This paper discusses an approach to incident detection on freeways that classifies traffic conditions at a single station rather than by comparing conditions at adjacent stations. The approach has been developed from a catastrophe-theory-based model of freeway traffic operations. Initial testing on two systems has provided encouraging results.
