I am creating hiking routes for some of the trails in my area. Several of these trails include an "entry" way from the trailhead to a loop. After completing the loop, one walks back to the trailhead along the "entry" way in the opposite direction. I am not sure about the correct way to represent this in the route. It seems like I should add the "entry" way twice, once at the beginning of the route and once at the end. JSOM gives me an warning when adding it twice, but lets me. Second time, the hike in in the opposite direction of the way, and seems like it would be appropriate to "reverse" the way for this (to keep the elevation plots/navigation correct). I tried applying the role "backward" and "reverse", but JSOM gives warnings for both. And "backward" appears to be defined to mean ONLY in the direction opposite the way (but I want to use the way in both directions). https://wiki.openstreetmap.org/wiki/Relation:route Here is a route where I used the role "backward" for the second pass along the "entry" way Here is a route where I reused the "entry" way without a role: Guidance for the best practice? (and any other suggestions for these routes) Thanks |

JOSM gives a prompt regardless when you add a member twice. This is about editing. It's less of a "warning" as validator ones.
I agree with Kovoschiz, I would see this warning as JOSM prompting you to check that you really did intend to add the member twice, rather than suggesting it is an error.
As far as I am aware, it is fine to add ways twice to hiking routes if that is how you would walk the route in reality. The "meaning" of the double appearance is implied by the order of the members. Here is a slightly different example where I mapped a short trail that requires one section in the middle of the route to be walked twice to reach a viewpoint and return: https://hiking.waymarkedtrails.org/#route?id=7157490&map=18!36.725!-4.4078 . It seems to work OK, e.g. waymarkedtrails correctly works out the mapped length counting this section twice.
If you feel the entry way is more like a way of getting to the "real" route rather than fully part of the route, then you could consider using the approach role as InsertUser mentioned. There is more on roles here: https://wiki.openstreetmap.org/wiki/Proposed_features/Recreational_route_relation_roles . These roles are relatively new. Possibly if I was mapping my above example now I would consider the "excursion" role for the repeated section.
