Here's my example:

https://www.waze.com/editor/?lon=-79.43 ... s=60499843

Going south on Marlee at Eglinton, the most direct (and always legal) route is to turn right and go south on Oakwood. However, Waze continually tells me to turn left and then right down Winona (and then wrap around on Lanark back to Oakwood). However, Winona turns 1-way 38 metres down the street from 7am-7pm. So I learned the lesson once and haven't followed that advice since...despite Waze continuing to offer it.

In this example, there's no way for the driver to know a priori that this left turn at Marlee and Eglinton is illegal from 7am-7pm. He's then forced to do a u-turn and make a left turn back onto Eglinton into busy traffic.

The bad part of the UR is that it only tells me the date of the UR and not the time. So I can't tell if the person reporting it is in commute hours or not.

Based on the WeeeZer14's parameters, I would rather have the turns enabled, as sometimes the nearest non-restricted turn is several blocks ahead or in my case right turn - right turn - right turn and play avoid pedestrian dodge ball. Which in either case, with San Francisco drive time, can be 10-15 mins of a drive delay.

If the consensus is to disable the turn, there are so many in SF, that, I would just leave them alone until a UR report comes in and fix as needed, based on the guidelines.

That a good question, I'm not sure that honoring any particular turn restriction results in "significantly" increased route. Basically, if a left turn is restricted, you can typically take the detour of three right turns around the block.

However, the turn restrictions do have a significant impact on the routing. For example, take this route. The screen shot is here as the best route changes a lot:

You are much more likely to get the southern route down 9th street and across the 11th St or PA Ave brigdes rather than the the northern route out NY Ave if the left turn from K to 7th here is restricted. Currently, it is not restricted and I'm sometimes routed through that turn onto outbound New York Ave when the turn is illegal. When I ignore the turn, sometimes waze simply has me turn on 6th back to NY Ave, but more frequently, waze will have me go down Mass Ave to the 3rd St tunnel and take one of the southern bridges. So that one turn restriction can (sometimes depending on the traffic) result in vastly different routes.

Oh there is no question that this logic is not universally applicable. But the whole point here is that there is no solution that will always work.

Sure if the turn is illegal from 7am-7pm, it should likely be marked as restricted. But the counter point is that waze is a commuting app. You don't know a priori that the left turn is illegal, you know from experience that it is illegal. Say the turn was only illegal from 7am-9am. Then if the left turn is unrestricted and waze routed you through the turn between 7am-9am you would know to go the other way. However, if you restrict the turn and waze routes you down Ellington to Oakwood at 5pm, you have no way of knowing whether the route through the now restricted turn is faster or not. Again, safety and the added inconvenience to those that aren't familiar with the turn restriction may well outweigh this advantage of leaving the turn restriction open (especially, if as Weeezer is postulating, the route through the restricted turn isn't ever all that much faster).

If Waze is strictly a commuting app, then I wasn't aware. You're saying then that we should damn the inexperience non-commuters and let them figure this out on their own?

Then I would say leave it open and not restricted.

We can only weigh the pros and cons of restricting or not restricting the turn. There is never a perfect answer because the are always both significant pros and cons. I'm saying we should weight the commuter experience more heavily than the non-commuter experience.

Okay, CBenson, I understand where you're coming from. I'm not completely convinced that the interests of commuters are at odds with non-commuters, though. Everyone on the road is Traffic and having confused and wrong-turning, etc., drivers on the road affects everyone.

Anyway...I think when/if Waze supports time-based restrictions, it's going to have a significant impact on the routes offered in the app (for the better). These restrictions can have far reaching effects on the efficiency of the routes sometimes.

Yes! (but please let it be when not if).
I live what Mike said:
Mike-1323 wrote:The lack of time-based restrictions on both turns and direction, as well as the lack of HOV support make Waze much less useful around here. The DC area is full of such restrictions and failing to recognize them mean that Waze can't be trusted to route through certain areas.

Well it seems this is a mixed bag on this issue. In this case I restricted the turn even though its allowed 21 hours a day. My reasoning being that it's one block off a HWY, and there is a safer 24hr left hand turn with a turn lane 2 blocks up.

My next question is, should I just mark this as solved any time UR error pops there saying this turn should be aloud? or what is the best way to handle this now?

Thanks in advance,
ChunkMonkey.
