I think this is a sensible scheme and can go either into 'maxspeed' (in which case client applications will need a lookup table of what GB:motorway means) or else into 'maxspeed:sign' (in which case the 'maxspeed' tag contains the literal mph value, and will need automated retagging in case the national limit changes). However, one flaw is that the speed limit sign is not for 'dual carriageway limit applies' but rather 'national speed limit applies'. So we still would not be tagging exactly what appears on the sign, but adding some additional interpretation. I think that is fair enough, but those who hold to a strict on-the-ground principle may disagree. (I don't currently map speed limits unless they are very low, like 5mph, so my view should not carry as much weight as that of mappers who actively maintain the highway network, or those who use the speed limit data.) -- Ed Avis <[email protected]> _______________________________________________ Talk-GB mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk-gb
