The North end of https://www.openstreetmap.org/way/629622890 is parallel to a short existing stub road. In reality, these two are one and the same and this is clearly visible, if you load GPS traces and correct the imagery offset with them. Clearly, you did not do that. I have now connected the two roads.
West end of Way: 629622938: see https://www.dropbox.com/s/hoe0jxc1ys9fc90/OSMway629622890.jpg?dl=0
Road สห.2006 existed before you added the two streets on the right. You put a dog leg into the highway and the residential road crosses it before joining. Both of these are a big no-no. All you have to do is merge the two nodes and then line them up with the image. There are just about enough GPS traces on the junction N of the roundabout to let you do that. (I'm leaving this one for you to look at to learn.)I have moved almost all roads in this area to line up with the offset.
You are drawing the roads nicely now with sweeping round curves. Once you leave out the extra nodes in the straight sections and line the whole thing up with GPS tracks it will be perfect. I see this was all done 10 days ago and it's a big improvement over edits I have seen from your colleagues a year ago.
Kind regards,
Peter. -

https://www.openstreetmap.org/way/629622905: See how you have connected the street to the one-way section of the highway? https://www.dropbox.com/s/s83jex32ya2ave0/OSMway629622905.jpg?dl=0
This prevents routing a right turn out of the street, as the routing software will not route against the one-way street. Trying to turn right into the street you would get a confusing instruction to make a U-turn, then immediately turn left, when in reality only a right turn is required. You can again see an imagery offset. Once corrected, the two nodes at the junction are on top of each other, so it's safe to just merge them.To contrast this, check out the two roads branching off the hway N of this. The median barrier wall extends past both junctions, so it is physically impossible to turn R here. (without the drawn wall there would be no way of telling, because the median barrier doesn't show up in the images. Given this is drawn as a dual carriageway I would guess that you can't turn here and still draw it like this, but you could also draw U-turn ways. I only know it's there because I have been there several times myself.)
Moving one street S to https://www.openstreetmap.org/way/629622864
The W junction is clearly in the bend, so we'll merge the two nodes here.On the E end the junction is a cross roads, not with an offset, so we'll merge these two as well and move the whole Rd S to where it should be.

Comment from RVR002
Hi Beddhist,
Thanks for the in depth feedback. This is very helpful to us for improving the quality of our work.
I've responded to a few specific examples here.
way 629622890: Agreed. This should have been noticed and attached to.
Way 629622938: Stephan mentioned this already, but this was a result of realigning the data.
Way 629622905: For this one, there is a car turning in premium so we can confirm there is not a barrier but if not it would be very difficult to tell how far the barrier actually extends on this road. In situations when it isn't clear but the split is close to our attaching road do you recommend that we adjust it or leave it attached to the one way?
Thanks again for your feedback!

I've taken a look at your flagged edits and appreciate your time and feedback. I can assure you that I learned from the examples you flagged, and their reasoning, and will make sure to be more careful in similar circumstances and road qualities in the future.
We work with a limited toolset, which improves almost daily, but we strive to do better and better each day, hence the drastic improvements from a year ago. Again, thank you for your time and extra pair of eyes in trying to make a better map for everyone.

The second problem I flagged above: West end of Way: 629622938: I may inadvertently have caused this when I moved the whole area to account for the imagery offset. I'm sorry about that.
