Road profiles are analyzed with focus on road characteristics essential for heavy vehicle fatigue assessment. Road profile measurements indicate that roads contain short sections with above-average irregularity. Such rough sections are shown to cause most of the vehicle fatigue damage. An algorithm using a spatial-frequency description is developed to automatically identify rough sections. On the basis of the analysis, a new stochastic road model, with randomly placed and randomly shaped irregularities, is proposed.
