Research On The Planning Of Artery Highway At City Node

In recent years,China’s social economy has achieved leapfrog development,and the level of urbanization is rapidly improved,which marks the start into the new period.With the development of urbanization,the modern transportation system has formed,and has been developing continuously to satisfy the increasing demand of urbanization.As the basic network of integrated transport system,the development of the highway is particularly prominent,which has becoming the backbone of economic development and urbanization.All along,the development of the highway is the basis of urban development,its development direction,density and positioning determine the layout of the future city,and also have a greater impact on the city’s economic,social,environmental,population and other aspects.at the same time,the city also put forward new requirements on the development of highway,the scale of the highway,technical level,quality of service.to some extent,also led to the development of the highway.At the same time,the contradictions between the city and highway have become increasingly prominent.The continuous expansion of urban scale has also made the "phagocytosis"of artery highway become more and more obvious.The phenomenon of urbanization of artery highway is endless.The traffic inside and outside the city have mixed together not only affects the efficiency of transit traffic,but also interferes with the internal traffic of the city,The relationship between the city and artery highway began to become blurred.How to deal with the relationship between the city and artery highway in the process of rapid urbanization has increasingly become the focus of urban planners and builders’ research.This Thesis first discusses the relationship between city and artery highway in detail and deeply,then research the influence of city node on artery highway and the influence of artery highway on city node from all aspects,not only give a more scientific understanding of the artery highway and the dynamic relationship between city node.but also tell us how to make the trunk network reasonablely layout at the city note for the next step.Secondly,the research on the rational layout of artery highway and city node is carried out.The research mainly focuses on two aspects:the transit mode of artery highway and the connection between artery highway and urban road.In the study of transit mode,the principle of layout of artery highway,the common transit mode and the adaptability of various modes are analyzed emphatically,so that the transit mode suitable for artery highway at different nodes is summarized.In the study of the connecting arterys to city notes,This thesis introduces the principle of convergence,analyzes the linkages between artery highway and different types of city roads,and the problems that should be paid attention to when connecting with each other.Thus,we can get the ideas and solutions for the choice of the linkages between artery highway and city roads in different situations.Then from the planning coordination,economic adaptability,road network reliability,environmental sensitivity four aspects of the rationality of the convergence of artery highway layout to conduct a specific quantitative and qualitative evaluation.Finally,taking the layout of Nantong Trunk Line as an example,an example is given.
