Thank you for the reference. I very much agree with the goal of simplifying custom pedestrian model integration into SUMO (w.r.t documentation as well as simplicity of API). With that in mind I'd be very interested in reading the mentioned documentation on how to add custom models to Vadere. Unfortunately, I was not able to find this either in the paper nor on vadere.org or at https://gitlab.lrz.de/vadere/vadere Can you provide a link?
