HC Deb 25 October 1967 vol 751 c490W
70. Mr. John Lee

asked the Minister of Transport if she will institute road traffic census procedures on all motorways and other principal roads for the purpose of comparing the volumes of traffic during peak and off-peak periods.

Mr. Carmichael

Traffic censuses on trunk roads and motorways have been taken periodically for many years. The last such census was in 1965.

A fresh census on motorways and trunk roads and on the new system of principal roads is being planned.
