</span>This use of warning signs runs into the problem that data consumers<br>
don't have a good way of figuring out which signs go with which<br>
directions of which roads. Yes, the 90% solution is to say "the sign<br>
is associated with the road it is closest to, and the direction of<br>
travel corresponding to the side of the road it is on", but there are<br>
exceptions, both common and unusual.<br></blockquote><div><br></div><div>Node could be in a way.</div><div>Way has a direction</div><div>We can use forward and backward keys, and also side=right/left/both to orient the traffic_sign. </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

Probably the most common exception in the United States is "no<br>
passing" signs (a common pattern is to have the sign on *both* sides of<br>
the road, so that someone in the process of passing a large truck will<br>
still see it), and the second-most-common is advisory speed limit signs<br>
placed on the outside of the corresponding curve. Various<br>
clarification signs in close proximity to confusing intersections would<br>
have issues with "which road" rather than "which direction".<br></blockquote><div><br></div><div>If the node is in a specific way this sign belongs to that way </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
<br>
Warning signs are something that data consumers could certainly make<br>
use of, but we need some way of explicitly coding which direction of<br>
which road they apply to.<br></blockquote><div><br></div><div>Is not enough to belong to a specific way or to have it closest?</div><div><br></div><div>Salut i senyals de trànsit (Good health and traffic signs</div><div>yopaseopor</div><div><br></div><div> </div><div><br></div></div><br></div></div><div id="DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2"><br> <table style="border-top:1px solid #d3d4de">
