Research on Comparison and Selection Method of Expressway Route Selection Based on Improved Osculating Value Method
To solve the problem of comprehensive comparison and selection of expressway route schemes reasonably and efficiently,the research on expressway route selection scheme based on improved osculating value method is carried out.On the basis of considering the influence of multidimensional factors,the optimal evaluation index system is established.The CRITIC method and the grey correlation method are used to calculate the index weight respectively,and the optimal combination weight is determined based on the chi-square distance combination weighting method.Finally,the route project information is coordinated and the improved osculating value method is used to realize the line scheme optimization.The results show that the K6 scheme is superior to the E5 and E1 schemes,and the judgment results based on this method are consistent with the actual demonstration of experts.This optimization method improves the scientificity and applicability of expressway route scheme optimization.The research results can provide some reference for the optimization of expressway route schemes.
