I would like the help of the list to clarify the meaning of having a
"locked=yes" tag on a barrier node together with some allowed access tags.

The introduction to the "locked" tag wiki page
https://wiki.openstreetmap.org/wiki/Key:locked says:

access <https://wiki.openstreetmap.org/wiki/Key:access>=* is used to
> describe the legal permission to travel through a barrier but does not
> indicate in emergencies what the physical access is
>

Therefore, my understanding is that

   1. As far as non-emergency routing, the "locked" tag should be ignored.
   2. A "locked=no" tag indicates that a legal access restriction is not
   enforced by a lock and therefore could be overcome in case of an emergency.
   3. A "locked=yes" tag indicates that the legal access restriction is
   enforced by a lock and therefore cannot be overcome in case of an
   emergency.

The "How to map" description in the wiki page seems to assume a gate or a
barrier with a simple "access=no". It is not clear with respect to any
permitted access methods.

For example, barrier node with the following tags:

tag value
barrier gate
motor_vehicle no
locked yes
bicycle yes
foot yes

I think this tagging says:

   - There is a locked gate that blocks motor vehicles
   - There are no access restrictions for pedestrians and bikes

This is not the interpretation of other people, as seen in a discussion on
a GraphHopper routing issue

https://github.com/graphhopper/graphhopper/issues/2757#issuecomment-1434806229

There you could also find a picture of such a barrier.

Please help us resolve the differences
