[Tagging] Emergency Access

[Peter Wendorff]

Hi Andreas,
IMHO
- access=emergency is a basic access restriction, which states that only
emergency vehicles are allowed here (unless otherwise specified).
- emergency=yes is such an "otherwise specification" where the main
access rule is different, it's simply another way to define the same.
- service=emergency_access sounds more as a subtag for highway=service
and my interpretation would assume this is a service way with the
primary purpose to allow emergency vehicles to access another facility
(be it a building, highway or anything else).

service=emergency_access might allow usage by others, but usually
forbids e.g. parking (if it's an access road to a building)

access=emergency should usually be implicit on any other access and
therefore might usually refer to ways where only emergency vehicles are
allowed (although e.g. highway maintenance vehicles and similar stuff
might be allowed to share these ways).

regards
Peter
