Answer: Mrs. May: To ask the Secretary of State for Transport what percentage of the road network in (a) England and (b) Great Britain was at 100 per cent. or greater stress in (i) 1996, (ii) 2000, (iii) 2001 and (iv) 2002 to date. [71340] Mr. Jamieson: [holding answer 19 July 2002]: A stress map for the English Trunk Road network was published by the Department for 1996 based on actual traffic counts. It showed 3 per cent. of the network was operating above 100 per cent. stress and 10 per cent. of the network between 80 per cent. and 100 per cent. A map based on estimated 2000 traffic flows was included in the published 10-Year Plan. The Plan reported that 7 per cent. of the network was operating above 100 per cent. stress and 13 per cent. of the network between 80 per cent. and 100 per cent. More recent data is not available. Data for the whole of the English road Network and for Great Britain is not available. The `stress level indicator' is not a precise measure and is intended for illustrative purposes at the National level.
