This paper studies the adaptive traffic congestion control of traffic network from the system-theoretic view-point. The time-dependent characteristics of traffic congestion length are described by a linear time-varying discrete dynamical system based on the traffic volume balance at each signalized intersection. We propose the adpative control system of the traffic congestion length in a traffic network using a decentralized control concept. We also propose two adaptive control algorithms for traffic congestion length control in a traffic network; one is a 'priority control algorithm', the other is a 'balance control algorithm'. The Simulation of two adaptive control algorithms confirms that the cycle lengths, green time and offsets are adaptively controlled according to the variation of incoming traffic volumes, and the priority and balance control algorithms work well to control the traffic congestion lengths at two-adjacent signalized intersections.
