[OSM-talk] Clarifying and representing road markings at junctions

[Gregory Williams]

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).

You could record it as a type of turn-restriction relation, but I have a
prejudice against those, having copied them down a bus route for quite a way
until I realised I'd picked up a stray. 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).
