An asymmetric exclusion model with overtaking a numerical and simulation   study
  An asymmetric exclusion model on an open chain with random rates for hopping particles, where overtaking is also possible, is studied numerically and by computer simulation. The phase structure of the model and the density profiles near the high and low density coexistence line are obtained. The effect of a site impurity is also studied.
