The traffic flow rangesfor use in the assessment of new rural roads, as recommended in the Design Manualfor Roads and Bridges, are as follows: Location Carriageway Standard Opening Year Annual Average Daily Traffic Flow Minimum Maximum Mollinsburn to Auchenkilns junction D3M 25,000 67,000 Auchenkilns junction to Mollinsburn D2M Up to 41,000 It should be notedthat these opening year flows are only used as starting points for economic evaluationof new roads and are dependent on many physical characteristics of the road beingassessed, such as frequency and type of junctions.
