asked the Secretary of State for Transport what was the total cost of funding the Transport and Road Research Laboratory in 1979, 1980, 1981 and 1982; and what was the expenditure on heavy goods vehicle projects.

The gross TRRL spend and expenditure specifically on heavy goods vehicle projects over the last four financial years at outturn prices is:

	1978–79	1979–80	1980–81	1981–82
	£ million	£ million	£ million	£ million
TRRL	10·4	11·5	14·1	12·7
HGV Projects	0·59	0·44	0·71	0·93

This does not include the cost of projects of a more general nature on road design, safety and traffic engineering which also contribute to a better understanding of the issues relating to heavy goods vehicles.
