Hi Kovoschiz,
I noticed you added junction:ref= NT405 to https://www.openstreetmap.org/way/158584374, https://www.openstreetmap.org/way/158584309, https://www.openstreetmap.org/way/158584377, and https://www.openstreetmap.org/way/524742248. Based on the Key:junction:ref wiki : https://wiki.openstreetmap.org/wiki/Key:junction:ref that tag combination should be used for exit numbers. Is there a reason you decided to use this tag? I also noticed https://www.openstreetmap.org/node/6705213952 has the ref=NT405 information on it and was curious what it refers to?Thanks,

First of all, I think there's some issues with the Wiki. It is a "in use" key only, and the associated proposal is only in draft stage and is very old.
If you compare definitions, you will see there are some inconsistencies. "junction" itsel refers to a junction, nothing more (see `junction=`). `highway=motorway_junction` is a historic mistake of referring to exits (UK conveniently mixes up "motorway junction" and exit numbers), and this is apparently what the `junction:ref=` page is referring to. Furthermore, when you look at the page, it mentioned `destination=`, however "junction" and "destination" are really different concepts. No one really knows how the page's author comes to the conclusion, despite >20k uses of `junction:ref=`.
In Hong Kong, signalized junctions and crosswalks are numbered on the ground by the set of traffic signal system. Someone took the time to add them. Since them, at least there are some attempts to incorporate them properly (the standalone `note=highway=traffic_signals` or unchanged `highway=traffic_signals` nodes. Recently, I'm settling towards using `traffic_signal:ref=` instead of `junction:ref=`, so they should be changed in the future.
Anyway, no one really uses exit numbers much in HK. They are purely a systematic construct for the sake of it. You will notice interchange and roundabout names, as well as street names at times, are pretty inconsistent. -

(You will see J-numbers being used to refer to the entire interchange in the UK. Exit numbers are meaningless to use in this respect, and they don't cover entrances and entry-only connector roads.)

To be consistent, for the time being I feel like one should use `motorway_junction:ref=` to go with `highway=motorway_junction` when referring to exits.
Shockingly, apparently `highway=motorway_junction` is also de facto only. You will some discussion on this topic. -

Hello Kovoschiz,
Thanks for the quick and detailed response. It is interesting to learn about the numbering of junctions and crosswalks. I noticed on taginfo (https://taginfo.openstreetmap.org/keys/traffic_signals%3Aref#values) more of them that are tagged with `traffic_signal:ref=` in Hong Kong. Would you like me to go ahead and edit those four ways I mentioned earlier?
Thanks again,
