[Tagging] Lane geometry in OSM

[Marc Gemis]

while this might work, why would you try to replace an established
tagging system ?
The tagging system turn:lanes:xxx is  supported by several data
consumers (OsmAnd, maps.me, MagicEarth and probably others).
In many countries people worked on tagging all roads with this system
after a project set up by the German community.

This could be used to extent the width tagging for transition lane (where one lane split to two (or conversely). There are already a lot of possibility to tag detailed lanes, but we could indeed add the width in it !
