A highway traffic safety evaluation based on the extension matter-element model

Abstract

In order to reflect highway traffic safety level, on the basis of research on assessment methods at home and abroad, the highway traffic safety evaluation method based on the extension matter-element model is established. Firstly, the affecting factors of traffic safety were analyzed and the evaluation index system of highway traffic safety was established. Then the weight of each index was gained by using the Analytic Hierarchy Process (AHP) and expert scoring method. Finally, the extension matter-element model of highway traffic safety was set up, the degree of traffic safety condition belonging to one grade was quantitatively given, and the weight of the evaluation index is made more accurate by using the extension set and dependent function. The example of application on the highway in Hebei Province shows that the method can effectively evaluate the highway traffic safety level, and comprehensively reflect the traffic safety level of the highway.
