Road Safety Engineering Risk Assessment ? Recent and Future Research
Keywords: Road Environment
Submission Date: 2006
ARRB has been conducting an extensive range of research aimed at identifying and measuring
the level of risk associated with different road stereotypes, and at the reduction in this risk
resulting from changes in road 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 so as to achieve optimal crash risk reduction for the
Research topics include the development of crash rates databases, investigation of risk reduction
for safety treatments in different environments, the implications of varying design standards,
information on local road safety schemes, use of crash cost as an indication of severity, an in-
depth investigation of rural head-on, intersection and run-off-road crashes, the safety implications of road deterioration, an investigation of crash risk migration, and the effect of using multiple countermeasures.
This paper provides examples of the results from some of this research.
