Abstract

This paper studies a signal control method which controls congestion lengths on two-way traffic arterials systematically. The signal control system of the congestion length is described by a nonlinear time-varying discrete dynamic system and synthesized by using the 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 congestion lengths on the arterial is presented. From the comparison between measurement values and simulation values, it is confirmed that the balance control algorithm works effectively to reduce the congestion lengths on the arterial
