The research examined through computer simulation, the effect of road roughness on tire-pavement forces in braking and cornering on a road of skid number 50. In addition to the force information, braking performance, measured by stopping distances, and cornering performance, measured by stability factor which indicates understeer, were investigated. Vehicle performance was accessed on five road surfaces: smooth, two actual recorded road profiles, and two periodic profiles. Two vehicles were simulated - (1) 1971 Dodge Coronet passenger car, and (2) 1974 White Road Boss single unit truck. The White truck was loaded to maximum gross weight. The simulation utilized was the Hybrid Computer Vehicle Handling Program (HVHP) which is a nonlinear representation of four wheeled vehicles.
