Abstract
The study follows the Troy and Butlin concepts closely except in its treatment of the cost of fatalities, where an approach is adopted which results (1) in a lower value being placed on economic loss through a traffic fatality, and (2) lends itself to mass cost estimation more readily than the Troy and Butlin method. It was estimated that in 1969 there were about 475000 collisions of all types involving about 900000 damaged vehicles.
