Abstract: A system and method is proposed to ensure detection of signal light integrity and viewability. The system includes a wireless network of signal light monitors attached unobtrusively to the sun visors on each signal light for which monitoring is required. Each signal light monitor includes diverse sensors which detect signal light integrity and viewability. The detection sensors are simultaneously active to detect signal light intensity, color intensity and viewability. The information obtained from the sensors is transmitted wirelessly to a base signal light monitor. The base signal light monitor communicates this information over a mesh network to an edge processor. The network is self-healing and ensures data integrity using a pre-calculated communication link if a communication link between base signal light monitors is lost or broken. The edge processor is capable of image and condition analysis on the detection data and communicates events to an enterprise network for action.
