The reduction of collision injuries : past, present, and future.

The paper represents a distillation and analysis of collision injury cases collected by the UCLA Trauma Research Group from 1960-1969. Injuries are interpreted with relation to specific variables which are thought to represent important factors in collision injury causation and prevention. The Methodology is presented as one possible way to view transportation trauma in terms of factors which can be isolated and may lend themselves to manipulation in the cause of traffic safety.
