CAR-TO-CAR IMPACTS: COMPUTERIZED CRASH RECONSTRUCTION

This paper explores the use of a relatively new tool for accident reconstruction - Simulation Model of Automobile Collisions (SMAC). This study is limited to the reconstruction of side impact collisions in which two passenger vehicles are involved. The need for redesigning vehicles based on an understanding of this crash condition is amply demonstrated by the fact that 28% of passenger car occupant fatalities and 41% of passenger car occupant injuries are caused by side impacts. The results obtained during this study are (a) the development of a methodology for data analysis and (b) a relation between crash severity and injury causation. The results are based on a small sample of cases from the Multidisciplinary Accident Investigation (MDAI) file and hence, definitive statistical conclusions are not possible. However, patterns are apparent and suggest reltions between crash severity and injury causation. The results are based on a small sample of cases from the Multidisciplinary Accident Investigation (MDAI) file and hence, definitive statistical conclusions are not possible. However, patterns are apparent and suggest relations between accident parameters and occupant injuries. These suggested relations are discussed and interpreted. The first section of the paper provides a brief description of the SMAC program and describes its use. This is followed by a discussion of the selection process for the cases which have been reconstructed. The final sections of the paper describe the reconstruction and the results. /Author/
