Question: direct link between time step size and platoon size about uxsim HOT 2 CLOSED

There is a theoretical reason. In this way, we can compute the exact solution of KW model (the underlying traffic flow model of UXsim) efficiently. In short, it eliminates numerical errors. If we use different setting, it will induce so-called numerical diffusion or instability.

If you want know the details, you need to read a paper: http://www.sciencedirect.com/science/article/pii/S0191261513000349

Thanks!

By the way, it might be useful if the Discussions tab could be enabled on this repository. Then users would have a place to discuss questions, configurations and new ideas, without adding noise here in the issues.
