The Department for Transport is proposing major changes to its transport scheme appraisal guidance - known as WebTAG - with plans to make the system more flexible and to integrate wider economic analysis.
The Department
launched a consultation on the proposed changes, which are the result of a two year review with input from academic experts and stakeholders. The WebTAG appraisal and modelling guidance sets out the Department’s evidence base for understanding and valuing the impacts of transport investments.
This include wider economic benefits, which are the ‘the additional benefits (or disbenefits) that can arise as the impact of transport improvements is transmitted into the wider economy, beyond those businesses and passengers that are directly affected by the transport change’.
The Department aims to produce updated guidance that is robust and based on the best available evidence and ‘improves the clarity of methodologies and explanations’.
The main changes are:
-
A new requirement for scheme promoters to produce a context specific economic narrative that sets out the transmissions mechanisms through which transport investment will impact the economy and achieve the stated economic objectives.
-
Greater clarity on the relationship between the measures of benefits used in appraisal (welfare) and economic metrics such as GDP or GVA and employment.
-
A stronger focus on additionality and displacement in the analysis and reporting of economic impacts.
-
Greater flexibility to use new modelling and valuation approaches to supplement standard appraisal methods.
-
Regeneration impacts have been integrated into the assessment of wider economic impacts.
