Re: [Tagging] Do we map pedestrian crossings twice?

[Jack Armstrong]

Thank you, Andrew,

According to the "Sidewalk as a separate way" proposal, which was approved in 2011, 

When a highway=crossing node is present on the main road, a way connecting the sidewalks on the two sides of the road should be mapped. Not to override the well-established meaning of highway=crossing, this way should be tagged as follows:

highway=footway

footway=crossing

However, the OSM wiki “tag:highway=crossing” directly contradicts this; 

To map a pedestrian crossing, place a node within the way representing the road, and set this highway=crossing tag on the node…

footway=crossing and cycleway=crossing are sometimes used on ways which lead from a sidewalk to the crossing node (the node which has this highway=crossing tag). This is not the preferred way of tagging.

Is this a simple case of information not being transferred from the approved proposal to the wiki?

I have no preference on how a pedestrian crossing is mapped, but I am keen for the wiki to reflect accurate information. If we are following the approved proposal "Sidewalk as a separate way”, does anyone have objection to the wiki being changed to reflect this?

Cheers

Apologies if this has already been discussed. I searched the tagging list, but couldn’t find it. 

Users have been adding pedestrian crossing tags on ways in addition to the street connecting nodes. In effect, a single pedestrian crossing is tagged twice. To me, this would seem contrary not only to the OSM wiki page, “Tag:highway=crossing”, but also contrary to, “One feature, one OSM element”.

Example:

https://www.openstreetmap.org/edit?changeset=86290585#map=20/39.63167/-104.89726

I’ve been told by a user, anecdotally, there’s a Slack group that decided this is correct. To my knowledge Slack groups do not supersede the OSM wiki. I assume mapping a crossing twice is incorrect?

OSM wiki: tag:highway=crossing
