The Highway-Vehicle-Object Simulation Model (HVOSM), a computer model describing an automobile and capable of predicting the dynamic response of the automobile traversing selected terrain, was used to study the behavior of a standard size automobile traversing embankment side slopes at various speeds and departure angles. The accelerations obtained were used to compute a severity index which was then compared with a similarly computed severity index (from actual crash data) of a vehicle impacting a W-beam guardrail with posts on 6 ft 3 in spacing. An Equal Severity Curve was than developed which can be used as a guardrail installation criteria, determining if guardrail should be used to prevent an automobile from going over a selected embankment slope.
