Road traffic statistics
The latest estimates of road traffic in Great Britain. This web page provides provisional quarterly road traffic estimates and more detailed annual estimates. The annual estimates are also provided at Local Authority level.
Please note that free flow vehicle speeds statistics are now published separately.
Special note: Traffic estimates for major roads are based on a census of all major roads. However traffic estimates for minor roads are estimated by calculating growth rates from a fixed sample of count points on the minor road network. Every ten years or so traffic estimates for minor roads are benchmarked against a larger data sample, and adjusted if necessary. The last time this was done was for 1999, and in 2008 and 2009 a larger sample was drawn so that the benchmarking exercise could be repeated and the traffic estimates recalibrated. Data from those larger samples will be used to recalibrate the traffic estimates for 2009, as a new benchmark point. This could mean that the 2010 Annual traffic statistics may need to be adjusted to take account of the implications of the new benchmark for 2009. We anticipate publishing the outcome of this exercise, along with any revisions to traffic estimates from 1999 to 2010, early in 2012.
