Research On Adaptability Analysis And Optimization Of Urban Fast Channel Network Planning Layout

With China’s urbanization process forward, expanding the size of the city, increasing vehicle ownership, the demand of transportation is also growing, traffic quality of service requirements are also increasing. Fast Channel has large capacity and high-speed characteristics, which makes it the important status and role in the urban transport system. In recent years, the planning and construction of fast channel network is in full swing.In this paper, "Research on Adaptability Analysis and Optimization of Urban Fast Channel Network Planning Layout" has been chosen as the subject. Then analysis whether the fast channel network is adapt to urban social, economic and transportation development, designed to ensure that the fast channel network layout is more reasonable, more well-functioning network of fast channel action for urban transport services.First, combine the theory and practical experience of the fast channel planning and construction, to make a definition of fast channel, then analysis the characteristics of the morphology and function of fast channel and fast channel network layout; summarized and clarified the meaning and effect of fast channel network adaptability, and from the impact of economic factors, traffic and social environment to analysis aspects of the layout, establish the index system of adaptability analysis, and proposed an method of adaptability analysis based on the entropy method and the gray correlation method; and then analysis the fast channel layout optimization, proposes the corresponding optimization measures and established a network of fast channel layout optimization of multi-objective optimization model; Finally, takes Jianyang City as an example, combines theory and practice, analysis the adaptability of Jianyang fast channel networks, and makes an optimization of one of the best fast channel networks.
