Version archive

Every published version is kept here. The live page (/) is always the latest; older versions are never overwritten.

• Current (live) — latest published
• v11 — peer-review revisions (John Catchpole, Road Safety Victoria): ANCAP alongside UCSR; FSI-crashes labelling; up-front SRS-vs-IRR clarifier; FSI-Equivalent reframed as a validated supplementary metric (under-reporting/speed caveats); systemic diagnose→screen precision (own aggregate crash history); traffic-volume & treatment-cost caveat; clarity and balance fixes
• v10 — AI Q&A widget: “Road Risk Explainer AI Assistant” (answers only from the page + its cited sources, independently verified); explainer content unchanged
• v9 — safety-science layer (SPFs/CMFs) added; vehicle-risk scope note; references + SEO
• v8 — page-view counter + crashstats.com.au home link
• v7 — integrity pass (collective FSI-based default; iRAP/KiwiRAP not AusRAP; "personal" standardised)
• v6 — AusRAP = Star Rating; collective/personal = complementary Crash Risk Mapping
• v5 — systemic redrawn as a method spanning both lanes
• v4 — retitled + at-a-glance concept map
• v3 — practitioner playbook
• v2 — corrected systemic-risk definition
• v1 — original explainer
