Abstract We present two different approaches to minimize total delay in signalized fixed-time controlled inner city traffic networks. Firstly, we develop a time discrete model where all calculations are done pathwise and vehicles move on ``time trajectories'' on their routes. Secondly, an idea by Gartner, Little, and Gabbay is extended to a continuous, linkwise operating model using ``Link Performance Functions'' to determine delays. Both models are formulated as mixed-integer linear programs and are compared and evaluated by PTV AG's simulation tool VISSIM 3.70.
