<div dir="ltr"><div>Yes, I know that junction=yes works fine for simple crossroads. My question is: How should we map complex junctions like <a href="http://www.openstreetmap.org/node/2351057522#map=19/5.34399/-4.00300">http://www.openstreetmap.org/node/2351057522#map=19/5.34399/-4.00300</a> Using just an unconnected node like in this example (even after removing the wrong place=hamlet tag) maybe is difficult for turn-to-turn navigation software. So, how can we solve this?<br>

<div dir="ltr">Current situation:<br>We have the tags highway=traffic_signals (for traffic signals on road junctions or at straight roads – typical for Japan) and junction=yes (for road junctions with or without traffic signals – typical for Ivory Coast) in use at OSM. Both tags are almost exclusively used on nodes. They can be used together with name=*. This works quite well for simple crossroads (example: <a href="http://wiki.openstreetmap.org/wiki/File:Junction_yes_example_1.png" target="_blank">http://wiki.openstreetmap.org/wiki/File:Junction_yes_example_1.png</a>)<br>
<br>Shortcomings of the current situation:<br>It isn’t defined how to tag more complex cases. </div></blockquote></div></div><br><br><br></div><div class="gmail_extra">maybe the junction key can be used more universally (with different values), we are already using it also with junction=roundabout, only that it could be disputed that junction=roundabout is covering the whole junctions (the entries and exits you often have to a roundabout could be seen as part of the junction for instance). More in-use values can be found here: <a href="http://taginfo.openstreetmap.org/keys/junction#values" target="_blank">http://taginfo.openstreetmap.org/keys/junction#values</a><br>
</div><div class="gmail_extra">Some of them maybe aren't junctions (what kind of junction is "approach"?), others are diverging from our standard mantra (no abbreviations), like "spui" or "ddi" and might merit retagging?<br>
