HC Deb 01 July 1993 vol 227 cc588-9W
Ms Walley

To ask the Secretary of State for Transport if he will list the traffic growth forecasts for England used by his Department for the periods 1963 to 1970, 1970 to 1980 and 1980 to 1990; and if he will give the actual traffic growth for those periods.

Mr. Key

Since it started to use national forecasts of road traffic in about 1970 the Department of Transport has used or made six principal forecasts. They are given for selected years in the table in index number form, with a base of 1968 = 100 for the earliest forecast, and with a base of the index of actual traffic compared with 1968 for the subsequent forecasts. The table also includes an index of actual traffic growth since 1968.

The index numbers are of the total of all motor vehicle traffic except two-wheelers, for Great Britain. After 1975 the forecasts were made in a range of low and high growth, and the two figures for each year reflect that range.
