Research on Regional Road Safety Evaluation Based on Fuzzy Theory

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 regional road safety is constructed from three respects: importance, necessity and effectiveness. Based on numerous research works on road safety evaluation, the weights of evaluation indicators are determined by fuzzy AHP, and then a fuzzy comprehensive evaluation model for regional road safety is established. Finally, the examples of Beijing and Shanghai are given for illustration and main influencing factors restricting the traffic safety level of two cities´ are found.
