Countermeasures of safety improvements for rural highways are of great significance to crash reduction and safety enhancement. In order to compare and prioritize the effects of different safety improvement measures with certain quantitative indexes in advance of actual implementation, a theoretically-synthetic evaluation model of effects of traffic safety improvement measures for rural highways was built based on the combination of analytic hierarchy process (AHP) and fuzzy logic theory. A MATLAB program was also developed for the model to improve assessment efficiency. The experts’ scoring method was employed to provide the initial judgment matrix of AHP and membership matrix for different safety enhancement projects, and quantitative results can be obtained with the application of the model. Through quantitative assessment with the model, side-by-side comparisons could be conducted according to the results, which can assist the decision-making process for traffic engineers. The theoretical model can play an auxiliary role in optimization of safety enhancement plans for rural highways.
