Hi Editors,
I’ll appreciate your help with a map update.
Permalinks:

Reason:
I was driving southbound on Lewvan Dr, requested directions to a park that was behind me, and Waze wanted me to perform an illegal u-turn. Looking into it, I believe these intersections on Lewvan Dr require junction boxes to help prevent u-turns. In Regina, u-turns are not allowed at controlled intersections unless permitted by signage. I’m a level 3 editor so I don’t have the appropriate access.
Notes:
This is my first map update request so I’m hoping I’m doing this correctly.
Thank you very much!
Looks good
Permalinks 1, 2, 4, 5, and 6 are all within the default uturn prevention mechanism (which unlike the US, we use here)
U-Turns
Waze allows U-turns at junction nodes or over a series of segments. U-turns at junction nodes are often barely possible if at all and drivers generally dislike them. The standard in Canada is to never enable the U-turn at nodes. Unlike US editing practice, this rule also applies to parking-lot roads in Canada.
Waze can recognize U-turns ove a series of segments at H or # style intersections on divided and parallel roads, like these:
Waze will recognize such a turn when all three of these conditions are met:
Three segments - The U-turn is a reversal of driving direction through three segments: an incoming segment (A), a single median/crossing segment (B), and an outgoing segment (C).Short median - The median segment (B) is less than 15.0 metres long. Note that the WME rounds decimal places to the closest integer. A segment that is 14.8 metres long and a segment that is 15.4 metres long will both appear to be 15 metres long in the WME although they will behave differently in U-turn recognition. Always adjust such median segments to 14 metres and less or 16 metres and more to trigger the U-turn behaviour you desire.Parallel segments in and out - The in and out segments (A and C) are within ±5° of parallel to each other. The sum of the angles through the U-turn must measure between 175º and 185º .
The default condition in Canada is to have the Waze routing algorithm prevent U-turns through median segments 15.0 metres (or less) long. The US allows them. The rationale for this decision is that most standard vehicles have a turn radius of 10-15 metres, making such U-turns difficult in all but perfect conditions.
Permalink 3 I did at the JB being its >15 metres
If that sounds good, please mark this thread as resolved.

If this is OK for you, please mark the thread as solved. Thank you!
