Comparison And Evaluation Of Design Scheme Of Interchange In Mountainous City

In this paper,based on the background of the policy of national urbanization,and through the research and evaluation of urban interchange construction program,to solve the traffic problems caused by the increase in traffic volume.According to the unique topography characteristic of mountain city,starting from the study of interchange design scheme selection point of view,through the summary of previous research results of interchange scheme evaluation,evaluation factors,establish the evaluation mechanism,establish a set of evaluation interchange new design model.Evaluation system mainly through the use of analytic hierarchy process will be a large evaluation of the problem decomposition,through the decomposition of the small problems to sum up the evaluation factors to build,and the use of matrix analysis method to calculate the relative weight of each factor.In the evaluation method,the membership function is used to unify the quantitative indexes,and the quantitative and qualitative indexes of fuzzy mathematics are used.At the same time,the paper combined with the specific case of the evaluation of the interchange design scheme,the rationality of the evaluation model is verified.The research of this thesis provides a strong theoretical basis for scientific decision of mountain city interchange project,the design scheme,save construction funds,improve transportation efficiency,reduce traffic accidents and other aspects of benefits,can be used as a powerful assistant in the future transportation infrastructure construction decision.
