HC Deb 17 April 1980 vol 982 cc685-6W
Mr. Whitehead

asked the Minister of Transport if he will list the statistical sources which he will use when planning new roads, if no question on car or van ownership is included in the 1981 census.

Mr. Fowler

Information on car availability at the national and regional level is obtainable from voluntary surveys such as the general household survey, the family expenditure survey, the national dwelling and housing survey, and the national travel survey.

These surveys, together with the data collected in road traffic censuses, the records of the car stock held at DVLC Swansea and information from local highway authorities, provide an adequate basis for future traffic forecasts when planning new roads.
