AN INVESTIGATION OF THE JOINT INJURY DISTRIBUTION OF BELT AND UNBELTED DRIVERS IN AUTOMOBILE ACCIDENTS

Using 1973 and 1974 accidents in North Carolina, a theoretical joint injury distribution of belted and unbelted occupants is constructed and analyzed. This bivariate distribution corresponds to a theoretical setup where each real accident has its imaginary twin 'occurring' independently under the 'same' conditions. In one of the cases, the occupant is belted while in the other case he is not. To form such 'twins,' all matches are created between belted and unbelted drivers within similar crashes (i.e. within a given cell out of 396) as determined by car size and model year, TAD area and severity and by occupant's age. The obtained bivariate injury distribution was then weighted to correspond to the distribution of the reference population over the 396 strata. The corresponding shift in the injury distribution is then examined.
