The purpose of this study is to attempt to quantify the differences between CRASH3 generated velocity change (ΔV) as used in the National Automotive Sampling System - Crashworthiness Data System (NASS-CDS) and measured velocities in actual frontal crash tests. An appropriate factor is then applied to ΔV in NASS to estimate an adjusted ΔV distribution based on these differences. A substantial change to the velocity distribution in NASS-CDS will have a significant bearing on the estimates of lives and injuries affected by any changes to the impact velocity for the frontal crash test in FMVSS No. 208 or other rulemaking decisions.
