Un-dividing divided roads

Post by Borgholio
Now that single roads have the option for a U-Turn at junctions, would it make sense in some cases to un-divide roads, at least at intersections? The goal is to eliminate erroneous "roads are too far apart" problems caused by U-turns too far away from the street junction.

Semi-dated thread, but I finally found an intersection somebody made that is a perfect example of what I was talking about.

With an intersection like this, ALL turns are controlled, without having to use "short segment" tricks, etc. I kind of like it, but....
Just a comment about something I see near by: Pretend the segment type of Service Road doesn't exist. It's identical to Street, so if you're trying to have routing avoid it, use Parking Lot or Private, and if it's a "frontage" it likely should be Primary or Street depending on Functional Class.

Not sure what you mean...leave the road divided but change to two-way?

I think I understand now. Question, what about the "V"s left over on either end? Would I simply leave them intact and only un-divide the road at intersections?

It would also be good news for currently split intersections with impossible-to-add u-turn restrictions.

So, what is the general consensus? Personally, I'd like to unsplit most (if not all) intersections to give full control of the turns. Is this an acceptable practice now? There may be times where leaving them split is best, I'm not sure. Just looking for input before I make any of this style of change on a broad scale.

If its working, leave it alone.
Well, I see plenty of "Missing Road" SRs on many intersections. Would fix that by unsplitting the intersection. I would only change them as SRs appear. My questions is, should I?

Unsplitting is likely to generate even more Missing Road type MPs. There's no need to do anything about those unless an actual road is missing.
I'm not talking about unsplitting roads as a whole, I'm talking about joining the 'intersection' and only the intersection, so as to control u-turns, etc. As was the original point of the OP.

For example, both sides being a V like this. (not the perfect example, but you get the idea, I hope)

Don't waste your time on Missing Road MPs unless there is actually a missing road. Just mark them solved and move on.
Ok, new scenario/question then: Would it not be easier to control the turns of an intersection on one node instead of four? I'm just trying to learn the purpose of having any split intersection. Just seems like it adds more nodes to have to check. If there is a specific advantage of a split intersection, that's what I'd like to know. :)
