STAG involves the appraisal of generated options which could potentially address identified problems and opportunities against a range of criteria, including value for money. As such, the STAG Report provides the Strategic Business Case for options taken forward.
The completion of a STAG study and the production of the STAG Report should precede any application for planning consent or the production of development management Transport Assessments in support of developments. This ensures appropriate consideration and reporting of the transport issues relative to the proposal being developed. To this extent a STAG Appraisal is complementary to a Transport Assessment.
