The Department for Transport’s road traffic statistics team are conducting a review of the traffic estimates for Great Britain. This overview document gives an introduction to the review, and progress on each stage of the work. Alongside the overview document on this page, detailed reports on each project will be published as the projects are completed.

The aim of the review is to ensure robust traffic estimates continue to be produced, seeking innovation and greater value for money in their production while protecting user needs.

The focus of the review is:

  • a detailed review of the current methodology for producing quarterly and annual traffic estimates, which includes both methodological improvements plus any efficiencies in sampling and analysis
  • investigating alternative data sources and, if appropriate, determining robust methods for their use in producing traffic estimates

For the annual and quarterly road traffic estimate publications, see road traffic statistics.
