HC Deb 15 November 1972 vol 846 cc142-3W
91. Sir D. Walker-Smith

asked the Secretary of State for the Environment what weighting is given to the volume of container traffic in cost benefit studies in regard to highway projects.

Mr. Speed

In appraising road projects and weighting given to heavy goods vehicles, including container traffic, varies greatly according to the existing road conditions, the composition of the traffic, and the time of day at which the bulk of the heavy traffic moves. Since this is a complex matter, I shall be writing to my right hon. and learned Friend.
