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. More importantly taginfo shows source:maxspeed=UK:restricted_road is clearly the common way of tagging uk restricted roads. http://taginfo.openstreetmap.org/search?q=source%3Amaxspeed%3Duk 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. http://wiki.openstreetmap.org/wiki/User:Jamicu/UK_Speed_Limits Second issue is the change in the wiki to suggest GB instead of UK. 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. http://taginfo.openstreetmap.org/search?q=source%3Amaxspeed%3Duk http://taginfo.openstreetmap.org/search?q=source%3Amaxspeed%3Dgb 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. Cheers, Jason
