The research was performed to study the operational characteristics of variable pavement cross slopes. Computer simulation of vehicles conducting passing maneuvers on high-speed two-lane highways was the methodology employed. The objective was to determine the effects of cross slope and centerline crossover break on lateral tire acceleration, vehicle roll angle and driver comfort. The research utilized two simulation models of vehicle dynamics--the Highway Vehicle Object Simulation Model (HVOSM), and the Highway Safety Research Institute/Motor Vehicle Manufacturers Association Phase 4 Model (HSRI/MVMA). Vehicle simulations were performed for a range of vehicle types, and various combinations of design speed and cross slope design. The research demonstrates the potential severity of the passing maneuver on highways with even minimum cross slopes. In general, the research stresses the need to provide a cross slope design that is the minimum consistent with drainage requirements.
