I have to be honest I've tried literally everything I can think of here and canNOT figure this out...
[Sorry, but this is really long because I also listed all the troubleshooting steps I've already taken to save you some time]
Context: The stretch of road in question is a primary arterial between two of the islands on my map, one of which is densely populated and highly desirable with loads of tourists regularly. For context, there is no zoning anywhere ON the avenue, and only somewhat limited intersections in order to keep the traffic flowing well. I use this methodology throughout my entire city, and it works very very well to keep traffic flowing
The issue that I'm having is that out of every tourist that leaves my city on this one road, about 25% of them will STOP at one of two nodes. They also almost always turn into a different lane while they stop, blocking at least two lanes of traffic in the process. There are often multiple tourist vehicles with this issue which can completely block all three lanes of traffic!
When I click on the vehicle to see what's up, the info card alternates between "leaving the city" and "looking for parking spot, leaving the city". After doing this for a moment, about 50% of them who stopped at the first node find a path to the second, and the other 50% just de-spawn themselves. Then the majority of those who reach the second node will de-spawn after searching again for a moment, and the final remaining few (very few) do indeed eventually find a way out and just continue on. For the record, traffic de-spawning is turned off in TMPE
This phenomenon is NOT happening with residents of my city - ONLY with tourists. Only on this one road. Only at these two nodes. Only when leaving.
Steps I've taken:
-Destroy and rebuild road
-Rebuilt with different type of road
-Changed road from ground to elevated (this merely changed the node(s) where it occurs, but it still happens)
-Assured that the node/ground->elevated transitions were super smooth, level, and lanes match up in a straight line
-Moved the node(s)
-Change the node type (middle/bend/custom, etc)
-Destroy/rebuild the pedestrian path next to the road
-Added more parking near the passenger train station nearby
-Added a new outside connection (passenger harbor) on the other side of the island
-Increase/decrease speed limits on the road
-Broken Node Detector found zero broken or ghost nodes on the map
-Checked TMPE - no lane instructions on those nodes (no Hugo There ™️)
-I tried adding Hugo There lines
-Path units, vehicle counts, etc are all well below the game limits
-All mods are updated
-All mods are compatible using latest Compatibility Report
-tbh I've probably tried more things and can't remember
I've been playing with this general set of mods for a while now and have had almost no issues until I developed this island and built this road to it. It has since become an issue because not only did a LOT of people move there, but tourists like to visit the area too
Right now the traffic off the island is "meh" at best, because a ton of tourists STOP at those nodes. I'd imagine that if this were a broken/incompatible mod that it would affect all vehicles at that node, not just tourists though?
For the record, Compatibility Report did find a mod I was using that apparently causes an error with TouristAI. When I unsubscribed from that mod, the problem improved from nearly game-breaking to moderately inconvenient, but is definitely still present, and only at those specific nodes. I have played the game for quite some time since unsubbing that mod, so I highly doubt any of the current tourist vehicles already existed in-game since before then. Am I missing something obvious here? Is there something particular about tourists in the game that I just don't know?
I'm at a loss, and I really hate having clogged traffic coming off my most densely populated island!
