Abstract
The roundabout in a one-dimensional system is studied employing the synchronous totally asymmetric simple exclusion process. At special sites far from boundaries, particles can attach to and detach from the system irreversibly with respective probabilities p and q. When the system is in a steady station, seven stationary phases are possible. The results of simulations agree well with analytical calculations. The stable state of the low-density/maximal-current/high-density phase corresponds to a critical point and may transfer to six other phases.
