Guides

Part 2 of the Guide to Road Safety covers the Safe Roads element of the Safe System — designing, assessing and treating road infrastructure so that the network is forgiving of the mistakes road users inevitably make. It draws together proactive risk-assessment methods, crash-type analysis and treatment selection so that infrastructure investment is directed to where it will prevent the most serious trauma.

Topics include network safety assessment and risk rating, the relationship between road function, layout and crash outcomes, and the selection of Safe System-aligned treatments for the main fatal and serious-injury crash types — run-off-road, head-on, intersection and vulnerable-road-user crashes. It links closely to Part 3 (Safe Speed) and Part 6 (Road Safety Audit), reflecting that infrastructure, speed and assessment work together.
