In China, many freeways were upgraded from ordinary roads, and these upgraded freeways have some unique safety characteristics. Limited by terrain, geology, hydrology and other conditions, it's difficult to improve the alignment for upgraded freeways and all the freeway design elements. First, the paper analyzes the relationship between alignment elements and safety, and chooses the key horizontal and vertical influencing elements. Then, the paper builds the upgraded freeway safety evaluation model with Analytic Hierarchy Process (AHP)-based Fuzzy Mathematics. Finally, the paper applies the evaluation model to Yan(Yan Tai)—Wei(Wei Hai) freeway to analyze its safety.
