Data on investment returns from transport schemes considered by the Eddington Study


Table of contents


Eddington Evidence Base

The Department for Transport is placing into public domain the evidence base of analysis provided to the Eddington Study as background for the strategic assessment of returns to transport investment. This represents just one of a number of sources considered by the Eddington Study. Other sources are referenced in the main study report.

The analysis was based on almost 170 detailed appraisals for a range of interventions including road and public transport schemes in a variety of locations across the UK. In addition, further modelling of almost 20 interventions, using more detailed local models, was undertaken(1).

For each scheme we report the New Approach to Appraisal Benefit to Cost Ratio (NATA BCR) from the Department's view and (where applicable) the Value for Money category. In a few cases the Department has taken a more cautious view than scheme promoters on the NATA BCR, particularly where it was confident about the Value for Money category. Value for Money is a more complete measure of the returns to investment and includes an assessment of environmental and social impacts. The assessment - specifically non-monetised impacts - is challenging. The best available evidence is used, but there may be uncertainties which cannot be conveyed in a single category. As such results must be interpreted with some caution.

This evidence represents the data available to the Eddington Study as of May 2006. The scheme appraisals were carried out at different stages in the approval process - either at Programme Entry or later approval stages. A number of schemes in the list were not approved for Programme Entry and are not being progressed. The Eddington Study has not generally sought to undertake Value for Money assessments of schemes which have not already been assessed during the course of Departmental business.

A number of additional schemes were identified during the course of the Eddington Study (See 'External Sources below). It should be noted that some of these have not been fully developed and the costs and risks in particular have not been assessed to the level of confidence seen in other transport projects. As such these BCRs should be interpreted as only illustrative of the potential returns.

This evidence has been used to provide a strategic analysis of the potential returns from different types of intervention such that the Eddington Study has focused on identifying long-term priorities (post-2015). Neither this evidence base nor analysis attempts to represent the views of either DfT or Sir Rod Eddington regarding current decisions or specific priorities. Value for Money is only one of a range of factors ministers must consider when taking decisions, others include:

We have not published information relating to one scheme which has subsequently been considered for the first round of the Productivity Transport Innovation Fund As announced on Monday 18th December the Department will be working with promoters to develop these schemes. It would be inappropriate to publish this information in advance of these discussions and a final decision.
