I think waze’s instruction is misleading on this segment, but I don’t know how to solve it.
If I am on N80 and want to take this ramp, waze first tells me to “exit right” (because coming from a highway to ramp), which is already not exact : it should instruct me to keep right, because there are two straight lanes there, one going straight and the other one turning right. But this is not so bad since it tells “exit right” well before the next exit so you can’t really make the wrong turn.
But then there is this first exit here, and waze instructs me to keep left. And that is very misleading, because at that moment I am still on the right lane of a two lanes road, and I really could move to the next lane. It really should instruct me to “continue”.
Maybe the first segment should not be a ramp so that it can instruct me to “keep right”, but what will it say when the freeway ends end the ramp starts in a straight line ? If it says nothing that’s fine.
Anyway, I don’t really know what to do, but this place needs some fixing.
Did you drive there and got these instructions or is it by looking at this?
Because, if you zoom in, you can see there was already some patch work done, since june.
The major doesn’t go to ramp, but first splits in 2 majors, wich should give you keep instead of exit. But in the name of the segment there is indeed ‘sortie’.
For the second point, i changed the angle, to get a ‘turn’ left, instead of ‘keep’.
i’m not following you anymore… :-S
My second point was about the instruction to get on this segment. Here you will get a ‘turn/exit right’.
Normally you will get nothing to continue straight on, i think.
First instruction is fine, I am instructed to “keep right” when on this segment. I don’t know why, but I was instructed to keep right way too many times, maybe 6 or 7 times, but that’s not very important. Probably because of the “small segment split” trick ?
Then, I was instructed to “keep left” when on this segment, which is what I thought was misleading. I should not be instructed to do anything there (=continue). When Waze says “keep left”, I am still on a two lanes road (even though separated by a continuous line), and I could think that I am on the wrong lane.
When arriving on this segment, I am instructed to “turn right”, which is not good because there is no turn allowed there, it’s just a ramp with one way to go. I think it’s because of the wrong turn on this segment (left is not allowed), but it’s L5 so I can’t change it.
Sorry if this is not clear, but this place is quite a mess IRL also !
How it looks now, it should all be ok… But remind that the actual state in WME is not the one in the Map on the client.
The last update was with all changes untill sept 8th… so our last interventions were on sept 12th… We will have to wait untill the next update, to determin what is still wrong…
The permalinks work for me too. :?:
OK, I did not check the update status indeed. Last time the change was so quick that I tought Waze changed it’s update method to some kind of “rolling-release”. I had stopped using waze for ~1 year, I admit I did not mind going through posts to find out how it went.
I’ll wait until the next update then.
Cheers !
PS : no, I won’t be attending the meeting unfortunately.
I’m currently wondering if this article of the wiki is complete or not :
What happen if
s-out has a different road type & different streetname than s-in
AND none of the other segments (s3,s4,… sN) meet both conditions mentioned above
Does it mean that, in certain case, Waze is not able to determine the Best Continuation ? or do we have a default selection, for instance Best Continuation = s-out ? or anything else ?
This is quite a important point as the Best Continuation is required to run the proposed algorithm below :
What happens if the Best Continuation is not determined (as raised above) ?
In town, where we have a majority of secondary roads (= not primary and not ramp), what happens if s-out is not the Best Continuation and the angle between s-out and the best continuation is lower than 45 degree ?
According to this algorithm we fall in the 6th case, and we should get a KEEP Right or KEEP Left. But we know that we never get a “KEEP something” instruction when driving in a residential area.
So I guess that the algorithm need to be amended with the secondary road situations or somebody need to help me in clarifying the running of this algorithm
The way I understand it, yes, s-out will be the best continuation. It does not perfectly match s-in, but no other segment offer a better match, so it is considered as “best continuation”.
The key words is “one of them will be chosen as better continuation if…”. Since the conditions are not met, there is not better continuation, so s-out is the best one.
That’s the way I understand it anyway, and I believe it makes sense.
Thanks for your answer. You should be definitely right. The key word is “better”. That was a bit too subtle for my poor level of english and i confuse it with “best” :-). Anyway, about the secondary road algorithm, any comment ?
After some thinking about it, I’m finally not so sure that it’s working
Consider a classical Y split of a highway, following the best practices (outbound segments named differently from the inbound one; outbound segments wit angle of 20-30° from the inbound one)
According to what we’ve said previously, one of the two outbound segments will be, one way or another, the Best Continuation (at least, by the default approach that lead to consider the s-out as the Best Continuation)
Thus, if the s-out is the Best Continuation, then the Algorithm leans us that
And all of us know that it’s not true. Following the best practices mentioned above, we know that we’ll have a “KEEP left” or a “KEEP right” instruction.
I don’t know if I trust that page. I have an example in my area where a straight ahead and an angled right produce a stay left and stay right. Primary street and all segments are named the same. Does that fit within the rules Waze provides in the wiki?
I fear that the rules in the wiki are provided by users like us. The wiki is maintained by the community, not by the waze staff. (I will look up in the history who put it there)
If I was on the waze staff, I would also not provide how exactly the internal algorithms of Waze work to prevent other manufacturers copy the work Waze did.
The page was created on 23 January 2012 by Krankyd. It seems like it was copied from an other page but I cant find the original page. The rules he defined did not change, so the current version of the rules is from 23 January 2012.
