On highway induction information validity evaluation based on AHP

This paper adopts the Analytic Hierarchy Process (AHP) to the establishment of a highway induction information validity evaluation system, and by pairwise comparisons between the factors that influence induction information this system provides judgment matrices on different levels. The corresponding normalization vector of judgment matrix´s biggest characteristic root be taken into fuzzy evaluation system as those influential factors weight vector. Then, this paper evaluates the static information, dynamic diffusion information, dynamic feedback information and overall induction information of a highway separately. The result indicates that this method have a good effect in evaluating the highway induction information validity.
