Dear Jakob,
I just ran my simulation with the fixed version, it works perfectly. Thanks a lot for your fast intervention and the fix!

The crash was caused by a particular road configuration and is now fixed: https://github.com/eclipse/sumo/issues/9718 KraussPS was not directly responsible for the crash but it did highlight the problem that opposite overtaking did not take slopes into account yet (now fixed:https://github.com/eclipse/sumo/issues/9719) I recommend upgrading to the latest development version which contains the fix starting tomorrow at https://sumo.dlr.de/docs/Downloads.php#sumo_-_latest_development_version regards, Jakob Am Do., 2.

I tried to reduce the complexity of the simulation as much as possible. Since it is unclear what is causing the problem, I could not reproduce the error with a smaller subset of the simulation. The KraussPS version crashes at 296 seconds.

Please provide a minimal input example for reproducing the crash. Am Mi., 1.

Therefore, I included elevation data in my network file with --heightmap.geotiff. Netconvert generates some warnings in the process, which might be related to the problem: Warning: 22 total messages of type: Connection '%' has a grade of %%. Warning: 2280 total messages of type: Edge '%' has a grade of %%. Here is my first question: Why do these warnings appear, even though --geometry.max-grade.fix is activated? Or are these warnings just generated before the edges get fixed and I can simply ignore them? However, I tried to run the simulation with these warnings. I use the "KraussPS" car-following model to include the slope impacts on acceleration. But when I run it, the simulation (and also sumo itself) crashes always at the same simulation step without any error message. (with sumo-gui as well as with sumo) If I run the same simulation with the normal "Krauss" car-following model, the simulation runs through without any problems. If I run the same simulation without elevation data, KraussPS works also fine (obviously). Any idea why this could be? I tried to understand how the KraussPS car-following works, but I did not manage to apprehend it completely, to be honest. From the comments in the code, I understand that there are mechanisms in place that prevent vehicles from stalling or drastic changes in the vehicle speed. I work with a Nightly "extra" Build of version 1.11.0 (17.11.21) on Win10. Thanks a lot for taking the time!
