wrong lane usage

[failsafe]

Hi,

I have case like this below:
https://steamcommunity.com/sharedfiles/filedetails/?id=2888250232

Left lane is for left turn only, right lane is for right and forward. Dont know why but cars form long line on left lane and they try to use only left lane. From left lane they go straight, left and even right. I've checked whether there is any missing node but they have nearby node, so no problem in changing the lane. I have no idea why this happens.

Looks like lane forcing to me. Perhaps something amiss up ahead at the next intersection or so.

I have noticed that right turning traffic (right lane traffic) regardless of road markings is usually a right turn only. The next lane beside is for through traffic. Even if it is to make a right turn at the next intersection. In that case that vehicle will lane change into the right lane at the intersection. I'm am not sure if that's panic behaviour or new rules being applied.
In your case you have two lanes forward and one of them is not being represented at the intersection for some reason.

I've changed how the lanes work in TMPE. It used to be like you say: two lines ahead. But I've noticed problem with huuuge traffic on left lane and almost no traffic on right lane - this is why I used TMPE to select left lane for left and right for right/ahead. So... as you can see it didnt work. I've looked into nearby roads, I dont see anything that could cause this issue. I've been doing things like this before. Maybe if not the monorail I would use 3+3 road instead, but it has to be 2+2 here.

TMPE has own line forcing (the thing with colour markers) - I havent used it so far because I thought that there must be a reason for this situation and thought that it would be better to solve the very reason instead of just pumping more and more TMPE. But so far I see no reason.

Any chance you can reduce traffic using that lane by adding an additional way for traffic to get to wherever they want to go (by turning left on this intersection)?

Perhaps make a screenshot of a larger area around this intersection.

I don't think the monorail roads come in 6lanes. perhaps going forward from the intersection use a two lane monorail road for a tiny length. So the intersection is not confused or running double rules.

All this road is 2+2 monorail. I said I would like to use 3+3 if not the need to use monorail. In this case it has to be monorail, so I need to stick to 2+2.

Anyway, I've checked everything around. I didnt find any reason for this to happen. So... I've forced by using "colour marker" from TMPE lane usage. IT worked, though problem has been solved without finding the reason.

Traffic itself is not a problem. I have 80%+ in the city and while usage of single lane on this intersection locally ruins the traffic at the end of the day it is still okay. I've created the thread to ask for reasons why such a thing happens.

Have you tried using the Routes Overlay (The one that looks like 2 blue arrows in the overlays list) and clicking on that section of street to see where everyone is headed?

Its possible they are all using that lane because they are all headed in the same direction. Default Game (and even with TMPE if you don't change the right settings) generally doesn't randomly change lanes or consider "time savings" in their route calculations. So if their future trip requires them to make a left turn then they have a strong tendency to just stay in the left lane.

I think I usually turn on the advanced AI in TMPE and set it for something like 20% random lane change + allow lane change in intersections if going straight. That usually causes the long columns of traffic to split out across multiple lanes if they are on a longer trip.

Dono what would cause the odd "right turn from the left lane" issue as I have seen that. But not on simple road types that your using. I see it more often on the complex roads buss lines because adherence to "no cars in bus/tram lanes" doesn't always translate well :P

In TMPE there are quite afew settings that could cause conflicts like this, so it is hard to pinpoint without looking at your TMPE settings pages ..
What you could try, is to use the lane connection tool in TMPE to physically connect the left turn lane with the acceptable destination routes. This will over-ride the lane arrow only rules.

Is the traffic coming from down the road? I'm asking because I have an intersection in my current city that has tram tracks in the middle, and the pedestrians are using the crosswalk to get to the center, and then pull out their pocket car and drive off once the light turns green. The pedestrians will go in whatever direction they want to instead of where the lane arrow says to go.

Yes, I've checked this. All routes were glued to left lane and vehicles ignored right lane. I typically adjust AI settings, though I didnt do that now.

Anyway, funny thing is that it happened only here - all other roads in the city work fine.

Actually this happened before I started fine-tuning with TMPE. And my setting in TMPE are just standard, maybe except AI (though, I dont remember what is the setting for this city).

And yes, I did just that - connected physically lanes and it solved the problem, but I wanted to find the reason for this situation.

Didnt have this situation. You say... they take cars from pockests in the middle of roads? Lol ;-P.

It's funny, yes, the Cims carry around their "Pocket cars", just pop them out and drive off from anywhere.

But to the problem, I think maybe look at the intersection after the left-turn, and see where the Cims are traveling past the left-turn .. Cims will ignore arrows if it does not match their desired path, but can not ignore connected lanes .. connecting the lanes confirmed they want to go someplace they can not go by turning left, because of a conflict farther along their path, maybe another lane arrow or a connected lane one or two intersections away.

[failsafe]

no, there are no conflicts. Or at least I couldnt find any. But okay, seem to me there must be a small details somewhere that spoils everything.

What's the strange stuff happening on the top side of the junction? Why the road width changes like that after crossing? Is there 2 nodes too closely together, messing the junction up?

[failsafe]

I didnt notice this... But yeah, you might be right, something strange is there. The road is 2+2 monorail on full lenght, so nothing should change. I will check this.
