Abstract
Systems and techniques are described for a signal head processing system. A signal head detector can be mounted by or attached to an existing control light signal head and provide data indicating the state, i.e., on, off, blinking, of each light of the control light signal head. The signal head detector can communicate with a nearby gateway device. The gateway device, in turn, communicates with a back end server, and the back end server performs near real-time control light pattern analysis and provides near real-time light status. Alternatively, the signal head detector can communication directly with the based end server. The server analysis can include frequency of light change per canister, intersection geometry and lane flows, per-intersection control lighting patterns, seasonal, e.g., time of day, lighting patterns, anomaly detection and failure detection.
