This Traffic Management Center was a design-build project intended to deliver a complete, operational, traffic-responsive and coordinated traffic signal system. The project included the construction of a two‑story, 10,000-square-foot concrete Control Center building to serve as the central headquarters for traffic operations on Guam, and as the maintenance facility for the traffic signal system. The Center was equipped with the proper hardware, software, and communication systems for a fully-functional traffic signal system. A fiber optic backbone along Routes 1, 16 and 4 was utilized as the communication link between the traffic management center and the signalized intersections on those routes. A CCTV traffic signal surveillance system was installed at critical intersections to monitor and track conditions and congestion. Traffic signal timing may be adjusted remotely at the traffic management center. Preemption detectors were being provided at selected intersections as a safety measure for emergency vehicle access. Mast arms and signals had also been provided at selected intersections. Other works included modification and upgrade of existing traffic signals and installation of system (video) detectors at key locations for traffic volume and speed.
