Abstract:

The potential for hazardous events occurring to vehicle occupants after a redirection from a longitudinal barrier has not been adequately addressed. Very few studies are available which indicate the frequency and severity typical for vehicles striking another roadside object after an initial collision with a longitudinal barrier system. Four accident data bases are presented and the findings imply that the most harmful event in terms of occupant injury is often the second or third collision of the errant vehicle.
