Details

This document details the overall framework underpinning the analysis of wider economic impacts in transport appraisals.

The WITA software is in conjunction with this guidance to estimate the wider economic impacts of an appraisal.

TAG provides information on the role of transport modelling and appraisal, and how the transport appraisal process supports the development of investment decisions to support a business case.

This information was previously released in various 2014 and 2016 TAG guidance publications before being merged into this single publication.
