in the US, we've been trying to use unsigned_ref= for situations where
the road
has a designation but no signage. County routes in Westchester and
Onondaga Counties
in NY are examples of this. additionally, many of the highways in the
NYS parkway
system have public designations like "Taconic State Parkway" but they
also have
unsigned reference numbers in the state inventory, so ref=TSP combined with
unsigned_ref=<inventory number> is the way we've been going.
