Study On Method Of Rural Highway Network Pianning

With the building of the well-off society, the development of rural economy has entered in a new stage. As the essential facility in rural society, the program of rural highway plays an important role in improving the construction of rural highway and the development of regional economy.First, under the background of current rural economy, this paper aims to analyze the characteristics of rural highway, focusing on the distinctiveness in comparison to programming of other arterial highway. The research methods with more feasibility and operability are used in this paper, considering the existing circumstances in rural region of China.Then, the distribution of highway network has been designed in this paper. Through predicating the demands considering social economy and traffic in the planned areas, aiming at guaranteeing the network of rural highway being connected effectively, the reasonable scope of rural highway has been confirmed. Under the guidance of such thought from the node to the line, and then the whole network gradually, and according to the degree of importance, the layout of network with the method of optimal tree in Graph theory. This paper attempts at establishing a set of evaluation index system applicable to rural highway network, based on respectively processing these index both qualitative and quantitative, so as to be standardized. Furthermore, the weight involved in each index was calculated with AHP, and then with methods of value analysis and comprehensive fuzzy evaluation the program has been assessed.Finally, considering the development of rural highway in Yuanba district of Guangyuan city in Sichuan province, the theory analyzed previously was put into practice so as to be testified in the empirical study of programming the network of Yuanba's highway network.In a summary, on the one hand, theoretically, features of rural highway network has been analyzed through suitable methods and models; on the other hand, practically such theory was put into practice in the case study of the construction of Yuanba highway network.
