EXTENSIONS AND REFINEMENTS OF CRASH COMPUTER PROGRAM PART III{ EVALUATION OF THE ACCURACY OF RECONSTRUCTION TECHNIQUES FOR HIGHWAY ACCIDENTS

An analytical was performed with the objectives of (1) development of an "obstacle course" of well documented, staged collisions representative of frequently occurring accident configurtions and (2) determination of the reconstruction accuracies of the automatic iteration version of the SMAC* (Reference 1) and of the simplified CRASH** (Reference 2) computer programs. It had been initially estimated that twenty staged collisions could be selected for this purpose. Progress toward achievement of the stated objectives was impeded by the fact that most available results from staged collisions were found, on close examination, to be unsuitable for the intended use. For this reason, the usable reconstruction results of the study were limited to only four examples. It should be noted that even the four selected examples have shortcomings as "standard", well defined and representative accidents. Also, further development of the automatic iteration version of the SMAC computer program was found to be necessary to achieve the reported convergent solutions for axial collisions. It is concluded that an urgent need exists for realistic stage collision experiments to permit quantitative determinations of the accuracies of reconstruction techniques. The limited results achieved within the present study are considered to be indicative of very attractive levels of attainable accuracies.
