The SunCam offers an alternative to embedded magnetic loop detectors. It provides data such as queue length and static occupancy enabling better evaluation of traffic demand (queue) and infrastructure availability (spatial occupancy) at intersections. This advanced data, when associated with an adaptive real-time strategy, enables incremental adjustments to traffic signal timings based on real time traffic changes at each intersection.
