Abstract
The trend of automobile occupant fatalities from 1950 to 1968 was studied. The influence of factors as vehicle age, improved door locks, small cars, seat belt use, driver age, and speed was estimated on the basis of past studies. The relation of 20 other factors to this trend was explored by regression analyses. The number of automobiles involved in potentially fatal accidents was projected to 1968.
