The possibility for lowering the impact severity in roadside collisions is different compared to car-to-car collisions. This may have implication for the construction of roadside objects. The aim of this Swedish research was to study pulse shapes and influence on injuries in collisions with roadside objects compared to car-to-car collisions. The results from 119 real-life frontal impacts with recorded crash pulse recorders and the diagnoses from occupant injuries were analysed. It was found that in collisions with roadside objects the meanvalue of the average duration was longer compared to car-to-car collisions, and that the average acceleration at the beginning of the crash pulse seems to be lower in roadside collisions compared to car-to-car crashes.
