Weight Value Determination Method of Road Network Comprehensive Evaluation

Based on the analysis of different weight value determination methods,a new combination weighting approach is put forward.Firstly the compatibility of all different evaluation conclusions is discriminated by using hierarchical cluster analysis and Spearmen grade correlation coefficient.Therefore,a compatible methods set is gained.Then,the relationship of different conclusions in compatible methods set is tested with Spearmen grade correlation coefficient.According to the above results,the weighting coefficient of a formula,which is used to calculate combination weight,is determined.Finally,an example of road network comprehensive evaluation is introduced to show the feasibility of the method,which blends weight information of various methods and makes the conclusion more reasonable.
