Steady-state control for signalized intersections modeled as switched server system

This paper proposes two kinds of signal control strategies for a multiple-phase signalized intersection modeled as the switched server system. Firstly, a class of switched server systems is introduced, and then two kinds of scheduling policies of the server, i.e., priority-based scheduling policy (PBSP) and clear-oldest-buffer scheduling policy (COBSP), are considered, under which the switched server system is periodically stable. Furthermore, the signal control for a multiple-phase signalized intersection is modeled as a switched sever system, and then the proposed PBSP and COBSP are applied to the steady-state control for the signalized intersection. At last, we illustrate our methods by the simulation for an intersection.
