Hi, sorry to warm this topic up again. I’ve been looking a bit more into it again and I definitely see some improvement, but the behavior of the sublane model with 0.1 s step still leads to a frequent change in the sign of the yaw rate of vehicles. Furthermore, for some vehicles, there seem to be fluctuating decisions about lane changes, so each step they redecide and the indicators blink right and left alternating each step. Is this still considered a bug or just the nature of the sublane lane-change model? If the latter is the case, are there suggested parameter sets to damp this behavior?
Thanks a lot for your suggestions Jakob Von: Kaths, Jakob Gesendet: Freitag, 14.

Especially longer vehicles (trucks, busses) in some parts of my network seem to fishtail/swerve for no apparent reason. They perform oscillating angle changes, which makes them "wiggle" without actually changing lanes. I set the lateral resolution to 0.5, the step size to 0.1 and I'm using the SUMO 0.30.0 release. Are there any hints on how to avoid this behavior? I tried adjusting the lateral speed (to 0.1), but it doesn't help. Thanks! Jakob -- Dipl.-Ing.
