asked the Secretary of State for Transport what traffic surveys he has carried out on routes across the Peak Park between east and west, and mainly Manchester and Sheffield; and if he will tabulate his estimates of the extra burden falling mainly on the Peak Forest and Woodhead routes due to the complete or partial closure of Nan Tor and Snake Pass for each quarter of 1978 comparing the position with the previous five years.
Origin and destination and volumetric surveys on all routes lying between Halifax and Derby were carried out before 1973. Subsequently random counts have been made on A628 and other routes. Traffic on M62 is monitored continuously. No estimate is available of traffic transfers due to closures at Nan Tor or Snake Pass.
