Hi Jakob, Thanks! Anyhow, I doubt this is the main problem, as I add all vehicles via TraCI. Also, I always get the same results on the same machine, but different results on a second machine, so I would exclude the RNG as a culprit. I’m not that deep into C++ and compiler stuff, but could precision / rounding / comparison of doubles play a role and result in different behavior on different machines?

The most likely culprit in your case was the RNG that determined insertion of flows with attribute 'probability'. regards, Jakob Am Mo., 23.

On different machines we receive slightly different results in the counts of vehicles (+/-1 vehicle). Both machines uses the same version of SUMO and the same random seed. Has anyone of you experienced such behavior in the past, can give me an explanation, or has any other idea?
