If a way or a chain of ways in a route relation has no
forward/backward role, you can assign it a transfer/transport role.Easy
for e.g. ferries operating in both directions.
If the bicycle has split directions and transfer/transport is also
different for the travel directions, I think a route_master relation is
needed for the transfer. The superroute will have as members: the bicycle
relation up to the transport; the routemaster relation with the
transfer role, and the section of the bicycle route at the other side of
I think for most bicycle routes this kind of transfer will have a shared
way or shared point near the transport. So I think this will not happen
very often.But if it does, tagging can be done as described above without
ever having to combine roles. Processing is another matter, though.

The development is instant point-to-point routing over different
networks and transport modes. Route relations pre-combine elements to
form a fixed route for a particular purpose, e.g. a theme or named trail
to be followed exactly. I don't think roles in fixed route relations will
solve the instant routing challenge!
