Perhaps the speed limit tagging could help? I guess it is normally fine
to cross in a 30mph limit, but not in a 60mph limit without a dedicated
crossing.

There are proposals for tagging the crossings.

It is interesting that the lane proposal here
http://wiki.openstreetmap.org/index.php/Relations/Proposed/Lane
doesn't have anything about whether the road is safe to cross or
barriers in the middle...
