Transport appraisal and modelling strategy: informing future investment decisions

The Department for Transport’s (DfT’s) appraisal framework aims to provide as full a view as possible about the wide range of impacts transport has on the economy, environment and society. Our guidance on how to conduct transport appraisals, WebTAG, draws on best practice in government, academia, and industry. We aim to ensure that it reflects the latest evidence and appraisal methodologies.

This consultation seeks views on the main themes and priorities for developing the evidence base underpinning our appraisal guidance over the next 5 years. We are also seeking views on how we can make the guidance more user friendly.
