HC Deb 31 March 1998 vol 309 c496W
46. Mr. Kidney

To ask the Secretary of State for the Environment, Transport and the Regions what research he has commissioned into the effects on traffic volumes of reducing road capacity. [35491]

Dr. Strang

The Department of the Environment, Transport and the Regions, jointly with London Transport, considered the effect on road traffic volumes of roads which happened to be closed or have their capacity restricted. The study examined:

  1. 1) how traffic models of such capacity restrictions ought to be developed and
  2. 2) 60 or so cases where closures and restrictions happened—sometimes unexpectedly.

The results of both aspects of that study were published on 11 March in separate reports and a summary report entitled "Traffic Impact of Highway Capacity Reductions" is also available. A copy of the summary report has been placed in the Library of the House.
