An AHP Method for Road Traffic Safety

In order to grasp the factors affecting road traffic safety and discharge the potential hazard fundamentally, an AHP (Analytic Hierarchy Process) method, which suits for solving complex decision making was proposed in this paper. Started from the view of system science, this paper calculated the weights of the causes of road traffic accidents by establishing the AHP model of the major factors affecting road traffic safety. The results of the experiment showed that factors of drivers accounted for a large proportion of traffic accidents, in which speeding was the most active factor. The AHP method overcome the drawbacks of the traditional analytical measures which only considered one single factor, the number of traffic accidents, and obtained objectively the major causes of road traffic accidents with a comprehensive consideration of people, vehicles, roads and environmental influence. Finally, several corresponding preventive measures were proposed, which will play a guiding role on the development of road traffic safety.
