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 major roads only. Explanatory notes (metadata) are available for each dataset, and in one combined note.
