We conduct simulation study of two different models of two species driven diffusive lattice gas. These driven diffusive lattice gas models exhibit disordered phase, phase separation parallel or perpendicular to the external driving field. We study the phase transitions between these three states. The phase transitions are identified as discontinuous and continuous transitions by defining suitable order parameters. We observe a non-trivial crossover between the phase separation parallel and perpendicular to the external drive. We also discuss the relevance of these lattice gas models to the driven colloidal particles experiments and simulations.
