Allow tagging crossing without specifying variety (just highway=crossing)

[matkoniecz]

Sometimes memory or aerial is not good enough to specify exact one 0 for example presence of traffic signals may be not entirely clear.

On node within way:

👍 This would require to make the highway/_crossing.json preset searchable and potentially renaming it to something like Crossing (Unspecified Type).

Just “Crossing” is probably sufficient. There are some other unspecified-type presets that we give simpler names, such as “Building”. But if we need to differentiate, I’d suggest saying something about a “path–road crossing” or somesuch, to differentiate it from “Railway–Road Crossing” and “Railway–Railway Crossing”. (The standard real-world term for these is “road crossing”, but users could be confused about when they’re supposed to use one preset versus another.)

What about "Pedestrian Road Crossing"? path has a bit messy implications as a term, some are sure that it is invalid for sidewalks (which is BTW causing problem with people retagging highway=path surface=paved bicycle=designated foot=designated segregated=yes)

[1ec5]

“Pedestrian Road Crossing” would be an accurate description of most occurrences of highway=crossing. However, in many regions, it’s also normal to use highway=crossing for where a cycleway crosses a road or a footway crosses a cycleway. On the other hand, the icon already depicts a pedestrian, so it’d be no more confusing than before.

Is it possible to have different preset match based on way where it is a vertex? Probably no.

No, that's not currently possible in the tagging schema, unfortunately. iD could however implement a validation rule that any highway=crossing node should always be on a highway=* way (and any footway/cycleway=crossing way should intersect a highway=* way). iD could also suggest a fix to convert the highway=crossing mapped on – say – a railway to the appropriate key (railway=crossing in that case).
