Techniques
Risk Assessments
Risk Assessments are structured techniques for identifying, quantifying and prioritising road-safety risks across a project, road, corridor or network. They draw on crash history, exposure data, road-geometry and roadside-hazard inventories, and proactive risk modelling tools such as AusRAP to produce a defensible ranking of risk by location and crash type, allowing limited treatment funding to be directed where it will save most lives and prevent most serious injuries.
Risk Assessments inform a wide range of downstream techniques, including Safe System Assessments, Road Safety Audits, and Network Safety Plans. The Austroads Guide to Road Safety provides the Australian methodology; the technique is most powerful when proactive risk modelling is combined with reactive crash analysis, so high-risk locations that have not yet generated visible crash history are still identified. Outputs typically include a risk register, a heat-map of risk, and a treatment-priority schedule with cost-benefit signposting.
