Scheme Appraisal
In terms of scheme appraisal, the cost-benefit and environmental impact assessment methods set out in DMRB provide important inputs into the approach used to appraise road schemes, called the New Approach to Appraisal.

[edit] Timeline

When the DMRB was originally published in 1992 it only covered roads in England and Wales. Its remit was subsequently extended to include roads in Scotland and Northern Ireland. DMRB is managed by the Highways Agency on behalf of the agencies responsible for trunk roads in Scotland, Wales and Northern Ireland.
