TTM Control Design Assistant
Risk-based reasoning for temporary traffic management controls.
Establish the base dimension, understand what would increase it, know when a reduction is genuinely available — and keep the reasoning on the record.
- Dimensions come from a tested rule engine, never from free-form generation.
- Every answer carries its sources, assumptions and residual risk.
- Recommendations require competent reviewer acceptance. Nothing is approved here.
Supports planner judgement. Does not replace site-specific risk assessment or professional engineering judgement.
