Identify "on/off ramp" connections on cycleways and multi-use paths that
have a "bicycle superhighway" configuration.

I've stopped bothering with it because it's badly supported by consumers
and is a real pain in the tail to maintain.  I don't think roles other than
"forward" and "backward" are commonly used for child relations, though
cardinal directions appear in super-relations where the children are
one-relation-per-direction, pretty much a necessity for RCN and NCN routes
in the US where a state line terminates the route on a dual carriageway.
