About half the UR's I am seeing all over Central Florida, Orlando down to Fort Lauderdale, are regarding this issue. In some cases, the users are starting to get pretty frustrated over it. The only advice I know to give them is to change their preferences to shortest instead of fastest routing in the app, but doesn't that really violate the intent of Waze? I mean Waze is supposed to be a commuter app primarily that helps you avoid traffic issues.

At some point we need something more to tell the frustrated users or they'll just quit using the app for this behavior.

[Deleting this as I thought about it more...]

Livemap doesn't route like this, so it's possibly traffic-related.

This could be the typical right+u-turn is faster than waiting for the left.... Until someone takes the route a few times, or several people follow the route suggested, Waze will continue to think it's faster. It's all about the math. :)



Aren't there any complaints that Waze will never say "turn left" here?

Not an issue since the left turn here is allowed and the livemap shows that the router is sending people that way instead ;)

I noticed that too, but didn't bother to post about it since it can't be restricted unless u-turns aren't allowed.

I just found a UR posted today for a very similar issue.

Screenshot attached shows a right turn through a roundabout for a "u-turn" then straight across the intersection. This may be traffic-related because depending on the time of day, the left-hand turn may be a long-ish wait.

I doubt it here, unless routing server has changed. That roundabout is not new and has never been an issue ever before.

Could they be doing what I've jokingly suggested in the past and doing some randomizing/round-robin algorithm to simply spread traffic around relatively similar routes?

That intersection in Torrington has been causing issues for a while - I finally removed & rebuilt that segment of Christopher Rd as it was showing REALLY bad speed data (like 2mph bad)... Give it some time.

I have examples of this popping up in south Florida as well. I'm glad I found this thread to see how frequent this issue has been occurring. Hoping that CBenson's latest post from Waze staff will prove to rectify this routing issue. Waze should almost always chose the left turn. I think that the driver should make their own decision approaching a light to wait for a long-queued left or a right on red + U turn based on the traffic and their driving style. I drive more aggressively and may chose that right on red "shortcut" but most people I know (and when are my passengers) denounce that practice as impatient and risky.

UR from Jan 1 in Coconut Creek, FL:

That right turn + U turn adds nearly 1km to the route instead of just taking the left. How could that possibly be time-saving?

are they collecting said data from this thread? if so, should we keep posting all occurrences we run into?

If any of y'all come across one of these yourself, leave a UR and make note of the time/date and your approximate route at that time, then post all that here, if you like.


How about URs that others have posted that fit the same problem?
