THE RELATIONSHIP BETWEEN VEHICLE ROOF STRENGTH AND OCCUPANT INJURY IN ROLLOVER CRASH DATA

This paper evaluates the effect of vehicle roof strength (as measured in FMVSS 216) on severe occupant injury using police-reported motor vehicle accident data from Florida, Texas, Michigan, and North Carolina. The paper also evaluates the effect of vehicle shape as measured by the overall height-to-track width ratio on severe occupant injury in rollovers. The validity of the state data was verified using NASS matched case data. The data was controlled for accident severity, restraint use, and driver demographics. Based on 60,758 single vehicle rollover accidents in the four states, conclusions were: There is no relationship between vehicle roof strength-to-weight ratio and the likelihood of severe injury for the vehicles studied. There is no relationship between the roof strength-to-vehicle-weight ratio and the likelihood of severe roof damage for vehicles involved in rollovers. There is a strong relationship between vehicle shape and severe roof damage for vehicles involved in rollovers. There is a weak relationship between vehicle shape and severe occupant injury.
