It would be valuable if Waze could find these and identify them as a Map Problem in WME. Much more value to identify this type of problem than a missing road in a Parking Lot or Gas Station...


Agreed...these little extra road segments are nearly impossible to find otherwise. They seem to wreak havoc wherever they appear. Maybe we should name them gremlins?

I'm still getting URs at this intersection that complain about being given right/U instructions rather than a left and right/U/right instructions rather than going straight through.

Upon further thought about this, I believe that there may be a fundamental problem with the waze calculations. First I understand that there is a possibility that the right/U might be on average faster than the left (this is an intersection with its own left turn signal). However, I do not believe that the right/U/right is actually on average faster than going straight through the intersection. It is my understanding that waze does rely on different time data depending on which way you are turning. But, I'm not convinced that this works when entering/crossing a split highway, this is because both left turns and cross-traffic have their delay on the segment prior to the highway. Then both left turns and cross-traffic proceed to the cross-segment. Thus, I'm guessing that waze does not distinguish between left turn traffic and cross traffic when determining the average time that you wait at the light.

Its not happening for me now either. Does seem to be based on the time slice data. I'll see what happens if I ask support about this one.

I have a hard time believing that the route is actually faster.


It's not happening for me right now. Maybe bad speed data for one/more of the time slices? I would try to get Waze HQ involved. I know that might be hard, but I suspect something wrong with data that we can't effect without a wipe it all out and start over.

Sounds good. I just haven't seen them in orange yet.

I just figured something had to be amiss with that junction so I pulled it apart (without saving it) and there it was.

I'm now finding little things like this a bunch of places where weird routing has been reported. That being said, I'm still not sure how you found this one. When I pull apart a junction without saving, the roads don't change - the orange lines just show the proposed changes until I save. I haven't figured out how to find things like this without tearing apart and saving.


What I usually do to find these little segments is I grab the junction and move it or I'll remove segments one at a time and look for odd routing arrows. If you drag the junction in different directions and then let go, you'll see the little stub sitting there in orange. I've found enough of these little segments to look for them any time I have an otherwise nonsensical route.

Thanks all. I've modified the intersection. I hope that solves the problem.
