Abstract
 
We use a computer-based cellular automaton to study two-component flow,
mimicking (fast) passenger and (slow) cargo vehicles, on a circular
unidirectional two-lane highway without on-ramps and exits. The global
flow rates for different overall densities and mixing ratios between fast
and slow cars are determined. We study two main scenarios: two-component
traffic without passing restriction (uncontrolled flow) and traffic in
which slow vehicles are prohibited to pass (controlled flow). We find that
controlling the flow should considerably increase multi-lane highway
capacity.
