Samenvatting
This paper applies on-the-road crash data and computer modelling to clarify opportunities for reducing rollover crash casualties. Countermeasures to reduce rollover casualties include increased belt use, and technological interventions to prevent ejection and to reduce the severity of body contacts with the vehicle interior. The vehicle speed immediately prior to the rollover is a pivotal predictor of rollover crash severity. The number of vehicle quarter turns, the vehicle damage, and the roll rate are also predictors, and are strongly related to the initial vehicle speed. Computer simulators described suggest that the severity of the tripping acceleration may also have a strong influence on occupant ejections and injuries. (A)
