Current status: Answered by Lewis Macdonald on 16 December 2002
To ask the Scottish Executive, further to the answer to question S1W-31634 by Lewis Macdonald on 28 November 2002, whether it has any figures for the percentage of commercial vehicles and HGVs using the A9 trunk road between Perth and Inverness and, if so, how these figures compare with the national average for non-dual carriageway trunk roads.
Yes, the Scottish Roads Traffic Database (SRTDb) has two Automatic Traffic Classifier Sites (ATCS) located on the A9 between Perth and Inverness at Birnam and Tomatin. The percentage of HGVs at these locations is 9.5% and 14.26% respectively.These figures are based on data collected for the 12-month period between December 2001 and November 2002.Information on national average HGV percentages for non-dual carriageway trunk roads is not currently published. However, a broad analysis of the information contained in the Scottish Roads Traffic Database suggests that the average figure is around 11% for Scottish Trunk Single Carriageway Roads.
