HC Deb 08 April 1971 vol 815 cc309-10W
Mr. Cormack

asked the Secretary of State for the Environment what level of traffice flow, expressed in passenger car units per 16-hour day, he normally considers as requiring the provision of a motorway standard route for inter-urban traffic.

Mr. Graham Page

The decision to provide a motorway depends upon a number of factors and is not related solely to the forecast level of traffic. However, in rural areas we would normally expect a forecast design year flow of at least 33,000 passenger car units for a 16-hour August day before providing a dual two-lane motorway or all-purpose trunk road.
