Embodiment

[0086] Tianjin Dongli District is located in the main axis of the development of Jinbin, bordering the core area of ​​Binhai New Area in the east and the central urban area in the west. It is an important functional area of ​​the central urban area of ​​Tianjin and Binhai New Area. Tianjin's development model is the twin-city development of the main urban area and the Binhai New Area, and Dongli District between the two urban areas has become the main development area of ​​Tianjin. Jishan Expressway starts from Beijing-Tianjin Expressway and ends at Rongwu Expressway (Jinjin Expressway) in the national expressway network. It passes through Dongli, Jinnan, and Xiqing Districts along the way. According to the planning direction of Tianjin's urban development, the Dongli section of Jishan Expressway is very likely to enter the city within the design period. The method proposed in this patent will be used to judge and classify Jishan Expressway.

Abstract

The invention discloses a classification design method for expressways. The method comprises the following steps of: establishing an unequal-weighted gray BP neural network combined model; predictinga nonagricultural population quantity by utilizing the unequal-weighted gray BP neural network combined model; estimating and predicting an annual urban construction land new demand S1 (n=i); determining a practical maximum increasable urban construction land area S2; and dividing expressway types through carrying out comparative analysis on S1 (n=i) and S2. According to the method, expressway types are classified and refined, and new design concepts suitable for surrounding plot development are adopted for different types of expressways, so that expressway planning layout and surrounding areaurbanization process are developed harmoniously.

Description

technical field [0001] The invention relates to a method for classifying and designing expressways in the transportation industry, and more specifically, relates to a method for classifying and designing expressways. Background technique [0002] The traditional concept of expressway planning and layout believes that expressway is a closed and independent system whose main function is to ensure the transition of transit and entry-exit traffic. It does not classify and refine its type according to its location, ignoring the layout of expressways and the surrounding areas. relationship between urban development. However, as my country's urbanization process accelerates, more and more expressways split urban land, seriously hindering the expansion of urban construction land. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, provide a kind of expressway classification design method, classify and refine th...
