[Tagging] key:destination Signpost question

[Kam, Kristen]

Good Day,


I am writing to receive additional clarity with regards to using the 'destination%' tag in the context of signposts.

For a while now, the status quo was to use the 'exit_to' tag on the node where the signpost would be (bifurcation points typically) when representing a signpost location and information. This tag is being deprecated (hence this wiki page). Using the destination tag on the ways (e.g., motorway_link) can provide one with the signpost information, but how would one easily identify the signpost? Are we going to use the 'destination%' tags in conjunction with the highway=motorway_junction tags on the nodes where the bifurcation point is? This isn't clear in the main article for 'Key:destination'.

My thoughts are that tagging both node (bifurcation point) and way(s) (downstream from node representing bifurcation point) would make it easy for downstream OSM data users to identify the signpost locations and the relevant signage information. An existing example (not edited by me!!) is along the lines of what I'm thinking:
·         node 140772317<http://www.openstreetmap.org/node/140772317>, represents the bifurcation point
·         way 14406219<http://www.openstreetmap.org/way/14406219>, represents the right part of the fork/bifurcation
·         way 293468020<http://www.openstreetmap.org/way/293468020>, represents the left part of the fork/bifurcation

Here is a visual example of the bifurcation with the OSM ways and node cited above:

Please note, I also posted here:

Best,
