This file contains the annual traffic (otherwise known as volume of traffic) on each link of
the major road network. This is calculated by multiplying the AADF by the corresponding
length of road and by the number of days in the year. So one vehicle travelling one mile a
day for a year would equal 365 vehicle miles. Traffic figures are presented in thousand
vehicle miles, so a count point with a traffic volume of 20,000 vehicle miles in one year will
be presented as 20.0. Traffic volumes for major roads can be added together to the
vehicle mileage for that areas major roads. A description of how annual road traffic
estimates are produced is available at https://www.gov.uk/government/uploads/system/uploads/attachment_data/file/270083/contents-page.pdf.

AADF figures are produced for each junction to junction link on the major road network for
every year. A description of how annual road traffic estimates are produced is available at
https://www.gov.uk/government/uploads/system/uploads/attachment_data/file/270083/contents-page.pdf.

An AADF is the average over a full year of the number of vehicles passing a point in the
road network each day. Major roads include Motorway and A-class roads. For
methodological reasons, the AADFs for different count points should not be added
together.
