Injury Risk Functions in Frontal Impacts Using Data from Crash Pulse Recorders

This paper reports on a study that used data from on-board crash pulse records to determine crash severity and thus evaluate injury risk functions in frontal impacts. The authors stress that knowledge of how crash severity influences injury risk in car crashes is essential in order to create a safe road transport system. They analyzed data from 489 frontal car crashes (including 26 models of four car makes) with recorded acceleration-time history. Injury risk functions for restrained front seat occupants were generated for maximum AIS value of two or greater (MAIS2+) using multiple logistic regression. The authors considered a number of crash severity parameters, including change of velocity, mean acceleration and peak acceleration. They also factored in the influence of occupant age and gender was investigated. The results showed that small changes in crash severity may have a considerable influence on the risk of injury. Mean acceleration, followed by change of velocity, was found to be the single variable that best explained the risk of being injured (MAIS2+) in a crash. All three crash severity parameters were found to predict injury better than age and gender. However, age was an important factor: occupants over 60 years of age have more than 60% higher risk for MAIS2+ injuries compared to younger occupants.
