Ideally you would be explicit, but personally I don't tag every single way with a maxspeed (or lanes or smoothness or surface or width ...). As for routing, an assumption that highway=residential is 30 unless it says otherwise and everything else is 60 unless it says otherwise (or is a motorway/dual carriageway) would probably work ok.

I think because of the way OSM works that it's usually better to be explicit. A road with "maxspeed=50" has a clear meaning. A road without a maxspeed could mean that there is no limit, that the limit is defined by some local rule, that it simply hasn't been mapped, etc etc. Steve _______________________________________________ newbies mailing list [email protected] http://lists.openstreetmap.org/listinfo/newbies -- _______________________________________________ Surf the Web in a faster, safer and easier way: Download Opera 9 at http://www.opera.com Powered by Outblaze
