This report is a re-publication of the 2nd report in a series of reports setting out the levels of congestion on 44 monitored sections of the trunk road network in Scotland in 2004. Since the earlier publication in 2007, of the Congestion Data Report 2004, we have revised the original indicators used to ensure the information provided in this series of reports remains useful. In light of these changes we are re-publishing this 2nd report in the series.
