Abstract:

Taking the transport system and the urban sustainable development as the targets of research, a novel analytic hierarchy process(AHP) algorithm to evaluate the adaptability of the transport system to the urban sustainable development was proposed. On the basis of analyzing the weak points of the traditional AHP method, sixty factors from the social, economical, ecological and transport domains were selected to form a evaluation index system. The singular value decomposition(SVD) method was used to improve the weighting factor calculation of the matrix with acceptable consistency. For the matrix with unacceptable consistency, the far and near degree was used to identify the coordinates of the significant elements and make its mean amendment of the direct mutual oppsition. A simulation work was performed for Shandong province, and the results indicated that the adaptability of the transport system to the urban development is decaying, providing a warning for the decisionmaking of the administrative officials.
