Waze preferably wouldn't direct you into a gaping canyon based on incomplete map information, and shouldn't direct you the wrong way down a one-way street. So why should it direct you into a turn that is illegal 50% of the day and 100% during rush hour?

That said, from Waze's perspective it should already be rated a less than ideal route (assuming the AI is working properly). Blocking it outright wouldn't be the worst thing and would certainly eliminate the possibility of directing the user into an illegal route.

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).therubinator wrote: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.
