But that shouldn't be too much of a surprise. A trunk road would be expected to have a high traffic volume precisely because it's important to the network. A sensible administration will likely give it particular attention when budgeting money for road improvements. To say that "trunk == dual carriageway" would be to put the cart before the horse. To say that "the presence of a dual carriageway on an interurban route is an indicator that the road may be important enough to be considered a trunk," should be relatively noncontroversial.</div><div><br></div><div>Of course, some dual-carriageways don't exist to link centers of population. Those are probably primary roads, possibly primary expressways. (I don't actually understand what constitutes an 'expressway' - that appears to be a question where, if there are two mappers, there are three opinions.) And some dual carriageways are best described as roads for which some political constituency has aspirations that they may become trunks.</div></div><div><br></div>-- <br><div dir="ltr" class="gmail_signature">73 de ke9tv/2, Kevin</div></div>
