Abstract

The highway-vehicle-obiect-s¡mulation model (HVOSM) was used to study ve- hicle responses and their sens¡tivity to var¡ous highway curve elements, After initial validation runs, a parameter study was conducted by using a simulated path of an inattentive driver. The highway curve and operational elements studied included vehicle speed, highway curve radius, length of curve, super-elevation rate, super-elevation runoff length, super-elevation runoff distribution, presence of spiral transition, and presence of downgrade, The study revealed two significant results: (a) the dynamic response of vehicles traversing a highway curve is sensitive to speed; and (b) the addition of spiral transitions to highway curves dramatically reduces the friction demand of critical vehicle traversals.
