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 the transfer. 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. > Regarding travel details of ferry/rail/bus sections within bicycle routes: > This information, if available, should go on the the ferry/rail/bus route > relations, as these means of transport are not exclusive to the bike route, > at least in most cases, and therefore should have their own relations > independently of bicycle travel. > > In more general terms, this intermodal transport problem is a big black > hole in OSM in general.

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! > On Mon, 31 Aug 2020 at 09:53, Peter Elderson <pelder...@gmail.com> wrote: > >> Jo: >> >>> I added that it's not needed for ferries in the proposal on the wiki. >>> It's alright if we have more than 1 way to do it and leave it up to the >>> mapper to decide whether to map as a single route relation or split them >>> and use a superroute relation. >>> >> >> Wouldn't this apply to other transfer/transport sections as well? >> >> >>> If I start doing a bicycle tour, I want to know in advance if I'll be >>> able to cycle the whole stretch, or if there will be waiting time for other >>> means of transportation.
