- Road safety engineers and practitioners
- Asset managers prioritising investment
- Designers assessing proposed treatments
- Auditors validating Safe System alignment
Provides evidence-based scoring and ranking to support treatment selection, investment prioritisation, and network-wide decision-making.
Use SSTST when you need to:
Identify appropriate treatments for a specific road segment or crash pattern; compare treatment cost-effectiveness; build evidence-based cases for infrastructure investment; demonstrate Safe System alignment in project scoping.
The tool is delivered as a web application. Typical workflow:
Enter road context (type, speed environment, user mix); select crash types of concern; review ranked treatment options with Safe System scores; export to treatment registers or business cases.
