“…It is a well-known fact that a local defect can affect the low dimensional non-equilibrium systems on a global scale [30,31,32,33,34,35,36,37,38]. This has been confirmed not only for simple exclusion process but also for cellular automata models describing vehicular traffic flow [39,40]. Analogous to static defects, in our case of dynamical impurity, we observe that the effect of the site-wise dynamic defect is to form a plateau region ρ ∈ [ρ − , ρ + ] in which ∆ = ρ + − ρ − is the extension of the plateau region in the fundamental diagram.…”
