Limit tactile pavings to set of countries

[westnordost]

Tactile pavings are also something that does not exists in many countries.

I did not research here yet. Perhaps if someone wants to help, he could get into a Google Streetview car, drive around the world and write here of his findings.

[westnordost]

I'll start:

Yes: Singapur, Hong Kong(, Malaysia?) No: all of southeast asia

[dbdean]

Yes: Australia, New Zealand

[rugk]

I think for such things, we really need https://github.com/westnordost/StreetComplete/issues/633 as a kind of in-app "survey".

[matkoniecz]

Maybe it would be useful to check what is currently tagged in each country (run overpass query)? And blacklist ones with heavy *=no usage?

[matkoniecz]

Yes: Poland (for crossings)

[westnordost]

I think checking intersections in bigg(er) cities with Google Street View would be the most efficient.

If that is main reason, rather than doubts about data usefulness I made https://gist.github.com/matkoniecz/6fc0e5f3f2f399849cf8117731fc5afe and https://gist.github.com/matkoniecz/a81ae6516fa8d39567140c2ac8dd293c

Quick tag check suggests:

for highway=crossing:

whitelist: Slovakia (SK), Austria (AT), Hungary (HU), Poland (PL), Germany (DE), Czechia (CZ), Switzerland (CH), Belgium (BE), Sweden (SE), Brazil (BR), Russia (RU), United Kingdom (GB), Ireland (IE), Lithuania (LT), Australia (AU), United States of America (US), Argentina (AR), Italy (IT), Singapore (SG), New Zealand (NZ), Spain (ES), France (FR), The Netherlands (NL)

blacklist: Albania (AL), Ukraine (UA), Portugal (PT),

for bus stops:

whitelist: Poland (PL), Germany (DE), Switzerland (CH), Russia (RU), United Kingdom (GB), Ireland (IE), Australia (AU), United States of America (US), Argentina (AR), Italy (IT), Japan (JP), Spain (ES), France (FR), The Netherlands (NL), Spain (ES),

blacklist: Brazil (BR), Portugal (PT),

Whitelist is proposed for tactile_paving=yes used more than 100 times where at least 5% of tactile_paving=yes/no is tactile_paving=yes.

If such list/data is useful I may run it also for cycleways or share code used to create it.

[westnordost]

Wow, that is very cool! How did you put this together?

For cycleways, it would indeed also be helpful!

[matkoniecz]

Wow, that is very cool! How did you put this together?

[out:json];relation["admin_level"="2"][boundary=administrative][type!=multilinestring];out; to get list of countries, fetching all tactile_paving= objects in each country ("tactile_paving= in COUNTRY_NAME" on overpass) and counting how these objects are tagged.

I am currently trying to make my code publishable (note that Ruby is required to run it).

[matkoniecz]

Note: I updated list in https://github.com/westnordost/StreetComplete/issues/750#issuecomment-355823893 , by mistake it included twice data for highway=crossing (both for highway=crossing and highway=bus_stop). Now highway=bus_stop contains correct data and list has both country codes and less cryptic country names.

[matkoniecz]

If whitelist from https://github.com/westnordost/StreetComplete/issues/750#issuecomment-355823893 looks like a good list of countries with enabled quest I make a PR that limits quest to this list of countries.

[westnordost]

OK! :-)

[matkoniecz]

I wonder what countries should be split in regions here. I suspect that USA may be considered as one entity and China, Russia should be split.

[westnordost]

Russia cannot currently be split

@dbdean

Yes: New Zealand

Also for bus stops?

[dbdean]

I don't know about tactile paving for bus stops in NZ, sorry.

[matkoniecz]

So bus stops in New Zealand are almost always without tactile markings?
