If would be fine for an administrator to break out the various diversions into a separate thread.

I came across this bug in the last few weeks on a route I often take.

There is a road that passes a fast food drive through and a small loop around the building for the actual drive through, causing the same endpoints problem.

I would drive down the road and turn left onto that small loop and then wait. I would try to route to my next destination from there which would require me to turn right from the loop back onto the road back the way I came.

But waze would insist on only turning left off the loop onto the road, sending me far out of my way and doubling back much further down the road instead of just turning right to get onto the road.

It seemed as if waze was determined not to route me across a segment when I was on the other segment that had the same endpoints.

This happened every single time I went there. I then went and edited it by adding a new node on the loop to see what happened.
Since then it has always routed the much saner and shorter route by turning right from the loop back up the road.

So this same endpoint segment problem is still present it seems and adding a third node definitely fixed it in this case.


This is the loop
I would come from the east then turn south into the loop.

I just saw this thread...

Recently (last few months) there was a problem with two-way sections of ramps not giving the proper instructions - missing keep right/left on splits, missing turn right/left to enter/exit the ramps. All these problems were solved by removing the two-way sections of ramp.

Could you point me to an example of a place where this might be/would be/has been a problem? Not that I don't believe you, I just can't picture a situation where it could be.

I have seen problems with ramps leaving out important instructions, but it hasn't been with two-way ramps. Look at the UR here, keeping in mind that the two selected segments were Ramp type when I left it: https://www.waze.com/editor/?lon=-90.05 ... 6,57649175

Notice the lack of the "keep left" instruction onto the freeway.

That actually explains a lot. Waze avoids routing you in a way that bring you back to the same junction going in the same direction. Apparently, the bug is that when it reroutes you, it includes the junction that you already traversed (or that is the other endpoint of the segment that you are on); it shouldn't. But because it does, you cannot be routed around a loop.

It's because the angle wasn't steep enough at the time. Now it does do as you'd expect and say "stay left".

I don't think any angle would give a stay left instruction if the two segments in the permalink were ramp segments. The road type continuity would make the ramp to the highway the best continuation and suppress the instruction.

It shows a stay left in livemap instructions.

In which direction, westbound? Because Jason increased the angle to the current one while they were still ramps, tested it, and it still didn't give the "stay left" instruction. I tested it too, I think.
