“stop:forward=yes” & “stop:backward=yes” seem like they are putting a value in the key as the stuff to the right of the equals may never be anything other than “yes”. On the “lanes:forward” and “lanes:backward” keys at least the values carry variable values. There is already a “traffic_signals:direction=forward | backward” usage. “stop:direction= forward | backward” and “give_way=forward | backward” would fit that schema too. > On Mar 22, 2017, at 4:57 PM, Martin Koppenhoefer <dieterdre...@gmail.com> > wrote: > > generally it is unsafe to rely on a "direction" like forward or backward as > tag on a node.

Although one might suggest that it is a theoretical situation as the definition of the stop tag [1] indicates that if on the node connecting multiple then it is a all way stop. And if not on an intersection node then it should be placed at the stop line. [2] I don’t think we are likely to have a stop line in the middle of an intersection. :) [1] https://wiki.openstreetmap.org/wiki/Tag:highway%3Dstop#All-way_stop [2] https://wiki.openstreetmap.org/wiki/Tag:highway%3Dstop#Tagging_minor_road_stops
