Volume 477: debated on Thursday 12 June 2008

To ask the Secretary of State for Transport what account is taken of the time taken for journeys by different modes of transport when appraising transport schemes. (210055)

The Department for Transport appraises proposed transport schemes using the New Approach to Appraisal (NATA). Journey time impacts across all modes of transport are included in every NATA appraisal, and form an important element of the benefits of transport interventions.

For the purpose of valuing changes in the duration of journeys NATA distinguishes between working, commuting and leisure trips. This reflects a large body of evidence on the values of time spent travelling. The values used in appraisal are provided by the WebTAG resource available at:

Most journey time savings typically accrue to people who are travelling in their own time, and are valued at either £5.04 per hour or £4.46 in 2002 prices, depending on whether time is saved from a journey to work or another destination. This is irrespective of the mode used.

Transport schemes also reduce times taken for work-related journeys. These benefits are valued according to the average labour costs of individuals who travel by different modes of transport. The average value of working time across all working persons is £26.73 in 2002 prices. Further details of the values of working time applied in transport appraisals are set out in table 1 in the transport analysis guidance unit linked to above. A copy of the table follows. These do differ by mode: evidence indicates that business travellers are selective in the modes used during work, with the most productive business trips using taxi, with rail and underground also being of high value.
