Hi there.<br>
Following this topic, I would like to extend the discussion to the
mail list, because I think this is an important issue that should
have a broad solution.<br>

<br>
Several months ago, I stumbled upon a problem which I found no
solution to. At the time, I searched for help in the Telegram
channel and someone gave me a solution that I've been using since
then.<br>
Meanwhile, another mapper contacted me in private and told me about
another kind of solution to this problem.<br>
I would like to know if these are both valid and/or which one is
more useful for routing.<br>
<br>
I'm showing here illustrations of the problem and the two solutions
given.<br>
<br>
<br>
<b>Problem #1:</b><br>
<a class="moz-txt-link-freetext" href="https://i.imgur.com/8MiiKFH.png">https://i.imgur.com/8MiiKFH.png</a><br>
<br>
The selected way has a STOP at the end for those who turn left and a
give way sign for those who turn right.<br>
The "problem" is: how to map those two signs correctly and make them
useful for routing software?<br>
<br>
<b>Problem #2:</b><br>
<a class="moz-txt-link-freetext" href="https://i.imgur.com/cLFRtLG.png">https://i.imgur.com/cLFRtLG.png</a><br>
<br>
There are no painted islands and no physical divisions. The middle
lane as a STOP sign to turn left.<br>
<p>If you have<br>
lanes=3;<br>
lanes:forward=1;<br>
lanes:backward=2;<br>
turn:lanes:backward=left|through </p>
<p>how do you indicate that there's a STOP on one of them?</p>
<br>
<br>
<br>
<b>Solution #1:</b><br>
<a class="moz-txt-link-freetext" href="https://i.imgur.com/HDmvZiB.png">https://i.imgur.com/HDmvZiB.png</a><br>
<br>
Use both traffic signs on the way and create one enforcement
relation for each of them. A "from" enforcement on the STOP and a
"to" on the left segment of "Rua Paulo VI" and a "from" enforcement
on the give way and a "to" on the right segment of "Rua Paulo VI".<br>
<br>
<br>
<b>Solution #2:</b><br>
Just use the following tags:<br>
highway=secondary<br>
lanes=2<br>
oneway=yes<br>
name=Rua da Quinta<br>
ref=EN 350<br>
surface=asphalt<br>
traffic_sign:lanes=stop|give_way<br>
turn:lanes:forward=left|right<br>
<br>
I never used traffic_sign:lanes tag, but it seems legit, although
Taginfo only shows 20 uses for this:<br>

<br>
<br>
Any considerations would be much appreciated.<br>
<br>
Regards.<br>
