I’m looking at responding to this UR. Although there is no text there, I suspect the user is reporting about the route. Why would Waze take this long road? Is it an optical illusion that it is longer?!
I considered traffic issues but the livemap confirm this route is optimal at all times of the day.
I’ve been looking at this one for a while, but waiting until I had something concrete before replying.
For some reason, Waze is refusing to route through the two roundabouts on the edge of the park in the SE->NW direction. We (I’ve been consulting with Timbones) can’t work out why.
I’ve been slowly deleting and rebuilding the area bit by bit - slow because I have to wait for a tile update each time before I can retest.
So far, I’ve:

PS I’m really pleased to see you picking up problems in the area. I’ve done a few, but I don’t really want to be dealing with UR’s 450 miles from home!
I know the area quite well, but my last access dropped off at New Year and I won’t be back there until the end of May.
Unfortunately there doesn’t seem to be a great amount of editors in that central Scotland belt, so good on you evonic.
Oh cr*p… Nobody warned me about Scotland! 
I’ve only recently been there so I’ll have access for a while yet I suspect.
Well that gives you three months to get through the backlog of UR’s in the area 
Scotland has given me the majority of my editing points, so have fun. 
Double roundabouts have been causing routing issues for a while.

I looked at one in Southampton a while ago and rebuilding didn’t work.
What did finally work was to dual the joining segment… but we don’t know why :?

Two one-way segments has worked for me when rebuilding broken double-roundabouts. I’ve done about 5 I think.

iainhouse came up with a theory as to why rounding between roundabouts might not work. I’ll leave it up to him whether to share this unproven hypothesis as we haven’t been able to test it.
In order to test it, I needed first to revert the Stirling roundabouts to having a single connector road between the roundabouts, at an angle of 90 degrees to each of them. The idea was that Waze wouldn’t route through them. Having proved that it didn’t work, I was then going to try a change, which if it worked would have supported Iain’s theory.
Unfortunately Waze decided to be contrary, and is now routing perfectly. So the UR is solved and we’re no nearer finding out why double roundabouts don’t work sometimes

I’ve had a similar experience in Woburn. I rebuilt them once but same result, then completely deleted both roundabouts and link road but still no joy. Finally deleted everything again and put two one way roads between them and they work.
The original roundabouts obviously worked for years, they hadn’t been edited for ages before I deleted, and other pairs work with only a single link road, so I wonder whats changed? :shock:
