There *should* always be signage indicating a change in maxspeed from something else to 30 mph. The street lights merely act as repeaters, since normally repeaters are required every so many yards for a non-NSL limit. The presence of street lights does *not* mean 30 mph (just need to look at any lit motorway for evidence of this). I have found anomalies, though. In fact, I happen to live on a road which is not signed correctly. It joins a 40 mph road, but there is no indication of change of speed limit. I have informed my local council about this but never heard anything back. I think really the only thing we can do in such situations is use common sense. So source:maxspeed=common_sense? Alternatively, you could ask the local council which should know the real limits. -- Borbus. ___ Talk-GB mailing list Talk-GB@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-gb
[Talk-GB] NSL in built-up areas: what source:maxspeed to use?
What value should we use for source:maxspeed=* in built-up areas when there's no signage or road markings, just street lights? Specifically the concept expressed in http://en.wikipedia.org/wiki/Built-up_area_%28Highway_Code%29 Searching taginfo suggests: * "source:maxspeed=GB:built-up_area" (+ var: "built_up-area"...) From 1385 uses without GB: or UK: prefix for the somewhat uncommon maxspeed:default=*, but we could use it for the more usual key too. Source: http://taginfo.openstreetmap.org/search?q=maxspeed%3Dbuilt * "source:maxspeed=GB:restricted_road" From 394 uses of similar-looking things in taginfo, most of which are UK: prefixed. Src: http://taginfo.openstreetmap.org/search?q=maxspeed%3Drestricted Any other possibilities? I think I prefer the former even if using both a hyphen and an underscore make it ugly and error-prone. It's the more common term in everyday parlance, and we're not doing designations here. There don't seem to be any relevant matches for "lit" or "light". I'm planning on making a presets bundle for them, so values would need would need to fit alongside GB:motorway, GB:nsl_dual, GB:nsl_single. -- Andrew Chadwick ___ Talk-GB mailing list Talk-GB@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-gb
