Shaanxi Province Road Network Planning Practice And Exploration

Based on the working experience of highway network planning in Shaanxi province, the main methodology and practice were studied in this dissertation. It is composed of seven chapters. In the first chapter, the purpose and function of highway network planning, as well as the research achievements in China and abroad were discussed. The backgrounds, contents and organization of this dissertation were introduced. Goals of highway network planning, in terms of the total length of the highway network as well as the share of expressway and over Class II highways in the network, were analyzed in chapter two by using of Network Connection Index and analogy methodology. The developing goals of Shaanxi arterial highway network were proposed. In the third chapter, the overall arrangements for highway network were studied through the Importance Index of nodes and links. A radiated national arterial highway network system and a secondary provincial highway network system were arranged. The traffic demand tends in the planning period were studied in the fourth chapter. On the basis of existed vehicular origin-destination (OD) surveying data, a combination model was introduced and calibrated to predict the traffic generation and distribution coordinately. The perspective traffic volumes at each special year for each road section were estimated with the help of transportation GIS software -- TransCAD. The sequcnce of highway network construction was studied in chapter five, by using of cost-effectiveness appraisal. The scopes of development for Shaanxi provincial arterial highway network within year 2001-2010 were proposed. A quantitative evaluation methodology for highway network impacts on socio-economic was put forward in chapter 6. The socio-economical impacts are mainly connected with three national production sectors, that is, construction, freight transportation and passenger transportation. Contributions of the planning highway network to Gross Domestic Products (GDP) were quantitatively measured by using of transportation volume prediction results and a GDP input-output matrix. Main conclusions of the dissertation were summarized in chapter seven.
