A GENERAL APPROACH TO ESTIMATING FRONTAL IMPACT COLLISION SPEEDS

This paper shows that the specific energy absorption characteristics of the car population in frontal collisions can be represented by a single equation which has a coefficient of determination of 0.76. Comparison of predicted and actual Delta V's when using this relation shows that the equation yields similar accuracies to CRASH 3. When the energy absorption characteristics of individual cars are known, the resulting predictions are superior to both the derived relation and to CRASH 3. A simple method is derived to estimate the energy absorption of the missing vehicle, when only one of the collision partners is available for measurement.
