In my city, we have HOV (High-occupancy vehicle) lanes that you can only merge in and out of in certain sections. I would like to map this, but I can't find any way to map merging restrictions. There is no physical barrier, only paint/signs, so I'm quite certain that it should be mapped as a single way.

There are 5 total lanes, 1 HOV (2+) and 4 regular. I've mapped this as:

  • highway=motorway
  • lanes=5
  • motor_vehicle:lanes=no||||
  • hov=designated||||
  • hov:minimum=2

How do I map the no merging sections? How do I map the sections where you are allowed to merge?
Bonus: there are signs that tell you to exit the HOV lane to make specific exits. Can I tag those as well?

I figured it out. There's a proposed key change:lanes that's pretty well used.
https://wiki.openstreetmap.org/wiki/Proposed_features/change
So additionally I'd tag the restricted sections as:
change:lanes=no|not_left|yes|yes|yes

and the non-restricted sections as:
change:lanes=yes|yes|yes|yes|eys
