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.

Is it possible it's faster, if the left turn can only go on an arrow, and the arrow is short, then it could takes several minutes to take a left (I know an intersection where it takes over 90 seconds to get an arrow (and can only go on an arrow), but also takes 3 cycles to get through it if your in the back. )

If there is right on red, one could take a right if clear, then cross all the lanes, hang a u-turn, and go straight through the green light...

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.

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?

Hmm. That can't be good. How did you find it?

That right turn w/ u-turn is actually the 3rd best route through that intersection. If you stay straight through to Pasadena Rd, there is a valid u-turn that could be made at Oak Ave. There has to be something that is keeping Waze from routing straight. The turns are also enabled with that segment too, but I have to imagine that little segment doesn't help matters.

I just zoomed in real close to the intersection and found this little extraneous segment. Could it have some effect? It's only connected on one end.

I don't understand how this intersection would solve my routing problem. Both routes in my example (simply making the left turn or making a right turn / U-turn) are valid permitted routes. Its just that the right/U-turn makes no sense from a practical routing perspective. What waze is essentially doing is giving this route. I don't see that your intersection would prevent this.


I have to admit, when I looked at this Saturday night, it was routed correctly so I guess I misunderstood what was happening. I didn't re-check it before I posted my examples, and now that I see it, I don't think they'll help. :oops:

The only possible thing I noticed is that on the Live Map, the section of East West Blvd between the two sets of lanes of Gov Ritchie Hwy has an avg speed of 0 mph. I realize that info isn't necessarily what Waze uses, but it may have some merit. Perhaps deleting and rebuilding the 3 segments from before the intersection through the turn may help?

That intersection is complicated, but some of the changes you've made seem to go against the #1 guideline for mapping. I see no purpose to this segment for example. It's just to give a left turn instruction?


The simple answer is yes...but those little segments also prevent crazy routing issues. Several URs popped up in that intersection with very bad routes through it. By losing the intersections, they simply can't happen.

Also take a look at these two junctions...same concept. Some of the routing that Waze was coming up here was just bizarre.
