This document gives guidance on the analysis of scheme costs in transport appraisals.
In November 2014 this TAG unit was updated to provide guidance on how Network Rail costs should be treated and reported in appraisal following the decision to reclassify Network Rail as a central government body; and to align the GRIP stages equivalent to stages 1, 2 and 3 in table 7 with those given in TAG unit A5-3 rail appraisal.
The previous version of this unit was TAG unit A1-2 scheme costs, January 2014.
WebTAG provides information on the role of transport modelling and appraisal, and how the transport appraisal process supports the development of investment decisions and business cases.
