CASE STUDIES CONSIDERED AS RETROACTIVE EXPERIMENTS

The conclusions of this analysis are: (1) Occupants of vehicles who were not wearing any restraint device were involved in crashes which had a slightly higher expected severity. (2) Seat belts and upper torso restraints each contribute an increment of occupant injury severity reduction, even after the differences in crash severity have been controlled. An important application of this approach involves the use of an injury prediction model to compute an expected injury conditional on crash severity. The expected injury is subtracted from the observed to yield an injury statistic which is corrected for differences in crash severity. This corrected injury, (i.e. residual injury = observed injury minus predicted injury), can then be used to compare, for example the effectiveness of various vehicle components with respect to injury severity reduction.
