[Talk-us] Separate relations for each direction of US & State highways.

[Peter Davies]

James,

I have a question about this, though it all sounds good to me in principle.
 Is your proposal just about the relations?  What would we do on the refs
of the ways?  For example, on I-394 in Minneapolis and western suburbs, a
mapper has left off US 12 because it is at least partly unsigned. So we
have way ref I 394 instead of I 394;US 12.  For my applications I'd prefer
it said I 394;US 12, because we need to track the overlaps (which we and
our 10 state DOT customers call double banding).  But if you also want to
suppress shields from maps in such areas, could we enter the way ref as I
394;US 12|unsigned  ?
