abstract = {Dynamical universality classes are distinguished by their
dynamical exponent z and unique scaling functions encoding
space-time asymmetry for, e.g., slow-relaxation modes or the
distribution of time-integrated currents. So far the
universality class of the Nagel-Schreckenberg (NaSch) model,
which is a paradigmatic model for traffic flow on highways,
was not known. Only the special case vmax=1, where the model
corresponds to the totally asymmetric simple exclusion
process, is known to belong to the superdiffusive
Kardar-Parisi-Zhang (KPZ) class with z=3/2. In this paper,
we show that the NaSch model also belongs to the KPZ class
for general maximum velocities vmax>1. Using nonlinear
fluctuating hydrodynamics theory we calculate the
nonuniversal coefficients, fixing the exact asymptotic
solutions for the dynamical structure function and the
distribution of time-integrated currents. The results of
large-scale Monte Carlo simulations match the exact
asymptotic KPZ solutions without any fitting parameter left.
Additionally, we find that nonuniversal early-time effects
or the choice of initial conditions might have a strong
impact on the numerical determination of the dynamical
exponent and therefore lead to inconclusive results. We also
show that the universality class is not changed by extending
the model to a two-lane NaSch model with lane-changing
rules.},
