FIGURE 3.

The infinite chain (N → ∞) limit nonequilibrium phase diagram of the standard TASEP. The maximal current (III), low density (I), and high density (II) phases and their corresponding steady-state currents are indicated. In this and subsequent phase diagrams, solid curves correspond to phase boundaries across which the slope of the steady-state currents (with respect to the parameters) is discontinuous. Across the dashed phase boundaries, the currents and their first derivatives are continuous.
