Jughandles

Since these are, for the vast majority, an at-grade connector, I think we should follow the same guidelines and just use the parent type. Like at-grade connectors and other guidelines, I do not think we should have per-state guidance on this. I'd hate to have another fractured set of rules.

[AlanOfTheBerg]

Street type is valid if the parent is a street. That's what the current at-grade connector guidance says, too. Jug handles can exist on non-highway roads.

[AlanOfTheBerg]

This may be wrong, but the Wiki claims otherwise here.

Unless something has changed recently, this is wrong. It's been discussed at length in the past and I even had a thread where folks were testing for me.

TTS says "exit" whenever the parent segment is mH, MH or Fwy and the angle of departure is as stated. The road type of the departing segment has no bearing on TTS.

[AlanOfTheBerg]

I must not be understanding what you are saying, because that's not how waze has ever worked for me.
mH, MH or Fwy splits don't say "exit" for when the angle of deflections is less than 45 degrees, they "stay to left/right at . . ." on my phone. However, if departing a mH, MH or Fwy segment with a deflection of less than 45 degrees to a PS, S or R, I do get an "exit right" instruction.

I wasn't totally clear in my description. The parent type must be greater than the child.

I had to go back to the thread I started in Dec 2011 to find your response which still matches with what you just wrote: viewtopic.php?p=122841#p122841

So:
- Fwy to MH, mH, ramp, St, PLot, etc.
- MH to mH, ramp, St, PLot, etc.
- mH to ramp, St, PLot, etc.

Will all say "exit" rather than "keep right." But if it is a split, you are correct and you do get a "keep right/left."

[AlanOfTheBerg]

Maybe this discussion needs its own thread, but I'm currently looking for examples of Fwy to MH, Fwy to mH, and MH to mH. I had thought these said "keep right" rather than "exit."

It wouldn't surprise me a lot. A little, but not a lot.

[AlanOfTheBerg]

As far as jughandles are concerned, this latest development would, to me, support keeping the ramp type, since an "exit" TTS instruction is undoubtedly more appropriate when approaching one regardless of what type of road it connects to or from.

But ramp has nothing to do with it saying exit.

[AlanOfTheBerg]

Yeah, we covered that a few posts up.

[AlanOfTheBerg]

Alan amended his theory to say any lower road type will cause an "exit" instruction but that is not correct in my experience either. A minor highway off of a major highway at a lesser angle gives me a "keep right" instruction.

The bottom line is that using ramp type has everything to do with getting an exit instruction. If you use a major highway or minor highway type for the jughandle, I do not get an exit instruction (if the main road is a freeway or highway). If you use a ramp for the jughandle, I do get an exit instruction.

It looks like "lower type" must be limited to non-Freeway and non-Highway. Streets, ramps, primary street off of a highway/freeway will give an "exit" but other freeway or highway do not?

[AlanOfTheBerg]

If the cross street is a primary street, then the standard at-grade connector rule says to use primary street for the connector, regardless of the main road type. Would that primary street fork approaching the connector say "exit right" or "keep right"?

As noted above, the "exit" rule only applies to highways and freeways.
