  Driven lattice gases serve as canonical models for investigating collective
transport phenomena and properties of non-equilibrium steady states (NESS).
Here we study one-dimensional transport with nearest-neighbor interactions both
in closed bulk systems and in open channels coupled to two particle reservoirs
at the ends of the channel. For the widely employed Glauber rates we derive an
exact current-density relation in the bulk for unidirectional hopping. An
approach based on time-dependent density functional theory provides a good
description of the kinetics. For open systems, the system-reservoir couplings
are shown to have a striking influence on boundary-induced phase diagrams. The
role of particle-hole symmetry is discussed and its consequence on the topology
of the phase diagrams. It is furthermore demonstrated that systems with weak
bias can be mapped onto systems with unidirectional hopping.
