I have seen also junctions so close that even with 5m/10ft zoom it is not possible to select them separately but you always get only one selected. Then I usually just change one segment geometry so that I can get another junction out of this. Don't remember the map problem number but it had its own code even AFAIK.

Hi!

regarding "parking lots roads" - indeed the their penalty is very high ( in order to prevent waze to make "shortcuts" through malls), but we are working on a solution that if you are already located on a parking lot road, you will get a logical route (meaning that waze wont try to avoid these roads)

thanks,

Ori.

There was some confusion on what the issue was. Unfortunately it is not a routing on/through a parking lot road. There is a routing issue with routing through a node that has a parking lot road on it. We might have figured out that it's a connectivity thing, but if you guys could validate it based on your "super" :) tools. It would be appreciated.

That's great @Ori, but it wasn't the problem being reported here. Here there was a major road running past a parking lot loop (crescent), but routing was failing to go along the major road past one of the parking lot roads.

What we found is that connectivity looked correct when looking at the main road but not when looking at the parking road. The parking lot road would show you could exit and turn left on to the main road. But the main road did not show that your could come left out of the parking lot road.

I have never seen inconsistent connectivity before. It is fixed now.

So it is great that you will resolve driving through connected parking lot roads. But this was not the problem here.

Yes, this one is fixed and it was related with "loop" problem. After adding additional junction all turns went okay.

Still I have the same intersection problems where I checked all segments and there are all turns allowed. No one way roads or any other tricky things:

And one more I know:

http://world.waze.com/livemap/?zoom=9&l ... g=98419881

This is more complicated as there are actual turn restrictions also.

This looks like a routing bug to me. I'm going to email support.

It will route North to South along Kadaka Tee between A. H. Tammsaare tee and Akadeemia tee but not South to North.
Connectivity is good.
None of the roads have been edited for 2 months, so it's stable.
My guess is that not only is the route algorithm weighted highly against driving through parking lot roads - it also has a high weight against going through intersections with parking lot roads. Which is just wrong.

Good spot zcougar
