What value should we use for source:maxspeed=* in built-up areas when<br>
there's no signage or road markings, just street lights?<span><font color="#888888"><a href="http://lists.openstreetmap.org/listinfo/talk-gb" target="_blank"></a><br></font></span></blockquote><div><br>There was bit of discussion on this about a year ago.<br>
While some guidance may strongly indicate (mislead?) that lightng+urban area = 30mph this is not the case. These roads are 'National Speed Limit - Restricted Roads', where the presence of street lighting enforces and reminds that the road is a Restricted Road. As Restricted Roads do not necessarily occur in 'build up areas' I think using built-up_area would be misleading. The word 'restricted' may not be commonly used, but it has the effect of making people think about what they're adding.<br>
<br>More importantly taginfo shows source:maxspeed=UK:restricted_road is clearly the common way of tagging uk restricted roads.<br><a href="http://taginfo.openstreetmap.org/search?q=source%3Amaxspeed%3Duk">http://taginfo.openstreetmap.org/search?q=source%3Amaxspeed%3Duk</a><br>
<br>I didn't respond the original emails a year ago, but as a result I did start adding speed limits. Quickly realised how utterly confusing UK/GB speed limits are and wrote down a bundle of notes mainly aimed at trying to work out speed limits on badly signed roundabouts along NSL roads. Lost original notes but a lot was remembered and I've added them to a personal 'uk speed limit notes page'. I think it sums up GB/UK speed limits, and I've cleaned it up a lot today.<br>

The intended result is the same and I have a preference for GB because it's 'official', but once again taginfo shows that UK is the common way of indicating the speed limit is British version.<br>

I can't support changing to GB unless it involves changing all the UK maxspeeds to GB maxspeeds. Having two versions is confusing and unless this can happen I'd rather stick with UK.<br><br>Cheers,<br><br>Jason<br>
