Did it actually route the wrong way, or was the purple route in WME drawn the wrong way?
Not sure. I haven't seen an example since I realized the purple route might not be the actual route given in the client.

Not to mention that the minute you do that, you create a roundabout with non-sequential segment IDs, and I've read that can cause problems with navigation through a roundabout. The Toolbox will specifically flag such a roundabout as one which could cause potential problems (and if you use the "redo roundabout" tool, it will (quite properly, IMO) remove the extra node you just added because there's not actually a road attached to it).
So recreate the roundabout with the extra node. I still don't really understand the point of mapping roundabouts with only two segments. But I have seen them give similar problems as any two segments that are connected to the same two nodes. I've had more issues with two segment roundabouts than with non-sequential segment ID roundabouts.

Exactly. Even less work is just having a street with no roundabout at all.
SuperDave1426 wrote:Since when is a roundabout about how many roads enter it? A roundabout is a big honkin' (or in some cases, a small honkin' :-)) circular road, running one way, around something in the middle of it. Other roads attach to it and those coming from the entering roads are required to yield to the traffic already in the roundabout.

In U.S. dictionaries the terms "roundabout", "traffic circle" and "rotary" are synonyms. There's no requirement that there be more than two roads attached.
A couple of thoughts.
1) I didn't say they weren't roundabounts, just that they weren't worth mapping.
2) Although yielding to the traffic is a consideration, its not a universal quality of traffic circles. There are certainly urban signaled circles where "at the roundabout take the second exit" is a useful instruction, but the traffic in the circle doesn't have any right-of-way over the traffic entering the circle as the entries are all signaled.
3) I still don't see the advantage of an instruction that says "at the roundabout continue straight" or "at the roundabout take the first exit," when there are no other roads to take. The roundabout as a corner does confuse me. I prefer "take at left at . . .", to "at the roundabout take the first exit", if the only things I can do are turn left or go back the way I came. If its truly a big honkin' circle, I'd prefer to get a turn right at State Circle and then get a turn right on Main St instruction.

Is it, in fact, still the case now? Have you seen any recent occurrences of whatever the problem behavior is that you've seen? It could very well be that it's already been fixed.
I have not seen recent occurrences, so roundabouts may now be treated differently with regard to this issue.

Sure you can make the request. But if I understand correctly, the validator is simply applying the same rules regarding two segments connecting the same two junctions that is applied to any segments to roundabout segments. I do believe that there are currently problems when the same two segments connect the same two junctions. I guess I'd like to see more evidence that roundabout segments are somehow treated differently with regard to these problems.

Don't know about the Int'l server, but having two one-ways that connect the same two junctions has caused problems in my area. If the origin or destination is on one of the street waze will occasionally start or stop the route on the other. This has been solved by adding a extra junction on one of the segments.

What is the known navigation error in this situation?
How do you correct it?
I'm not sure what the problem would be on a one-way terminal loop, if any, but knowing which way to go from a dead-end isn't really a problem.
I've seen numerous reports of problems with one-way terminal loops. The problem is that waze ignores the one-way property of the road, so will appear to route either way around the loop. You correct it by putting two extra junctions in the loop.

Must seems strong to me. These segments have been ramps for quite some time and I've never found enough of a reason to change them.

It comes from the suggestion in this thread: forum post No objections, so the check is implemented.
Let me know if the check should be disabled for US.

Hmm, that's exactly what I do - put all the possible destinations shown on the road sign in ramp streetnames. If the check is useful to others that's fine. But I'm not limiting my ramp names to 65 characters.

Simply put, there is not Road Type for connectors below the class of highways (freeways, MH, mH).
(I highly favor adding a proper road type for connectors; perhaps this is what "Service road" was originally intended to do.)

For normal classification Streets (primary street, street, and the obsolete service road), any connector is the lower of the two ends.

For Other - drivable (dirt roads, parking lot roads, and so forth) and all Non-drivable types, any connector is just whatever it is.

Ramp is a highway classification in the taxonomy of Road types.
Using Ramp for a street is a misuse of a highway road type for non-highway function.
  • Highway
    • Freeway
    • Major highway
    • Minor highway
    • Ramp
    Street
    • Primary street
    • Street
    • Service road
Maybe this discussion should be split from this thread again, but I disagree with this statement. The guidance in the US, as noted above, is that ramps are to be used for grade separated connections. We could discuss changes, but "highway function" is term that we can endlessly debate. Again we should likely have that debate elsewhere.
