We have a different situation in Japan (normally/mostly the name belongs to
the traffic signal system) and a different situation in Korea (the name
belongs to the junction). Currently in OSM we use yet
highway=traffic_signals for traffic signal names in Japan. And we use yet
junction=yes for junction names in Korea. This is yet an established
tagging. But it is used currently only on nodes (not an areas) and works
well only for simple situations.
The difference between traffic signal names and crossroad names is
meaningfull. The rendering is not the same. In openstreetmap-carto we have
currently rendered the name together with an icon for nodes with
highway=traffic_signals. But we have just the name without any icon for
nodes with junction=yes.
The proposal/RFC simply extends the existing and yet established tagging
conventions for nodes to be now used also on areas. It extends both
(junction=yes and highway=traffic_signals) independently, but guards the
difference between both. This was the intention…
