Talk:Tag:crossing=unmarked

When to Use

When exactly should this tag be used, and when should it not be used? For example, for crossing service roads to parking lots for shops, should those transitions be considered as an unmarked crossing? And when constitutes a 'recognizable' transition? Any clarification would help I lot I think. --IanVG (talk) 05:25, 15 July 2020 (UTC)

This tag is mostly "introduced" by iD, and crosswalk practice varies among countries, so where you are mapping would be needed background info. A possible advantage of crossing=uncontrolled that I prefer is it doesn't attempt to make this distinction. As long as there's no method of traffic control, it can be tagged as such (although historically, people interpret "uncontrolled" as not controlled by traffic signals, ie unsignalized; disregarding yield and stop control). This makes it potentially useful for flat crossings of (service) roads without any slopes on the sidewalk, that I assume you are asking. crossing=unmarked is typically tagged for eg dropped kerbs, sidewalk edge tactile pavings (which is "unmarked" from at least the carriageway's perspective), and bollards. However, from the more lenient perspective on the definition of a "crossing" (the source of geographically-dependent disagreements), your case can be included. On this wiki, the "without"..."traffic signals" and "transition should be recognizable" clause of crossing=unmarked, and "marked but not controlled by traffic lights or people" on crossing=marked are quite debatable descriptions yet. I only use crossing=marked & crossing=unmarked when the jurisdiction is unknown or unclear to me, and the method of control is unobservable from aerial imagery (frankly this should be what they are for). -- Kovposch (talk) 09:13, 15 July 2020 (UTC)

Real world usage

I recently had a look at how the tag is really used. Checked some locations etc. Looks like it is used more broadly than the description here suggests, so I added a paragraph. See for example http://overpass-turbo.eu/s/19rJ , many more examples - Krakow, Munic, Berlin (Neukölln), Heidelberg, ... --Westnordost (talk) 22:17, 14 July 2021 (UTC)
