I'm not entirely clear what you mean by those terms as you're
American.
That's okay; that makes two of us ;-).
The image in the wiki for parking lanes matches
what I expect of it. As in this situation near me:
https://goo.gl/maps/WUZKmhQTDSRsgnDx7 on the right
of the road are double yellow lines, which mean "no parking
or waiting at any time" (but there are exceptions) and on
the left is a single yellow line which means "parking and
waiting permitted some of the time" (though there are
exceptions and provisions and it gets complicated). The
left is a parking lane, as I understand it. There are no
parking spaces marked.
AFAIK there is nothing exactly like that in the US. People do park on
streets (note 5th, 4th and 3rd Avenues, as previously mentioned), and
there is sometimes signage regulating this.
Actually, this might answer one of my prior questions; is =marked
supposed to be used for stretches that alternate between parking allowed
and parking forbidden?
BTW, this is what NYC apparently considers a "parking lane":

Based on this discussion, it seems to me that that is *not* a "parking
lane" as OSM uses it.
That said, I think the US definition may be "a lane which is for
parking, rather than through traffic, and which may be intermittently
present" (e.g. the above video). However, I am much *less* convinced
that it is useful to model them that way, at least in the current state
of things.
Well, there's an easy solution to that; map the spaces, also ;-)
Yeah, but the spaces don't render. Oh wow! I just checked one of your
later examples and parking spaces now render. I'd given up on hoping that
they would render. Doesn't fix the example I'm thinking of, though - it's
clearly a pregnant bulge that is for parking, but no spaces are marked.
Ah, yes, that would be an issue. Not sure what was with the not
rendering, unless you happened to look at it soon enough after I
uploaded the changes. There does seem to be a variable delay between the
database changing and the rendered tiles being regenerated.
it's normal for a parking lot area to include at least parts of the
aisles.
In one sense it's correct. At a level of highway modelling we don't do and
may never do. In terms of what gets rendered (where the renderer draws
roads on a layer above parking lots), it's perfectly comprehensible. Since
we don't have a better way of representing what's there, I ignored the
objection.
Agreed; if the road was mapped also as an area, it would make sense.
...and to be honest, another argument for modeling as lots is that the
parking_lane tagging is rather more obtuse...
There is that. Which is why I tend not to bother with it. Especially as it
means surveying and finding out the restrictions on times.
Meh, I'm happy to omit the restrictions :-).
