A dynamic system and a signal control algorithm which control congestion lengths on two-way traffic arterials are presented in this paper. The volume balance is held for each lane at each signalized intersection of arterials for a certain duration. 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 and synthesized by using feedback control. A balance control algorithm, in which the three signal control parameters consisting of the cycle length, green split and offset are searched systematically so as to minimize the sum of control errors of the signal control system, is presented. From the comparison of signal control parameters and congestion lengths between measurement values and simulation values, it is confirmed that the signal control system and the balance control algorithm work effectively to reduce the congestion lengths on the arterial.
