Helo everyone. I would like to pick up this month old discussion again and try to come to a conclussion. The situation so far: Problem: There are signposted hiking and biking routes, where the route itself goes only one way, because it's not way-marked in the opposite direction. How do we add that information in OSM? Current solution: oneway=yes. Not preferred by many on this list, as oneway should indicate a legal restriction. New solution: Some of you suggested alternative new tags, but we didn't come to a conclusion on this yet. What I have gathered from the various answers: - bidirectional=no - signed_oneway=yes - signed_direction=yes - designated_direction=forward|both|backward - signed=forward|backward|both|none Personally, I like signed_direction=yes. It's simple and avoids using the word oneway. Also, using the value forward|backward might not be necessary, as it's possible to deduce this from the order of ways in the relation.
This is a false assumption. You should never rely on ways in route relations to even be ordered at all. OSM route relations are often edited by less experienced or non-technical contributors with no idea about ordering at all and there are also lots of cases where you can't even order a route in a meaningfull way.
Any other views? Anybody against replacing oneway=yes with signed_direction=yes in the wiki pages of route=foot and route=hiking?
I happen to know the guy who came up with the oneway=cw/ccw tagging (https://wiki.openstreetmap.org/w/index.php?title=Tag:route%3Dhiking&oldid=1453921) and remember briefly discussing it with him (he mapped a ton of walking/hiking routes in the areas around the danish/german border).
I don't really have much of a problem with oneway=* on route relations (since the meaning is fairly obvious to me), but I'm not against replacing it (note that the inventors primary language isn't english) , but have to state that the cw/ccw values (I suggested clockwise/anticlockwise) are necessary, since there's really no other way to indicate which direction a circular route is better followed.
Do also note that clockwise/anticlockwise values can be usefull for human consumers, even though they may not be for data consumers.
