Abstract

Based on traffic wave speed formula and May speed-density model of follow-up theory and its characteristics, catastrophe mechanism of traffic jam is revealed and the cusp catastrophe models on density is deduced and established from the catastrophe phenomena according to the collected data about speed and density, and the critical density of actual traffic jam and speed scope of threshold value is acquired. The establishment of the cusp catastrophe models on density and the determination of the critical density scope lay a theory foundation for the establishment of expressway traffic control and management strategies.
