Analysis On Quality Evaluation Of Highway Network Based On Urban Agglomerations

With the rapid development of economic globalization, more and more countries have a profound understanding of the development of urban agglomeration within a certain area to promote economic and social potential of rapid development.Urban road network is a group of economic development and an important support for social interaction ,the development of its own speed and quality, determines the scale of urban agglomeration development and prospects in certain extent.Rapid development of high quality road network within the urban agglomeration, can further promote the links between cities and the socio-economic development. Therefore, the strengthening of urban road traffic network of urban agglomeration with a good theoretical and practical significance.In this paper,on basis of the elaborate features about road network in urban agglomeration ,urban road network quality evaluation as group study established the urban road network quality assessment group index system, from the perspective of macro and micro analysis of urban road network quality group of factors; the gray system theory in the evaluation of the gray clustering method, the quality of the urban road network evaluation group, and using AHP to determine weights of evaluation to ensure an objective evaluation of the accuracy; the last group of road network for Hunan City for example, the evaluation of road network quality empirical analysis, evaluation methods to verify the feasibility and effectiveness of the algorithm. Conclusion of the study show that the method not only has a better measure, while in practice also has a convenient operation, high reliability characteristics.The purpose of this paper is to provide theoretical guidance and reference about the quality of the urban road network evaluation group ,in order to promote the harmonious development of transport network and urban society and economy of urban agglomeration.
