The optimal discretized timing plan for individual oversaturated intersections

The topic of traffic control for individual intersections has been studied for many years. A lot of work has been devoted to designing signal timing plans able to make things better under oversaturated situations. In this paper, we discuss how to discretize Gazis two-stage control strategy that had been introduced in [1] for a single oversaturated intersection. We give an optimal discrete timing plan and prove that it gives the least delay.
