โฆ Synopsis
We introduce a simple lattice-based exclusion model which can be considered as a crude representation of traffic on a two-lane motorway. The model is a two-lane generalization of the asymmetric simple exclusion process which is known to reproduce some of the features of single-lane traffic such as shocks and jams. A mean-field analysis for the steady state of the pure two-lane system is supported by Monte Carlo simulations. We then discuss the effect of quenched bond disorder on the current-density relation and draw comparisons with the disordered single-lane case.

More investigated situations in the field of traffic modelling are those of traffic bottlenecks caused by slow vehicles or road defects. The new aspect of this paper is the simulation of vehicular dynamics near a partial reduction in a road from two lanes to one lane. In order to reduce the bad impa
