Environmental determinants on traffic accidents: an alternate model. Paper presented at the 53rd Annual Meeting of the Highway Research Board, Washington, D.C., January 1974.

A study concerned with the identification and quantification of environmental determinants of traffic accidents and with the construction of a conceptual model of traffic accidents based on environmental factors, is summarized. The analysis of data, derived from a sample of 135 road segments, indicates that the number of accidents on a road segment is best predicted from traffic volumes and accident rates, whereas accident rates are best predicted from the type of road, intensity of road frontage development, and percentage of population between 16 and 24 years old residing in the region.
