If in the map editor the allowed turns had some additional functionality....

1. Time restrictions.
2. An indication of turning ease...
A. Allowed but not recommended
B. Normal
C. Best place to turn

Along with this I'd include

Make left turns where there's a left turn signal.......

I like the avoid left turns onto major traffic routes idea as waze does NOT in fact learn to avoid such. Whenever I leave my apt waze always gives me a route that includes a left turn onto a major route. I occasionally play along and sit and sit waiting for a gap to make the turn in order to teach it that such a route is not adviseable during rush hour, but it has never given me an alternate route.

It doesn't even learn that going one block further west before attempting the turn will almost always get me turned faster due to a light managing the flow of traffic. No light needs to be plotted as traffic turning left there gets through every cycle (maybe two at most on really busy days), as to sitting for two, three or even four cycles of that same light while waiting to turn at the intersection Waze suggests.

I agree with this assessment. Waze had never learned my preferred route home after almost a year. It will more times than not still send me an alternate way.

I have to say that restricting left turns on heavily traveled roads until you get to a controlled intersection seems like a good idea!

I wouldn't want to be the waze guinea pig stuck and nervously waiting for a chance to scoot across without causing an accident when you could've been safely led several blocks down the road by going to a traffic light.

Just one of those things I've tried but not worth the aggravation! Or an accident possibly resulting in this type off dangerous move.

* All other GPS systems use maps that are usually years out of date after you use them for a few years (or spend hundreds of dollars for updates).
* No GPS that I know has the knowledge of what intersections have lights vs not.
* Unless there is a database of the information as to where are traffic lights, it would take years to have Waze editors mark every intersection with a traffic light or stop sign. It is much faster just to drive the area and let Waze determine people are not getting through that intersection in any fast time.
* Only Waze can give you current actual traffic flow information on any street (not just the major highways and roadways) helping you identify where to avoid.

For all the things people say Waze cannot do for them, I can see the 10x more things it already does do for us that people already forget. :mrgreen:

If you avoid a route and always pick a different route, Waze will learn the average speed of the other route is faster.

Waze is working toward time-based turn restrictions. The other sounds nice, but will be highly subjective to many variables not visible to editors. From prior conversations it is believed that if a turn takes longer than an alternate turn to the same point, Waze will eventually route that faster path. As always drivers need to make best judgment for any maneuver in traffic.

Since this has come up a number of times, I created an entry in the FAQ. If you want to discuss the Wiki entry on this topic please go to this thread in the Wiki forum.

It's just a big time waste unfortunately - I never realise until I turn onto the street that it doesn't have a signal, so I'm stuck at turning around and trying to find another street that will let me turn left - do not all gps systems have the information that an intersection is stop signs or signals? I don't know.

I really value Waze's routing capability especially in friday afternoon traffic, as it can get me places via very creative non-freeway routes in good time - everything would be pretty much perfect if I could avoid the left turn situation.

I have to jump on here and heartily agree that this is sub optimal.

I live in the Los Angeles area - during most times of the day, but most definitely rush hour, it is not possible to make a left turn at a stop sign (no electronic signal) onto, or go straight through a major busy road (think crossing 4 lanes) as Waze constantly has me do.

I can tolerate the idea with a signal, but not where there is no mechanism to stop the traffic I'm trying to turn across.

A quickly accessible option to toggle that on or off (together with highways on or off) would make all the difference.

Ahhh good to know. Any link at hand for that information? Any idea if it's again something NA only or generic?
