I also removed the Green Check from the original completed action, since the thread is now discussing further updates that need to be considered.

Alternatively, if you have brought the leaves together to a single junction to prevent the straight through movement, you can also prevent the leaf-to-leaf movement. If that is done on one of the other leaf-to-leaf junctions that should also prevent this. But I would suggest relying on the detour prevention.

Currently the Detour Prevention Mechanisms article says it will only prevent straight through routing if you have:

the last segment on the highway/freeway before the detour has the same street name and same city name as the next highway/freeway segment after the detour

In the case where a city boundary is on the overpass that crosses the freeway, we have two separate city names on the segments on either side. If the Wiki is correct you will be routed off and back on the freeway.

I propose if this is still true, we should modify this guide to provide a means to prevent this if Waze is not planning to do so.

Ideas:

1. Keep the city name the same on the freeway the same on both sides of the ramps. Won't really affect the city layer much visually at that point.
2. Remove the city name for the freeway segments on either side of the two ramps. Won't really affect the city layer much visually at that point.
3. If the city name is split at an overpass with the off and on ramp possibility, mark the straight through path as restricted. Requires we add back the image previously used.
4. Wait for Waze to do something about this (soon).

Seems like we are proposing the following change to the Wiki (at least for the USA):

1. Stop adding city names to freeways (and major/minor highways?) when not already present.
2. Remove city names from these same roadways around interchanges if the city name changes on either side.

Hazard reports will already include "near CITYNAME" without the city field populated so users are not confused as to a location.

Question: Should we review with Waze staff just to be sure there is nothing we are missing or they have never told us, or that they possibly will be doing something in the future with the city names on these roadways?

I am OK with the new proposal, but actually I believe the only reason it stopped providing the exit ramp instruction was because we showed the other route was restricted. I thought once you opened the straight through route it provided two routes from the segment exit so it would then provide both keep instructions.

I don't typically have the TTS on in my car and I am not recalling the actual TTS or text guidance that will appear in these situations. Without the "to" in the name for the continuation, what will be said if you are on "I-5 N" and the road splits between "I-5 N" and "I-505 N"?

{Red is the segment name}

If I am on I-5 N and continue on I-5 N, do I get "Stay to the left for I-5 N" ?
But if I had "to" in the name does TTS change to say "Stay to the left to I-5 N" ?

TTS will not pronounce the "to", but it will appear on-screen for the second example. You won't get an instruction though for the first example if the segment in is "I-5 N" and the segment out matches. By definition though, the first example wouldn't be a wayfinder since the segment names are the same.

Got it. My example assumed the segments and names were configured as described above me with the appropriate gaps to trigger the name change.

I know it probably falls in the category of too rare for the wiki, but here goes:
What about the Diverging Diamond Interchange (wiki), do we want to include this style?
I know Maryland just built our first last year (edit: 2012).

Aww {expletive}! I promise I really do read threads. I thought I could skip one page and be safe. I've clearly now learned my lesson.

I think this comes back to the need for a "straight" or "continue" option (wish list).
It would be so nice to hear "Continue to the Left on I-10W" or "Continue straight on I-695 E".
