| Abstract | This research was conducted to investigate the operational effects of cross-slope breaks on highway curves. These breaks are created by the superelevation of the traveled way and the adverse shoulder slope. HVOSM simulation studies were performed on a variety of break designs to test the effects of curvature, speed and vehicle path on vehicle operations. The study findings revealed the importance of shoulder slope and width in designing the shoulder to accommodate vehicular recoveries on the outside of curves. Recommendations regarding design of cross-slope breaks, including treatments for special situations such as narrow shoulders, high superelevation and rehabilitation projects were derived from the research findings.
