This is a fansite for the Transport Analysis Guidance Website – WebTAG
The Department for Transport originally initiated the information found on this website to provide detailed guidance on the appraisal of transport projects and wider advice on scoping and carrying out transport studies.
More specifically, this is the place where you can find the Department for Transport’s information for the guidance on the conduct of transport studies. The guidance includes or provides links to advice on how to:
- set objectives and identify problems;
- develop potential solutions;
- create a transport model for the appraisal of the alternative solutions;
- and how to conduct an appraisal which meets the Department’s requirements.
The website also includes advice on the modelling and appraisal appropriate for major highway and public transport schemes.
The guidance should be seen as a requirement for all projects/studies that require government approval. For projects/studies that do not require government approval TAG should serve as a best practice guide.
The site originally brought together the Department’s existing documents, The Guidance on the Methodology for Multi-Modal Studies (GOMMMS) and associated supplements and errata, Applying the Multi-Modal Approach to Appraisal to Highway Schemes (The Bridging Document) and Major Scheme Appraisal in Local Transport Plans.
