abstract="He highway-vehicle-object simulation model, a computer model that decribes an automobile and is capable of prediciting the dynamic response of the automobile traversing selected terrain, was used to study the behavior of a standard-sized automobile traversing embankments side slopes at various speeds and departure angles. The accelerations obtained were used to compute a severity index that was then compared with a similarly computed severity index (from actual crash data) of a vehicle impacting a w-beam guardrail with posts on 61/4-ft spacing. An equal-severity curve was then developed that can be used as a guardrail installation criterion. /author/<p /><p>Language: en</p>",
