I think there are four types of alleys
- rear access to properties, a sort of shared service road. Tagged
service=alley
. New York example - narrow streets, but still wide enough for cars, provides access to front of properties. Controversial. Tagged
highway=service service=alley
or=residential
etc. withwidth=
. Rome example - narrow streets, too narrow for cars, but legal for motorcycles etc. Tagged either
highway=service service=alley
(Italy example) orhighway=path motorcycle=yes
(Bangkok example) - footways and steps. Edinburgh example
I think the new tag, highway=alleyway
or similar, would be for (2) and (3), correct? Leaving service=alley
for (1), and leaving (4) alone.
Or would it just be for (3)?
