I can't verify, but is it possible this is related to getting alt names used for detour prevention? I know there was a detour I reported that Waze stated they "some turned off feature in the detour mechanism." Because this has to do with alt-names and the recent discovery of best continuation using alt-names... I feel like these are related, and there has been some unexpected byproduct of the "fix."

Is there full confirmation from Waze that this is operating as designed? I think this is a bug.

I posted my concern thread in the GC forum.

Certainly. I doubt we're going to get a response until late this week or maybe next.

I cannot wait until we get the Junction Box so we can remove wayfinder segments completely.

I have some comments.

First, this page was created by waze staff and has always contained some errors. I think the best course of action is write a new page and revert the old page (which I can't currently access) back to the way the staff provided it for reference as the guidance we actually received from waze.

Despite what the original page states, there doesn't have to be a "best continuation." In other words, in the right circumstances you can get an instruction for every exiting segment for a particular s-in.

"The angle between this segment and s-in is smaller than the angle between s-out and s-in" is a bogus requirement. I've never found an example where the relative angles have any effect at all.

Basically, if s-out is the only exiting segment with a turn angle of less than 45 degrees then you get no turn instruction for s-out. If there are multiple exiting segments with turn angles of less than 45 degrees, then if one has a better street name & road type match then it will not get a turn instruction. If there are multiple exiting segments with turn angles of less than 45 degrees and there is not one with a better street name & road type match, then you get a turn instruction for each exiting segment.

You get a "turn" instruction if the turn angle is over 45 degrees regardless of whether the street name and road type matches.

I have never seen an actual example of the turn instruction not given at a T into a one-way road.

qwaletee wrote:Just to give an example of how the angles work that may be counterintuitive. Say you have a girl in the road, but both forks are right of 180 degrees. The main road is bent at a 140 degree angle (call this northeast for simplicity). The branch is a few degrees right of center, call that NNE. Even though you have to turn slightly RIGHT to take the branch, the instruction is to keep LEFT, because it is left of the Best Continuation. That's the whole point of the best continuation, to provide a reference point compare to for right or left. It says nothing about how sharp the driver maneuver is.

But there are no* examples of instructions that actually work this way. A route from any s-in to any s-out that gets an instruction and deviates to the right, gets a "right" instructions. A route from any s-in to any s-out that gets an instruction and deviates to the left, gets a "left" instructions. Where the "best continuation is (if there is one) has no effect.

*The only exception may be where the angle is zero, in which case whether you get a keep/exit/stay right or keep/stay left may depend on whether there is another segment to the right or left.

This is a possibility, however if we know the page has errors, how hard would it be to get an updated accurate version from Waze staff?

In my experience, extremely hard.

Here is my take on the process:

You used to get a exit from a ramp to a street type. I'll have to test to see if that is still the case.

Here's a more complex version with the "best continuation" diamond expanded.
