I noticed that the time step size (DELTAT) is directly linked to the platoon size (DELTAN) through the reaction time (REACTION_TIME), as shown in the initialization DELTAT = REACTION_TIME * DELTAN.
I'm curious why this is modelled this way, could you clarify the rationale behind this direct linkage between time step size and platoon size?

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.
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.
