Major roads and arterials in the City of Tucson and Pima County are already significantly detectorized with inductive loop detectors and, at places, with video-based detectors. These detectors are used for semi-actuated signal control and for limited traveler information. In addition, many intersections have systems that allow signal preemption by emergency services such as fire and ambulance. ATLAS II projects integrate real-time data from available detectors for (a) traffic adaptive signal control, (b) providing real-time traffic predictions to traveler information systems, (c) for adaptive signal priority for transit vehicles, and (d) for proactive coordination of signal phasing to provide preemptive pathways for emergency vehicles.
