The Standing Advisory Committee on Trunk Road Assessment (SACTRA) is an independent committee appointed by the Secretary of State for Transport to advise on issues related to the appraisal of trunk roads.

The National Transport Model

The Department has developed a National Transport Model (NTM) as an analytical and policy-testing tool, providing a systematic means of comparing the national consequences of alternative national, or widely-applied local, transport policies.
