Construction of the evaluation system for regional road traffic safety and application based on a grey integrated evaluation model

Abstract

It is the basis for making analysis of the status quo and implementing effectively road traffic safety management to launch the evaluation for regional road traffic safety, while the construction of scientific and effective evaluation system is the prerequisite of carrying out the evaluation. In order to provide a method for the evaluation for regional road traffic safety, a grey integrated evaluation model is exploited to investigate the scientific and effective evaluation system for regional road traffic safety. In this paper, the grey incidence feature vector method and grey incidence analysis are, respectively utilized to construct an evaluation index system for regional road traffic safety, and determine the index weights and then grey clustering and grey incidence. The ideal point method is used to establish a novel evaluation model of regional road traffic safety. Finally, the regional road traffic safety for 31 provinces and cities in china are investigated to illustrate the feasibility and effectiveness of the proposed model, and provide the basis of making analysis of the present situation and the difference for the provinces and cities in China. Based on the analysis of the model and case, the results show that the proposed model does not only realize the categorizations of regional security, but also the comparison and ranking for the evaluated regions in the same category.
