Abstract
It is significant to evaluate the importance of urban subway network nodes in the operation and management of urban traffic system. TOPSIS method is one of the multi-index comprehensive methods to evaluate the importance of nodes. But the existing TOPSIS methods have insufficiencies in estimating close degree when the importance of metro network nodes is evaluated and in the weighting algorithm when the features of network space are not concluded. In view of these issues, this paper puts forward corresponding improvement measures ∶ 1 ) with vertical distance and grey correlation degree to evaluate the close degree between the program and ideal solution; 2 ) design of local entropy weighting method suitable for the spatial network. At last, node importance of urban rail transit network of Beijing is evaluated with improved TOPSIS. The results show that the results obtained by improved TOPSIS method conform to the actual measurements and better than those with existing TOPSIS. The method is proved highly accurate and applicable.关键词
