Volume IV of this document describes and evaluates computer reconstructions of the twelve staged collisions presented in Volumes II and III. Results of the CRASH II program were judged on their degree of correspondence with the measured impact speeds and changes in velocity. Reconstructions using the SMAC program were assessed on the basis of the accuracy of the predicted final rest positions, damage dimensions, and changes in velocity. On the whole, the results from both the reconstruction programs were satisfactory. Recommendations that are made include: 1) to update representative values of vehicle characteristics used in the CRASH II program, 2) to add a stationary vehicle option to the CRASH program, 3 to simulate hard points and corner effects in the SMAC program, and 4) to provide an option to input tire cornering stiffness time history data in order to simulate weight transfer effects.
