Download street-level traffic figures for all regions and local authorities
Two sets of traffic data are available to download:
AADF figures give the number of vehicles that will drive on that stretch of road on an average day of the year. For information on how AADFs are calculated, see the guidance on the Traffic Statistics pages on GOV.UK.
AADF figures are presented as: Units = vehicles per day
Traffic figures give the total volume of traffic on the stretch of road for the whole year, and are calculated by multiplying the AADF by the corresponding length of road and by the number of days in the year (i.e. one vehicle travelling one mile each day for a year would equal 365 vehicle miles).
Traffic figures are presented as: Units = thousand vehicle miles
The traffic figures are produced for each junction to junction link on the major road network for every year, and are referred to as “street-level” on this website. Both “AADF” and “Traffic” data are available for major roads.
A sample of points on the minor road network are counted each year and AADFs for these points are available to download only.
