Add layby to parking field

[boothym]

https://wiki.openstreetmap.org/wiki/Tag:parking%3Dlayby

Would be useful to have this value added to the dropdown as it's a useful refinement to a parking object. This is actually used more often than some of the values already included in the parking tag.

Lines 6 to 15 in 278b044

Sorry for being late with feedback here after @tyrasd just pushed the requested change.

I just wanted to make sure we have this value explained properly. Or, in case the explanation leaves room for misunderstanding, maybe we should scope this value to the UK where the Wiki says it is most common?

Mind, that we cannot really look just at the usage numbers, because the tag was (miss)used in the past (more below).

Background: I remember a recent proposal and discussion that tried to untangle the lay(_|-)by values. Mind, that this values here for key parking (not key parking:lane) is fine; this is just to document the previous and recent discussion and make sure mappers don't misunderstand the value.

• https://wiki.openstreetmap.org/w/index.php?oldid=2066642#Relation_to_other_parking.3D.2A_values tries to untangle a bit of history, concluding in deprecating the value for the parking:lane schema
• https://wiki.openstreetmap.org/wiki/Key:parking:lane#Parking_position deprecates the tag for parking:lane and also stresses the rest area character of parking=layby
• https://wiki.openstreetmap.org/wiki/Tag:amenity%3Dparking explains it with "take a break"

  A minimal parking facility alongside a major road where motorists can take a break en-route to their destination.

• https://wiki.openstreetmap.org/wiki/Tag:parking%3Dlayby tries to cleanup old tagging with the "when not to use" headline

Yes, thanks for adding it, but you've used the word "turnout" which nobody British will understand, although I assume it can be translated to en-GB?

The only place I've came across that word is in relation to the tagging of passing places in OSM: https://wiki.openstreetmap.org/wiki/Tag:highway%3Dpassing_place

If you're not familiar, an example of a layby can be found here: https://www.mapillary.com/app/?pKey=1558477194356640

If it where not for the [P] sign I would for sure map this as a highway=passing_place.

Looking at the map, I wonder if we should start by scoping the value to GB and wait for the Finish(?) community to request it as well https://taginfo.openstreetmap.org/tags/parking=layby#map.

If it was a narrow road then yes, but it's a two lane road though so you don't need a passing place 😉

"Turnout" which I don't know as a term

I went with the term Wikipedia mentions on https://en.wikipedia.org/wiki/Rest_area#Lay-bys: ‘Equivalent terms in the United States are "turnout" or "pullout".’

I also thought about labeling it as rest area, but I think that could be confusing in case of larger rest areas: “For larger rest-areas separated from the main road with its own service roads and other facilities, consider […] map the parking facilities there with parking=surface […]”

"turnout" which nobody British will understand, although I assume it can be translated to en-GB?

yes, it can be translated on transifex

Unfortunately, there is no elegant way to limit individual values of a combo field to certain regions. The alternative would be to duplicate the whole field, which would work, but is not ideal.

FWIW, I have personally actually encountered such "layby" parkings somewhat frequently on rural roads in Germany, Austria and (northern) Italy. They are just basically (still) mostly classified using parking=surface; probably because of the relative newness of the layby tag value and the lack of support in map editors?!

[boothym]

In general I suppose all parking is "surface" unless in a multi-storey or underground, but we have better and more refined tags that can be used for laybys and on street parking etc.

As for the translation - is there an en-ie translation as I think lay-by is used in Ireland as well? If not what about using something like "Lay-by / Turnout" to cover both cases without the need for translation?

As for the translation - is there an en-ie translation

As far as I can see, there is currently no dedicated en-ie translation active on transifex for the iD editor project (which includes also the presets. It could be added if you like (and if the Irish OSM community agrees).

I've also renamed the string to Turnout / Lay-By in 969421d for now.

Oh, I missed this discussion before posting 969421d#r64054862. “Lay-by” is so unknown and odd-sounding in American English that I’m sure it’ll cause any American English speaker who knows what “turnout” means to second-guess themselves.

Instead of overloading the American English localization with terms from around the world, why not create an en-IE localization and invite the Irish community to help override Americanisms with local vocabulary? It should just be a click or two for someone with project owner access in Transifex. I’m sure “turnout” isn’t the only thing that Irish English speakers would find confusing or off-putting. (As far as I know, its spelling is closer to British English anyways.)

[tyrasd]

Hey. There were a few different reasons behind me adding the term "lay-by" in this label:

• I wanted to wait for a confirmation of the Irish community if they actually want to maintain a translation.
• The regular en locale also needs to work for people who have set up the generic en in their OS/browser (see also #288 (comment)). This could be everywhere on the planet.
• The default en locale is also the basis for translators, so being a little over-specific helps to avoid translation errors.

I see now that my solution is not optimal for Americans. Apologies for that. I have an idea which could be a solution which works for everyone: Why not just add a dedicated en-US locale? More information about this proposal is outlined in #357. What do you think?

These are the source strings for StreetComplete for street parking (parking:lane):
