A quick look at the ‘not split’ shows me no reason to split it. All the cross roads are handled well.
A quick look at the split one shows me no reason to unsplit it. There are at least two road that would require ‘no left turns’ that are handled by the splitting just fine.
I would leave them both alone unless there are a lot of problems in one case or the other that would be best handled by splitting or unsplitting.
In these cases, the median and GPS tracks justify a split whereas the ‘KISS’ (keep it sweet and simple) says do not split. If I was mapping the area from scratch, I would probably do exactly what was done in both of these cases.
In my personal opinion, it boils down to: whatever works to make sure that the drivers get the directions they need.
Next, to whatever ‘looks best on the drivers screen’.
Next, to whatever ‘looks best in the editing views’.
If it works, flaunt it.
If it doesn’t work, it doesn’t matter how nice it looks or how well it follows the ‘editing guidelines’, it needs to be made to work.
Caveat: sometimes ‘what works’ changes.
Often, no one really knows what works because the interactions between the database and the routing programs is ‘rather complex’.
Caveat: My guesses, which are stated above, are only based on observations ‘from the outside’ and a few years of experience working with computer programs (since 1964). I have no ‘inside information’ as to how WAZE works its magic.
