An accident evaluation analysis. Paper presented at the 53rd Annual Meeting of the Highway Research Board, Washington, D.C., January 1974.

An analysis of accidents to evaluate the effectiveness of traffic controls at intersections in an effort to develop new traffic control warrants, is presented. A quantitative means of comparing accident histories at intersections is discussed. An accident evaluation index is computed by using a percentage distribution of accidents by the following types: pedestrian, right-angle, rear end, left-turn, and all others.
