Abstract
This is the Final Report on a two-year statistical analysis of the data collected in the National Crash Severity Study. Statistical models were developed to relate the probability of a severe injury to independent variables such as delta v (the instantaneous change in velocity of the vehicle) and occupant age. Models were developed separately for various subsets of front and side impacts. Various clinical studies which were reported separately, are summarized in this report. These studies address the existing literature, side impacts, lower extremity injuries, eye injuries, and neck injuries. The application of the NCSS data to accident analysis models, which estimate the benefits of improved occupant protection systems, is also discussed.
