Techniques
Crash Analysis & Investigations
Crash Analysis & Investigations is a family of evidence techniques that turn crash data into actionable insight for road designers, asset managers and policy makers. It ranges from individual fatal-crash investigations that reconstruct contributing factors at a single site, through cluster and corridor analyses that identify recurring patterns, to whole-network statistical analyses that benchmark a jurisdiction against its peers and against its Vision Zero trajectory.
The technique relies on quality crash data, exposure data and contextual road and traffic information. Outputs feed directly into Safe System Assessments, Network Safety Plans and treatment-selection decisions; they also support strategic communications and case-making with funders. The Austroads Guide to Road Safety Part 8 sets out crash analysis methods and reporting conventions used by Australian and New Zealand road agencies, and includes guidance on dealing with under-reporting and other crash-data quality issues.
