Statistical release presenting road traffic estimates for Great Britain in 2015.
Annual estimates are mainly based on around 8,000 manual counts where trained enumerators count traffic by vehicle type over a 12 hour period. Traffic data are also collected continuously from a national network of around 270 Automatic
Traffic Counters (ATCs). In addition to counting traffic, the ATCs record some of the physical properties of passing vehicles which are used to classify traffic by type.
These two data sources are combined with road lengths statistics to produce the number of vehicle miles travelled each year by vehicle type, road category and region.
In 2015, the overall motor vehicle traffic volume in GB was
316.7 billion vehicle miles, almost 1% more than the previous high in 2007.
In 2015, traffic volumes for cars and motorcycles were broadly similar when compared to 2014, while HGVs and LGV’s showed increases of 4% each, and buses and coaches showed decreases of 5%.
In the last 10 years, traffic volumes for cars and LGV’s have increased (2% and 22% respectively) and has decreased for HGV’s (-7%) Motorcycles (-17%) and buses and coaches (-15%).Traffic, volume, vehicle miles. National statistics.
