It's always been common practice to reduce H-type intersection lengths to avoid u-turns. As far as I know 15m is only confirmed for NA server. For ROTW server it has to be 10m, unless this changed recently.


Maybe it's country-related. In Germany, we have just found two cases where 13m were not enough.

Best regards,

For Latvia (INTL) we need segment to be about 17m for U-turn to work. So it would be great to highlight short segments, or even allow to input length under which it needs to be highlighted.

The support section for Penalties discusses sharp angled turns comprising of 3 segments.

Well, it's a standard H-shape (one two-way street crossing a split two one-way street): https://www.waze.com/editor/?zoom=7&lat ... TT&env=usa

So U turns will only be prevented where the segment is also useful as a left turn? That's interesting. I wasn't aware of the specific mechanics of the function. I like that.

I've had to widen a number of intersection segments to 15m to allow U-turns, and shorten some to 14m to disallow U-turns. 15m has definitely been the cutoff for me based on direct experience with making the changes and testing the results after a tile update.

The editor rounds the numbers, so when it says a segment is 15m it may actually be slightly less, and will actually prevent U-turn. If you want to be absolutely sure, make the segment 16m or more to allow, and 14m or less to prevent.

With the 11m segment allowing the U-turn, there may be some geometry issues. There may be no "straight" path out of the short segment, in which case any path out of it can be used for routing.

This is weird. I have done a few u-turn length at 10m and it works.

Edit:
This is one of the U-turn that is 10m in length that is working for me.

At 10m, one had might as well use an ugly bow-tie...
