Modelling the give way (yield) is the way I'd approach it too. Though rather than a give way node very close to the junction node I'd use a relation containing both the junction node and the road giving way (i.e. way c and node D in Matt's original diagram) to describe it. I already do this with stop junctions (see http://wiki.openstreetmap.org/wiki/Proposed_features/Relation:type%3Dstop) and advanced stop lines (I've still got to document the latter on the wiki).

That (of course) may be a problem with the editor I'm using, but keeping it simple is always a good maxim. So I'd much prefer a giveway instruction (giveway=yes or giveway=-1) on the way that gives way, probably on a node near the junction, and inferring the direction from the way that the node is on. I lost the will to read when much the same issue was discussed with regard to stop signs, so I don't know what the conclusion was (if any). Richard
