Abstract: The signal control system of the congestion length is described by a non-linear time-varying discrete dynamic system and synthesised by using the feedback control based on the volume balance at each signalised junction. Two signal control algorithms are presented to balance congestion lengths which cross each other on a road; one is at single signalised junction, the other along arterials. These control algorithms are such that the sum of congestion lengths along each approach is minimised by using parameter optimisation methods. The signal control system is developed systematically according to the procedure ranging from the road analysis to the simulation. From the comparison of congestion lengths between measurement values controlled by a pattern selection method and simulation values controlled by the proposed signal control algorithms, it is confirmed that the signal control system and its development procedure work effectively to control congestion lengths along an arterial in Hiroshima city, Japan.
