I also thought that it would contradict the other tags. But, the wiki page http://wiki.openstreetmap.org/wiki/Tag:access%3Ddesignated seems to pretty much say we're both wrong on that score:
"The value *designated* is not meant to imply that OpenStreetMap access <http://wiki.openstreetmap.org/wiki/Key:access>=* permissions have been automatically 'designated' *only* to that transport mode! If an element is meant *only* to be used by specific designated transport methods (overriding whatever defaults may exist for that way), use access <http://wiki.openstreetmap.org/wiki/Key:access>=no <http://wiki.openstreetmap.org/wiki/Tag:access%3Dno> in addition of the * <http://wiki.openstreetmap.org/wiki/Key:*>=designated value." I say "seems to," which is why I wanted to ask for clarification. With respect to the HOV lanes, it matters greatly, because there are certain interstate exits that are HOV-only which a router shouldn't choose those to get somewhere if you're not carrying multiple passengers in your car (which is pretty much the default in the U.S.). --jack On Tue, Nov 15, 2016 at 6:13 PM, Elliott Plack <[email protected]> wrote: > Jack, > > Good question.
