oneway=reversible|alternating for highways

[naoliv]

With ​https://twitter.com/bhousel/status/948995008404729856 I guess that the usage of oneway=reversible|alternating¹ might increase.

¹ ​https://wiki.openstreetmap.org/wiki/Key:oneway#List_of_values

I am unsure if JOSM should also include them in the presets, but at least it should ignore the values when validating (so we won't see messages like Value 'alternating" for key 'oneway' not in presets)

Definition looks clear enough for me. Can we render these ways as iD does?

[Klumbumbus]

OK, but I think we need two way arrows too. Simply using our current oneway arrows would be a bit confusing.

[Don-vip]

That's what I meant: is JOSM already capable of displaying two arrows, or do we need to implement it first?

[Klumbumbus]

Replying to Don-vip:

is JOSM already capable of displaying two arrows?

I don't think so.

If you implement this maybe consider if it makes sense (and not too much work) to make them adjustable, so we could display oneway:bycycle=no arrows in a different style, similar to ​opencyclemap.

Which tag can I change to have vehicles drive on the left hand side?
