Economic analysis of treatments proposed to reduce the number and/or the severity of crashes occurring at 'blackspots' require cost estimates of crashes by road user movement code. As these treatments are proposed in different speed environments, the cost estimates need to be for different speeds in the range from 50 to 110 kilometres per hour. Similarly, for major road projects, where road crash rates per vehicle kilometre and an average cost per crash are used to estimate total crash costs before and after project implementation, it is desirable that the cost per crash be available for generic road types at each speed in the range from 50 to 110 kilometres per hour. These average costs per crash should be derived from estimates of costs per person killed or injured plus the damage costs either per vehicle involved or per crash. This paper describes the method used to estimate per crash costs by road user movement code by speed limit and the per crash cost by generic road type by speed limit from costs per person injured and damage costs per crash.
