This sounds reasonable. Round here (Oxford), there are three types of on-the-ground signs for the local cycle network: Numbered signs that appear to meet the "Traffic Signs Regulations and General Directions 2002" (TSRGD 2002) - I think these have only been used where the local network follows a route also on the national network, so they're all double-labeled, EG: http://cycle.st/p34892 Numbered "Oxford Cycle Network" signs, EG: http://cycle.st/p34893 Unnumbered TSRGD 2002 signs, with just the route's destination on them, EG: http://cycle.st/p34890 Obviously, the first two are enough to justify lcn_ref= and in general the last gets at least lcn=yes. However, knowing the numbering scheme of the network it's possible to infer the lcn_ref even when it's not on the sign: Route 1 (which numbered signposts) follows NCN 51 roughly North-South to the city centre, then there are 8 more spokes, numbered clockwise, and finally 10 is the ring-road cyclepath. This used to be displayed as a poster on information boards around the city, and was the source of of the numbering when I've used lcn_ref= for unnumbered routes in the past. I don't think the poster is on display any more, but that doesn't mean it's bad data! > - Cycle networks that are not significantly verifiable on the > ground, but are proposed for official adoption and are under active > discussion with the transport authority, are tagged as lcn=proposed. I'm much more nervous about this - OSM is not the place for planning data. I think =proposed should only be used in the case SomeoneElse mentions. That is, the exact route has been finalised but the signs on-the-ground have not yet been installed. cheers Stephen _______________________________________________ Talk-GB mailing list Talk-GB@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-gb
