- Abstract:
-
Research on realtime traffic information classification is the basis of traffic guidance systems. In this paper, a high dimension feature vector based on a greyhistogram sampling of a road region image was proposed. The classification algorithms of linear discriminant analysis (LDA) and an improved KNearest Neighborhood (KNN) were adopted to reduce the high dimension vector and classify real time traffic information. The experimental results show that the proposed traffic information classification method can supply the same traffic information as what comes from the Beijing Traffic Management Bureau; the rate of identical information is as high as 91.7%.
