HC Deb 29 July 1975 vol 896 c478W
Mr. Monro

asked the Secretary of State for the Environment what is the approximate traffic flow of vehicles per day on the Al and A74; and if he will give the number of fatal accidents per mile on these two dual carriageways in 1974 or the latest convenient year.

Mr. Carmichael

The traffic flow varies widely over the many sections of the A1; the average daily (16 hour) flow in August 1974 ranged from 12,000 to 35,000. The corresponding flow on the A74 was about 17,000. In 1974 the numbers of fatal accidents per mile of dual carriageway were 0.15 on the Al and 0.26 on the A74.
