Road Statistics 2006: Traffic, Speeds and Congestion

This new annual bulletin brings together statistics that in previous years had been published in four separate reports. The DfT titles that have been replaced are:

  • Road Traffic Statistics (annual bulletin)
  • Vehicle Speeds in Great Britain
  • Traffic Speeds in English Urban Areas
  • Traffic Speeds on English Trunk Roads

The bulletin includes the first release of National Statistics on 2006 Road Traffic in Great Britain and the 2006 Urban-Areas Speed Survey. The bulletin also includes further information on Free-Flow Vehicle Speeds (first results were published in April), historic inter-urban speed survey results and experimental congestion statistics. 

The bulletin provides a detailed breakdown of the figures, including:

  • Traffic estimates disaggregated by vehicle type, type of road and Government Office Region;
  • Average daily flow of vehicles over a year shown by type of road, Government Office Region and for particular sections of motorway. It also includes an analysis of the seasonal and daily peaks in traffic flow;
  • Details of road lengths;
  • Vehicle speeds in free flow conditions, and the proportion of vehicles exceeding the speed limit, by vehicle type and road type.
  • Congestion, as measured by delay on the slowest 10% of journeys, on the Inter-Urban Road Network.
  • Traffic speeds in the 18 largest urban areas in England (excluding London).
