Intersection deadlock with busses/trams with crossing paths

[xenon5]

Hello, this is a problem I've observed a few times so I wanted to post about it. When two vehicles want to turn at the same time but their turns conflict with each other, the game cannot decide which should turn first and both vehicles get stuck forever. There needs to be some kind of logic implemented for who goes first in these situations.

Here's a screenshot of an example:

The tram and the bus want to turn opposite directions when next to each other at the same time, and the game cannot decide who goes first, so nobody does

The priority should of course be metro->tram->trolley->bus, and if they're both the same type then randomly pick one.

The problem on your screenshot is, that the bus needs to "teleport" to the 2nd lane to make a left turn. It's a stupid mechanism that CiM2 has from the beginning - if the bus has a stop on the rightmost lane, and then wants to turn left (and the road is 2+ lanes in one direction), it teleports to the left and then makes the turn. Here it's impossible because of the tram, and the tram is actually waiting for the bus - there we go, a neverending loop.

I seemed to run into this all the time. It was instinctive for me to place stops from different lines close to each other, but I was eternally having to re-arrange junctions when they just froze up like that.

Now I make the cims walk a bit and keep stops well apart. That makes the problem seem to go away.

Personally, I'd call this a bug

Easiest way to fix it is to send the offending vehicle to another depot.

If you need to, you can then transfer it back...
