Investigation of risk reduction for various safety treatments in different environments

Turner, Blair, Imberger, Kelly

Road Environment


ARRB Group are involved in an extensive range of research aimed at identifying the level of risk for different road stereotypes, and at the reduction in this risk resulting from changes in design standards and from remedial treatments. This Austroads funded research is designed to aid policy makers and practitioners in assessing risk and prioritising treatment on their roads.

This paper will present results from one part of the research program that explores the crash reduction benefit from various engineering based treatments. Twenty-one measures were assessed, and crash reduction values derived for different road environments. This work is based on extensive reviews of the literature, and as well as assessing the crash benefit expected from various treatments, methodological issues in deriving these values are also discussed.
