A Fuzzy Assessment Model for Traffic Safety in City: A Case Study in China

摘要

According to the principle of theory combining with practice, preliminary indicators of road safety evaluation are selected by integrating the characteristics of road traffic safety in China. On the basis of preliminary indicators, evaluation index system of traffic safety is constructed from three respects: accident rate, accident severity and the improved level of safety management. Considering the fuzziness, dependence and interaction of assessing indices, we applied the fuzzy method to assess traffic safety, and the evaluation and grading criteria for different indexes were presented. Finally, the practical value of the evaluation system and the evaluation model proposed in this study were proved by case study. Furthermore, the results of the study may provide reference for the traffic management departments.
