To add to confusion, different state agencies may use different
numbers (perhaps a toll road without a signed number is given one
number by the DOT and another by the toll agency). Or take those
states where the route numbers are defined legislatively. Or Oregon,
where there are highway numbers (unsigned) and route numbers (normally
signed) - but some route numbers have been officially designated but
not signed, and may differ from the highway number.

I think there are enough possibilities that no single method will
work. I've used FDOT_ref for hidden state road numbers in Florida, and
it's enough for Florida's system. Other states may need more. Or
unsigned_ref may be sufficient in many places.
