Safety Evaluation Methods of Road Traffic Based on Gray Cluster Theory

This article analyzes the characteristics and the applicability of the gray cluster theory, taking the traffic statistics of Jiangsu, Jilin, Beijing, Chongqing and Gansu as examples, and arriving at the conclusions that the road traffic safety levels of Beijing and Chongqing are relatively higher, the level of Jiangsu is ordinary, while the levels of Jilin and Gansu are relatively lower. This paper, aiming at road traffic safety assessment based on the gray cluster theory, explores the analysis thread and research steps, as well as analyzes the reasonableness of the results. What's more, the authors propose their own ideas on the selection of the evaluation indicators, the determination and processing of whitening values of different gray classes. In addition, this paper also carries on the forecast to this theory's application prospect and the trend of development.
