I may be missing the point on all of this, but: Why are we doing this? In OSM we optimise for the mapper, not the data consumer. That means we tag exceptions, not majorities. So if you have highway=motorway, the consumer can assume the national speed limit applies, which is 70mph; no need for a maxspeed or maxspeed:type tag. If you have highway=trunk (or anything down to unclassified), assume the national speed limit applies, which is currently 60mph if it's a single carriageway, 70mph if it's a dual[1]. And so on. Where this isn't true, you put a maxspeed tag on. This works for pretty much everything from 30mph on B roads through villages to 50mph on rural A roads to 70mph on the A55 Special Road. No need for a maxspeed:type tag at all. Have I missed something blindingly obvious? cheers Richard [1] Perhaps the only difficulty is that there's currently no trivial way to identify what's a dual carriageway and what isn't, short of doing clever geometry stuff. But that's easy to fix: either a relation (spit) or preferably something simple like dual_carriageway=yes. -- View this message in context: http://gis.638310.n2.nabble.com/Maxspeed-tagging-for-the-UK-tp6245995p6272282.html Sent from the Great Britain mailing list archive at Nabble.com. _______________________________________________ Talk-GB mailing list Talk-GB@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-gb
