to use key:destination on motorways and similar roads (primary WITH<br>
primary_junction), because there you have normally no crossroads, but<br>
only “y junctions” on oneways. So for motorways it is more likely that<br>
there is only one version of the content of the signposts. But at<br>
normal crossroads, it may be more likely that the signpost content for<br>
one of the leaving ways is different (different content depending of<br>
the road from which you are coming).<br>
<br>
However, that’s just raw guess about the original intention. Also<br>
unsure if all these assumtions are correct (on the ground).<br>

</span>+1. Key:destination for the simple cases the the relation for the<br>
complex cases seems fine for me.<br>

PS: In the wiki, Key:destination is used for “signposts or ground<br>
writing”, but Relation:destination_sign only for signposts. I would<br>
extend Relation:destination_sign also to ground writings. And in<br>
general, I think it would be a good idea to harmonize the allowed tags<br>
(key:distance, key:time) between key:destination and<br>
relation:destination_sign.<br>
<br>
PPS: As far as I understand, the key:destination is used on OSM ways<br>
_after_ a signpost/groundwriting. If this is correct, the examples<br>
with the yellow and white signposts on the wiki page are confusing<br>
(tagging a motorway_link makes no sense here), and I would recommand<br>
to remove these three examples.<br>
