To ask the Secretary of State for Transport what the level of congestion was on the interurban trunk road network in (a) 2000, (b) 2001 and (c) 2002. [114774]

[holding answer 20 May 2003]: Congestion on inter-urban trunk roads can be measured in a number of different ways. One option, used in the Department's 10-Year Plan, is to take the difference between actual average speeds and estimated speeds achievable in the absence of congestion. Full details of the methodology are available on the DfT website.The estimated level of congestion on inter-urban trunk roads in England, measured in this way, was 3.2 seconds per vehicle kilometre in 2000. No equivalent data are available for 2001 and 2002.
