Abstract: PURPOSE: A digital traffic signal control system is provided to reduce maintenance costs by reducing a power line for driving a signal lamp. CONSTITUTION: A region controller receives a signal operation plan from a control center and is operated in a central control mode. A detection information process unit(200) collects a detection signal from the each detector of a detecting unit. An information collection integrated device and a signal process integration device(530) is arranged in the each direction of a road and controls the traffic signal at directions of the road through wire/wireless network. A digital signal controller receives the signal process command of the region controller and drives a signal terminal device through the signal process integration device.
