Abstract

This paper studies a signal control method to control congestion lengths on arterials systematically. The congestion mechanism which plays an essential role to control congestion lengths is described quantitatively based on the volume balance at each signalized intersection. The signal control system of the congestion length is described by a nonlinear time-varying discrete dynamic system. The three signal control parameters consisting of the cycle length, green split and offset are controlled systematically so as to minimize the sum of congestion lengths on arterials. From the simulation results, it is confirmed that the balance control algorithm works effectively to reduce the congestion lengths on an arterial.
