To ask the Secretary of State for Transport what was the average number of vehicles per hour travelling on the A1 in each year from 1960 to date; and what is the projected annual rate for the next 10 years.

Mr. Peter Bottomley

The earliest year for which data are available is 1983.

Number
1983 900
1984 940
1985 990

These estimates are based on counts taken at different times and are subject to sampling errors. The A1 has been defined to include those sections designated as motorways.

The Department prepares forecasts of national traffic. Where specific trunk road improvements are being assessed, local traffic forecasts are prepared. Projections are not otherwise made for specific roads.
