Abstract
This Statistical Release presents the speed of traffic in free flowing conditions on roads in Great Britain during 2010. These statistics provide insight into the speeds at which drivers choose to travel and their compliance with speed limits, but should not be taken as estimates of actual average speed across the road network. These estimates are based on traffic speed data collected from a sample of 96 Automatic Traffic Counters (ATCs) from a national network of around 180 ATCs. This sample was deliberately chosen to include ATCs located where external factors which might restrict driver behaviour (including junctions, hills, sharp bends and speed enforcement cameras) are not present.
