Evaluation of Road Traffic Vulnerability in Urban Agglomerations Based on Entropy Weight-TOPSIS Model

Abstract

Aiming at the problem of increasing road traffic vulnerability in urban agglomerations year by year, this paper proposes a practice-oriented model and method. Firstly, the index system of urban agglomeration road traffic is established on the basis of analyzing and sorting out relevant planning and design indexes at home and abroad. Secondly, based on principle, an evaluation model of urban agglomeration road traffic vulnerability based on entropy weight- model was constructed. Finally, an empirical study was conducted to calculate the indexes with software, and the corresponding indexes were put into the model for calculation. By comparing the calculated results with the grade classification standard, the vulnerability of the urban agglomeration and the corresponding urban road traffic was judged and the corresponding improvement Suggestions were put forward.
