Abstract
As construction of roundabouts on high-speed roads has commenced, truck overturning has become a concern. This research describes a rollover model more generalized than those previously used in this application, accounting for the complex paths and varying tilt of heavy vehicles such as semitrailers. The model is applied to examine how close heavy vehicles encroach on critical rollover conditions, including for understanding whether inward circulatory superelevation affords considerable advantages over the commonly used outward design.
