Tactile paving on steps quest

[arrival-spring]

Fixes #3534

My first attempt at an icon (combining tactile paving and steps icons)

Despite discussion in above linked issue, convention does appear to be to tag it on the way tagged with highway=steps

It was added to the steps page of the wiki in 2009 and to the tactile paving page in 2010 and marked as being specifically for ways later that year.

There's been no discussion on the wiki talk pages about this and it's been tagged on over 18,000 steps.

In addition, it's not a primary feature and there would likely be no other tags on the nodes at either end of the steps.

It affects also crossing ques, but is no really correct when only one side has paving?

[arrival-spring]

Probably incorrect is the right thing there. The wiki has "or if only one sloped kerb at a crossing has tactile paving" as an example of incorrect.

[westnordost]

I think this is wrong. The tactile_paving should be one the first and on the last node of highway=steps, no? Just like it is for kerbs.

OT, but I'd appreciate some clarity/a new option for this (I normally just tag no as it's not yes). Also on a crossing with an island, if its only on either side but not on the island which is right?

Whilst that would make sense I can't see that it's documented anywhere and has barely been used at all like that.

Comparing highway=steps and tactile_paving=* : https://overpass-turbo.eu/s/1g8b (388 ways in central England)
With nodes which are members of highway=steps where node is tagged tactile_paving=* : https://overpass-turbo.eu/s/1g8c (23 nodes in the same area)

And most of the latter are in fact places where steps end at a crossing and tactile_paving refers to the crossing.

Granted, more detailed mapping would separate the end of the steps from the road, but there are plenty of places where this is not the case.

In that same view and excluding crossings : https://overpass-turbo.eu/s/1g8d I find 4 nodes

Therefore doing the quest like that would both lead to issues with where steps meet a road (or such places would have to be excluded) and is also inventing a new form of tagging.

There was a bit of a discussion here: #2738

I'd support having an other answers button of "Tactile paving only at the top or only at the bottom" and similarly for the crossing quest "Tactile paving only on one side" which would tag incorrect after a confirmation.

tactile_paving on ways rather than nodes makes the whole thing more complex (to record, to interpret) while less helpful:

• There'd need to be a tag for "on one side only" (as you mentioned)
• What to do if the highway=steps way is split up into e.g. 3 segments for whatever reason? Are they then all incorrect because there is only tactile paving at the very beginning and the very end of the steps as a whole?
• What about a footway that joins in at the middle of a highway=steps? If the tactile_paving=yes is on the steps-way, does this mean there is also tactile paving at the point where the footway joins the steps? In any case, it would be useful to record this info, no?

I reckon tactile_paving is not really used on steps yet and/or people haven't really been thinking about this use case, so let's delay this ticket after a discussion about this has been held in the tagging mailing list, the wiki or some other linkable medium where people (interested in tactile paving tagging) might tarry.

I'll close this as I don't think I'll get into tagging discussions about this.

Maybe someone could add the 'blocked' label (I don't think I can) - and also to the linked issue.
