GB Road Traffic Counts

The Department for Transport collects traffic data to produce statistics on the level of traffic on roads in Great Britain.

Summary statistics of road traffic are published on an annual and quarterly basis at https://www.gov.uk/government/collections/road-traffic-statistics

The most user-friendly method to access street-level road traffic estimates, with an interactive mapping tool, is via https://roadtraffic.dft.gov.uk

Data are available for each junction to junction link on the major road network (motorways and A roads). Data are also available for the sample of points on the minor road network (B, C and unclassified roads) that are counted each year, and these counts are used to produce estimates of traffic growth on minor roads.

The data are produced for every year and are in three formats: a) the raw manual count data collected by trained enumerators; b) Annual Average Daily Flows (AADFs) for count points on major roads and minor roads; and c) traffic figures for local authorities and regions.

An explanatory note (Road traffic data metadata) is available below. A description of how annual road traffic estimates are produced is available at: https://www.gov.uk/government/publications/road-traffic-statistics-guidance
