Hi!
In Road configuration section:
Waze will penalize a route with two left turns in less than 15 m


Please have a look at this thread: https://www.waze.com/forum/viewtopic.ph ... 75#p645880

Basically, Waze penalize two left turn only if both of those turns are very close to 90 degree. IMO the spread is +- 5 degree or even less.

They are now 90+-1 and U-turn is not allowed, but when they were ~85 degree the U-turn was allowed. here are the links from the OP:

Anyway, the Wiki phrase "Waze will penalize a route with two left turns in less than 15 m" is not quite correct, since Waze will not penalize ANY left turns, but just turns which are very close to 90 degree.

Sorry, I didn't follow the conversation, I just found the thread and wrote a comment about the "Routing Penalties" Wiki page for Kent.

[New page] Routing Penalties

Postby kentsmith9 » Sat Mar 15, 2014 10:25 pm

From this thread we concluded we needed a Routing penalties page.

There is one image I am proposing we add for the 15 m U-turn prevention, but I am not sure what other images would be good. I am currently editing the page for Wikilinks. From here we can discuss any other changes we think are needed.

I added another image and finished the Wikilinks.

Due to some recent experiences in NYC, I'm not sure the 15m left, left penalty still functions. We had a row of blocks with H intersections, the middle segment being 14m, then all-of-a-sudden got URs at a few different one showing Waze routed U turns through them (left left). We had to replace them with bow-ties to solve the issue.

Remember that the page is talking about how routing works with penalties. The Left-Left-Turn is simply penalized over other routes. If the other routes are too long in time, then the 14m or less distance penalty is better than some other route.

I believe we don't know the penalty amounts for the different factors beyond a few of them. I am saying that a bow-tie intersection will enable you to set a no-left turn to the other direction which is just another penalty. Hopefully that bow-tie's left turn restriction (red) has a higher penalty than a 14m segment length. If true then your problem should be solved.

Just a few days ago I had to point someone to this new page because they could not figure out why Waze would not do a Left-Left turn and instead did it on the next block. First turn was 14m and the second one was 17m. That would say it is working.

You may have seen a routing anomaly for a few days.

Thanks. I posted additional questions in the other thread to better understand their findings. Once I get more data I will review what needs to be done for the WIki.

I have not. Maybe someone else did.
