Query: Finite Size Effects in the Nagel-Schreckenberg Traffic Model   We examine the Nagel-Schreckenberg traffic model for a variety of maximum
speeds. We show that the low density limit can be described as a dilute gas of
vehicles with a repulsive core. At the transition to jamming, we observe
finite-size effects in a variety of quantities describing the flow and the
density correlations, but only if the maximum speed $V_{\text{max}}$ is larger
than a certain value. A finite-size scaling analysis of several order
parameters shows universal behavior, with scaling exponents that depend on
$V_{\text{max}}$. The jamming transition at large $V_{\text{max}}$ can be
viewed as the nucleation of jams in a background of freely flowing vehicles.
For small $V_{\text{max}}$ no such clean separation into jammed and free
vehicles is possible.
