Till now I solved this by defining one stop in the loop as terminus.
This lines then take different routes for each direction. Therefore I
found the solution with single-direction route relations quite
suitable. I don't know if this is the best solution for openstreetmap
but I defenately think that there ist missing something in the
established scheme.
I agree, I do it equal.
The forward or backward role of a way in the relation is in my opinion
useless, because it is not clear if it refers to the direction of the
way or the route. Currently it is used in both senses.
I agree to this too.
I think what we're edging towards is that expressing a tram stop as a
single node isn't really enough. I think the open question is how tram
stop pole nodes should be tagged, whether that affects
highway=bus_stop, and how you deal with joint bus and tram stops.
When I first discovered the oxomoa-scheme I thougt that it's quite a
good idea to use the new tag "public_transport" because what's the
difference between bus and tram stops - there are enough stops used
by both means of transport. After following this discussion here I'm
not so shure any more because world wide there are already mapped about
660000 bus stops as highway=bus_stop and it's senseless to retag all
this stops. On the contrary there are also already mapped about 57000
objects as public_transport=* (23000 nodes as stop_position and 22000
nodes and ways as platform) which of course is much less but also too
many to retag all these.
Because highway=bus_stop (pole) and railway=tram_stop/halt (stop
position) have different meanings the current schema is stamped with an
inconsistency. Resolving this inconsistency would require a redefinition
of at least one of these tags. As you have written: This does not make
sense.
I don't know which tags are best to be used at the moment but I'm really
interested in a broadly accepted guideline for a more unified taging in
the future.
The longer I think about it, I think it would make sense to use new and
clearly defined tags. But the well known tags highway=bus_stop and
railway=tram_stop should not lose the meaning/value. In the new schema
it should be defined how they are interpreted. For example: node on the
way => stop position; node beside the way => pole/platform. So we do not
loose information and the already invested work does not lose the value.
Actually in my proposal this is missing.
