If the route as a whole is a roundtrip, then exactly that point.
Let’s assume the route has stops: A1 B C D E A2 A1 and A2 may be exactly the same point or close to each other, but that doesn’t matter, because for a roundtrip route, I would expect the vehicle to visits: A1 B C D E A2 A1 (if different from A2) B C D E A2 … And so on, until end of service (of the vehicle) If I get on at B, and it’s a roundtrip route, I would expect to be able to later get off at B again.

You can have routes where the start and stop are the same location, but this is not true (as the vehicle always goes on to serve another route after arriving at the last stop).

Explanations just say <https://wiki.openstreetmap.org/wiki/Key:roundtrip> roundtrip=yes/no (optional) Use roundtrip=no to indicate that a route goes from A to B. Use roundtrip=yes to indicate that the start and finish of the route are at the same location (circular route). It seems rather pointless to tag an obvious a-b route with roundtrip=no, or an abvious roundtrip with roundtrip=yes. Why would you tag an a-b route as roundtrip=yes, or a closed route as roundtrip=no? The only use case I can imagine is when a roundtrip has one ore more access ways which are included in the route relation. But even then, what is the purpose? Allowing apps to select only "official" roundtrips? Is that a valid reason for tagging? -- Peter Elderson _______________________________________________ Tagging mailing list Tagging@openstreetmap.org <mailto:Tagging@openstreetmap.org> https://lists.openstreetmap.org/listinfo/tagging -- Vr gr Peter Elderson
