This review of the evidence of travel change behaviour can be used:

  • to help make the case for new investment, in bids or business plans.
  • to inform any re-assessment of existing programmes so that decisions can be based on the best evidence of effectiveness and value.
  • as a benchmark to compare the effectiveness of local programmes with published evaluations and evidence.
  • to encourage more sharing of evidence about what works.
  • to act as a focal point for new evidence, with annual updates.

Key messages include:

  • Travel behaviour change measures can provide very high benefits compared to costs, when measured by WebTAG, the Department for Transport’s method for evaluating transport investment.
  • Changing how we travel can reduce the need for expensive infrastructure.
  • Behaviour change measures can be implemented much more quickly than infrastructure projects.
  • All measures achieve genuine carbon reductions (from 5kgs to 1500 kgs per person per year).
  • Greater impact is achieved from careful targeting of people likely to change their behaviour combined with multi-measure programmes across age groups.
