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 ...).</DIV><DIV><BR></DIV><DIV>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.<BR>

I think because of the way OSM works that it's usually better to be<BR>
explicit. A road with "maxspeed=50" has a clear meaning. A road<BR>
without a maxspeed could mean that there is no limit, that the limit<BR>
is defined by some local rule, that it simply hasn't been mapped, etc<BR>
etc.<BR>
