I changed osm.org/way/87021631/ and osm.org/way/255891762 if that's what you are asking.

>Some editor cuts the trunk link when there is a intersection after leaving the trunk road, even thought that intersection is for bus to leave the bus terminal."
Can you point to the example?
>But after meeting the intersection to route 3, you still edit ching chueng road as trunk link.
Are you asking if it is considered a fork?

For historic reasons, `highway=motorway` is special, so it has to be handled by `highway=motorway_link`. Oi Shun Rd ends at Tai Hong St, and this is a four-way intersection.

>As normally people wont leave the highway and immediately enter it again, and I am just observed from other similar case in different places of hong kong. I just think trunk link acrossing sha tin wai road is inaccessary.
This is for the right turn
>, sha tin road near yuen wo road should be secondary road instead of trunk link,
No, it is an exit from `highway=trunk`, therefore `highway=trunk_link`. However, Yuen Wo Rd to IVE can be `highway=secondary_link`

I did. You need to use `access=private` or `access=no`. See osm.org/way/111601696

Concerning left-hand diverge from a left-hand curve, it would be more realistic to put it at the end. This reflects the off-connection properly. It is also not a lane at the taper upstream. This may be considered a developing parallel diverge if so wished.

Also please don't split un-divded road - use `change:lanes=`, `turn:lanes=` (and relation:connectivity if needed)

`_link` follows the classification of higher class road, with continuity. Other tags are also used for your purposes, as they have been corrected and refined recently. What do you mean by `highway=service`?

Again, continuity of `_link` needs to be observed here. Use other tags as has been tentatively tagged here

This is not endorsed. Continuity of `_link` is required. Alternative tags are used for these.

I would explain further that dangling `highway=motorway_link` ends you may see in eg Airport Rd -- North Lantau Hwy is from historic reasons. For unumbered strategic and major routes (ie `highway=trunk`) sections, `noref=yes` and `highway=trunk` can be used. Kwai Chung Rd -- Ching Cheung Rd is considered a fork, especially because of the boundary of Route 7 defined across Kwai Chung Rd.

Also, notice the `noref=yes` on Kwai Chung Rd -- Ching Cheung Rd

Thanks

Check again now, the only thing you did correct is Roundabout 4 via Kwai Chung Interchange to Lai King Hill Rd.

“Many roads should not be trunk link" Explain this? Do you know how are they classified, or how are Tunnel area treated?
”but you still added it back“ It is you who made those changes, without studying guidelines properly, or looking at their object history. Now you are restoring them again without good reason, or acknowledgement from the other side.

Are you sure? Is it changed recently? It is two-way to access the carpark of Sunway Gardens osm.org/way/86222953

Please use JOSM's replace geometry function instead of deleting the object outright and redrawing it.

These are a bunch of wrong classifications.

Can consider relation:connectivity to be clear.

This is not correct. See osm.org/way/714996652. `change:lanes=` and `turn:lanes=` are tagged, and a no left turn restriction is used osm.org/relation/10686309.
