What its estimate is of the number of vehicle kilometres travelled on Scotland's roads, broken down by classification of "built-up" roads a…

The Department of the Environment, Transport and the Regions (DETR) produces estimates of the total numbers of vehicle kilometres travelled on Scotland's major roads (motorways and A roads). These figures appear in Chapter 6 of Scottish Transport Statistics no. 18 / 1999 edition, copies of which are available in the Scottish Parliament Information Centre. The last four rows of Table 6.1 give the DETR estimates for the past ten years for all major roads, for Motorways, for "built-up" A roads (those for which the speed limit is no more than 40 mph), and for "non built-up" A roads (those for which the speed limit is over 40 mph).DETR has recently published provisional estimates of the volume of motor vehicle traffic on minor roads (B, C and unclassified roads) in Scotland in 1998: 5,700 million vehicle kilometres on non-built up roads and 11,300 million vehicle kilometres on built up roads. Figures cannot be provided for earlier years because, as Scottish Transport Statistics explains, the sample which collects the data from which the minor road traffic estimates are produced was designed only to be the basis of estimates for Great Britain as a whole: prior to 1998, the Scottish part of the sample could not provide reliable estimates of minor road traffic for Scotland. From 1998, DETR has increased the size and improved the design of the sample, and Scottish estimates can now be published: they will appear in future editions of Scottish Transport Statistics.
