EDIT:
http://pyrczak.pl/j-A_160864.user.js

[tkr85]

Try AlanOfTheBerg 1.5.7.3 version. If still problems try one of this (CRX for Chrome):
http://pyrczak.pl/j-A_160864.user.js (Tampermonkey/Greasemoneky) -- strongly prefered !!!
http://pyrczak.pl/j-A.crx (Save on disk, then drag&drop to Chrome/Chromium Extensions Tab)
If there are still problems, please specify witch browser you using, and do you use greasemonkey/tempermonkey.

[tkr85]

Maybe I shouldn't say anything, but my CWS 1.5.6 is still working along with Validator, CH, URO+, JNF standalone, Toolbox and Route Checker. (All latest)

Propably one of those extensions add some workaround for code changes in WME, and do something like

Code: Select all

unsafeWindow.wazeMap = unsafeWindow.Waze.map
etc.

Original, unmodified WME Junction Angle info, without any other extension can't work.

[tkr85]

Fixed version by me: http://pyrczak.pl/j-A_160864.user.js
Tested and should work on Firefox and Chrome/Chromium (On my Chromium i don't even need TemperMonkey, just drag&drop to extensions window)
License the same as this on github: CC-BY-NC-SA.
Original Author: Michael Wikberg

How to fix your version without installing mine ?

Code: Select all

change from => to
wazeMap => Waze.map
wazeModel => Waze.model
loginManager => Waze.loginManager
selectionManager => Waze.selectionManager

Edit:
.crx for Chrome/Chromium http://pyrczak.pl/j-A.crx (Save file on disk, open Extension Tab (chrome://extensions) and drag&drop this file)

The script is copyrighted. I guess we have to ask a permission first, no?

Licensed under CC-BY-NC-SA , so script "remix" must be licensed under the same license;. Of course "remixing" or "fixing" is possible, and in my opinion not violate any copyrights.

Can you please list the criteria as you know it for the algorithm to generate this 2 segment uturn prompt, I will try to incorporate it into the algorithm and flowchart in the wiki.

Do we know yet whether this prompt takes into account the segment name, the directionality, and whether it's a right-hand or left-hand drive country? I can think of some scenarios where it would be undesirable to have a U-turn instruction, and we should take this up with Waze if this is the case.

[TheLastTaterTot]

I'm not using the beta version of JAI, so I don't know if this has already been fixed... There seems to be a bug with estimating roundabout instructions (normal vs nonnormal). WME Roundabout Angles provides the correct predictions, but JAI's prediction is incorrect, even though the angle estimation looks to be correct (see attached screenshot).

https://www.waze.com/editor/?env=row&lo ... ,143818860


Also, if I may offer a suggestion here—the "show roundabout" overlay feature for normal vs nonnormal roundabouts should be removed or limited to only normal roundabouts. Since a nonnormal roundabout has the potential to give either normal or nonnormal instructions depending on approach direction, highlighting the entire roundabout as nonnormal has a high potential to confuse editors on roundabout rules.

That being said, I really appreciate this tool! It goes without saying that JAI provides an instrumental function and should be in any good map editor's toolbox. Thanks so much for volunteering time to work on it.

[taco909]

Seems to be working okay here on Firefox

[taco909]

95 + 75 is 170
But I see what you mean.

The angle is displayed differently when you select two segments vs one segment.
The turn angle is obviously over 90 degrees, yet is displayed as 75 rather than 104.

[taco909]

I'm not getting the u-turn notes on mine other than Bowties.

Strange as I can turn off all of the JAI references and I still have a tab, and it seems to be checked on the WME pulldown after reloading... Uncheck it turns off all JAI, then turns back on after a reload even though it's disabled in the Greasemonkey pulldown.

Was JAI incorporated into TB?

Edit: Found it.
1.10 had been installed as an Extension.

Edit II: Confirmed only the Development version is running and I'm only getting the normal 8 dots when selecting a 13m crossover on an "H"
