Research On The Method Of Highway Network Layout In High Urbanization Area

In high urbanization area, the boundary line of highway and city road approach fuzzy, urbanization brings notable increase of traffic demand. In this paper, the main aim of study is the highway network of high urbanization area, the method of layout is disscused. Based on the characteristics of high urbanization area, and combine the method of system layout in city road, a new method of highway network layout is put forward. The aim is adjust to the development of economy and society in high urbanization area, and promoting the harmonious development of urban and highway transportation.In this paper, first of all it starts with the characteristic of social economy in high urbanization area, the characteristic of highway network is analysed. Then, the ideas of highway network layout in high urbanization area are given by traffic location and urban space layout and industrial structure which infect the layout of high urbanization area.Then, the characteristic of current four-stage method and the limitation in application of high urbanization area are analysed, based on the characteristics of economy and highway transportation in high urbanization area, combine to the method of city spacial layout in system layout of traffic in city road, the impact of city special layout on highway network layout is qualitative analysed, an improvement of the node importance method and the modal of four-stage method are used, development prediction of highway transportation is quantitative analysed from highway transportation and society economy, an accurate result of traffic flow prediction is provided for highway network layout, finally, the highway network method which even more fit for the development of this area is given.At last in this paper, combine to the example of choosing highway network layout method in Nanhai District Foshan City, feasibility and validity of the method is analysed in practical application.
