[Page Update] Intersections / U-turns under 15m

After a discussion with Driving79 there was some initial confusion regarding an UR that stated no U-turns were allowed. She originally resolved the initial issue but then the requester had a subsequent update request which I then made what I believed to be the appropriate changes. After discussing the issue with her, we found that technically either solution would have worked. However, my justification for the changes I made
Reason being for the bowtie, it shows an actual turn restriction for the No U-turn in the editor should any future editors come look at this intersection where they might see your solution with a segment with turns allowed while under 14 but does not know the 14m rule which would likely result in confusion. Plus, for PA, I try to keep everything as defined in the the wiki, which as per the wiki which does not directly mention the 15m rule, I believe a bow tie would be the solution here even though yours would work as well.
Essentially, we found that the intersections wiki does not directly link or tie in any information on the 15m rule. Can you please create/incorporate Routing_penalties#Road_configurations into Junction_Style_Guide/Intersections Wiki to eliminate potential confusion in the future.

Sounds ok

Again, if the junction box isn't a mirage permanently on the horizon, then I'm not worrying too much about bowties and odd internal bars on U-turns. All this should eventually become moot.

Sure. I'm just noting why I'm not putting much time into to perfecting the explanation.

Seems worthwhile to document the current statement of the U-turn prevention, if only to clarify what example can be used to show its not working as we've been told.

Many U turns that were working in the past, that were set to 15 meters, have stopped working. When distance was increased to 16 meters it started working again.

I have reported this in several places, but had no official feedback.
What PesachZ said is correct. If you have WME Toolbox ruler enabled, try to check the actual length of the u-turn segment in decimal. A length of 14.5m - 15.4 m is considered to be a 15m segment in WME, so if the actual length is less than 15.0 m, then the u-turn will be prevented.

Awesome job to all involved, and especially with the illustrations! It will be a welcomed update.

Great job! I'm a very visual person so representations like these make understanding the content much easier.

a group of editors have been working on a revised version of this section of the wiki with the goals of clarifying, simplifying and updating its contents using all-new supportive illustrations. The content also includes some changes in the actual behavior of the penalty based on user experience, testing, and reevaluation of the original statements made by the staff so that the guidance is now more precise.
The new draft content is currently in my user space pending review and approval here. Please provide constructive feedback. If there are no objections, I'd like to publish the draft next week. The idea is to publish it as a new nugget subpage of routing penalties, and then transcluded back into this section of the JSG. However to keep the JSG page simple and not too long, the final section (i.e, Additional examples) will not be included into the JSG, there will be a link provided for more info going back to the penalties page.

Awesome work! This is by far the best explanation I've ever seen for the U-Turn prevention mechanism and the graphic explanation is also great.

Thanks
