As there was recently a question about modelling traffic, I found
a voluminous review paper at

In the so-called "microscopic" models of vehicular traffic,
attention is paid explicitly to each individual vehicle each of
which is represented by a "particle"; the nature of the
"interactions" among these particles is determined by the way the
vehicles influence each others' movement. Therefore, vehicular
traffic, modeled as a system of interacting "particles" driven far
from equilibrium, offers the possibility to study various
fundamental aspects of truly nonequilibrium systems which are of
current interest in statistical physics. Analytical as well as
numerical techniques of statistical physics are being used to study
these models to understand rich variety of physical phenomena
exhibited by vehicular traffic. Some of these phenomena, observed
in vehicular traffic under different circumstances, include
transitions from one dynamical phase to another, criticality and
self-organized criticality, metastability and hysteresis,
phase-segregation, etc. In this critical review, written from the
perspective of statistical physics, we explain the guiding
principles behind all the main theoretical approaches. But we
present detailed discussions on the results obtained mainly from
the so-called "particle-hopping" models, particularly emphasizing
those which have been formulated in recent years using the language
of cellular automata.
