[79637] Mr. Jamieson: Surveys of average traffic speeds were carried out in London until the year 2000 by the Department for Transport. Central, Inner and Outer London were surveyed in turn, and Central London was covered in 1997 and 2000. Figures are not held specifically for the period 07:00 to 18:30. However, in Central London the average morning peak (07:45 to 09:15) speed during 1997 was 10.0 mph and in 2000 it was 9.9 mph. Since 3 July 2000, Transport for London have taken over responsibility for running the London speed surveys, as well as estimating the impact of congestion charging on traffic speeds in London from February 2003.
