Applying the Multi-modal New Approach to Appraisal to Highway Schemes
5. DMRB and GOMMMS Correspondence
Tables
5.1 Introduction
5.1.1 This document is focused
on the production of a NATA appraisal at Plan
Level equivalent to a DMRB Stage 3 assessment.
This assumes a high level of detail can be
achieved and the information available from
DMRB is of an appropriate level of detail.
However, less detailed information is available
at DMRB Stages 1 and 2, thus the NATA appraisal
method will need to reflect this and it is
likely that assumptions will need to be made
as appropriate. Where this is necessary, analysts
should bear in mind the NATA principle that
judgement should be based on evidence where
possible and should ensure that all assumptions
are justifiable and fully documented. Some
advice is given in the following Objectives
chapters, Chapters 7-11, with regard to Stage
1 and 2 appraisals, by sub-objective.
5.1.2 The structure of the GOMMMS
Appraisal Summary Table (AST) is given in
Annex A. The AST is a one-page summary of
the effects of a scheme/Plan for use by decision-makers,
explained further in Chapter 6.
5.2 Correspondence Tables
5.2.1 To assist the analyst,
a correspondence table has been produced for
the Environment Objective (Table 5.1), which
illustrates for each sub-objective the worksheets
that need to be completed as part of the GOMMMS
appraisal and the source of the information
from the DMRB assessment and other related
sources, where there is a relevant equivalence.
For those sub-objectives that are introduced
by the new approach to appraisal, there is
no equivalence in DMRB.
5.2.2 Tables 5.2 to 5.5 provide
the correspondence tables for the Safety,
Economy, Accessibility and Integration Objectives
respectively, including references to other
sources of information than DMRB where relevant.
