Think about oneway tag. http://wiki.openstreetmap.org/wiki/OSM_tags_for_routing That is a property of a way. So as a routing app I just would like to examine this tag, and forget the relations restrictions: http://wiki.openstreetmap.org/wiki/Relation:restriction Because it is a redundancy - if the oneway tag used properly the routing app can determine whether you can turn right in an intersection or not. In other words - if someone missed defining the road signs at intersections (eg, restriction=no_left_turn) then this does not mean that you can turn left.
So I would prefer to create such tags for priority cases - which can be assigned to ways Thanks, Balazs On Tue, Nov 5, 2013 at 11:59 AM, Steve Doerr <[email protected]>wrote: > My understanding is that a give_way node on a way should be placed such > that it is closer to the relevant intersection than it is to any other > intersection of that way.
