HC Deb 08 July 1988 vol 136 c796W
Mr. Tony Banks

To ask the Secretary of State for Transport what information he has about the total annual cost arising from traffic congestion in London in each of the past five years.

Mr. Peter Bottomley

There is no generally agreed basis for calculating total annual congestion costs in London. The available information about traffic volumes and speeds is published annually in a statistics bulletin entitled "London Traffic Monitoring". Copies have been placed in the Library.
