Interactions of occupant age, vehicle weight, and the probability of dying in a two-vehicle crash.

Previous studies have considered the likelihood of injury and fatality to car occupants as a function of their own vehicle's weight and of the other vehicle's weight (for two-vehicle collisions). Since occupant age has an effect on the likelihood of injury or fatality, and since it varies strongly with car size, this study is intended to determine these relationships in a set of mass accident data while controlling for occupant age.
