize.In this thesis, the principle, method and steps of highway hub passenger stations layout planning are discussed. The decision of locations and capacities of the stations is analyzed. And the thesis makes a thorough analysis and study on approach of evaluation of layout plan. On the basis of describing the evaluation index with quantitative determination, the method of combining fuzzy comprehensive assessment with analytic hierarchy process to evaluate the layout plan and choose the most satisfying plan is applied. And a practical example is given. Furthermore, the thesis puts foreword that the influence on the traffic flowin the urban roadway network because of the different locating of the stations should be considered. And the evaluation of the average delay time of the roadway traffic network is proposed to help further compare the layout plan scheme. Meanwhile, how to compare the rationality of plans through operation simulation to guide planning is analyzed, and the simulation flow charts are given. In the end, this thesis points out that the decision work of layout planning of passenger stations of highway hub should accomplish the modernization of idea, organization, management and means. It is suggested that the modernized tool, GIS, can be applied to assist decision for the sake of improving the efficiency and quality of the planning.
