The accuracy of the CRASH computer program was evaluated in terms of its ability to estimate impact speed. A comparison of the results from CRASH2, CRASH 3 and EDCRASH were presented along with measured results from twelve staged collisions. Statistical analysis of these results revealed the impact speeds estimated by these CRASH programs were within - 6 to +7 percent of the combined impact speeds at a 95 percent level of confidence.
