Hello,

I am working on a scenario of taxi, pt, car, and bike. However at the end of last iteration, everytime I get an error saying that the output events could not be written and the simulation crashes. The error and the configuration file I use are given below.

ERROR MESSAGE

Re: Events not getting written at the end of last iteration

by Kai Nagel on 2018-05-17 17:19:12

The normal reason is that lastIteration is not a multiple of writeEventsInterval. So if lastIteration is 5, then writeEventsInterval needs to be 1 or 5.

I don't think that this error message will influence the results. But you will also not have an events file in ITERS/it.5/... .
