Since the original publication of 2014 road traffic estimates in May 2015, a minor processing error has been discovered. This has affected the traffic estimates for seven (out of over 18,000) junction-to-junction links of motorway and ‘A’ road.
At the national level, the impact of the revisions on road traffic estimates is negligible. Traffic estimates for five local authorities have changed slightly as a result of correcting the processing error, and the relevant tables containing local information have been updated. The local authorities affected are Newport, Monmouthshire, Caerphilly, Warwickshire and Birmingham.
If you would like to know more about these revisions, please contact the road traffic statistics team.
Since the 1950s, the long term trend in the volume of road traffic has been one of growth, peaking at 314.1 billion vehicle miles in 2007. Following this peak, motor vehicle traffic then fell for three consecutive years; the first consecutive annual falls since traffic records began. Between 2010 and 2013, traffic volumes were broadly stable, but have once again shown growth between 2013 and 2014, rising by 2.4% to reach 311 billion vehicle miles.
