Through comprehensive analysis to the traffic safety of the expressway, this paper raises an evaluation system. On the basis of setting up grade evaluation, the paper adopts membership function and gets quantized evaluation index of the traffic safety of the expressway. Because performance of the common measure that can't be common between different indices, it utilizes fuzzy mathematics to make the indices standard; according to the law of deviation the paper determines the weight value of the evaluation index. The comprehensive appraisal model of the traffic safety of the expressway is set up by using the relevant principles of fuzzy mathematics. And it carries a comprehensive appraisal on the existing expressway safety for one province. The evaluation results indicate that the existing expressway traffic safety of this province belongs to `tree grades' which are identical with the real expert evaluation results, so this method is feasible.
