A control system for a lighting fixture (20A-20P) within a lighting fixture network, wherein each of the lighting fixture nodes includes: a controller having a light source communication output; a motion detector in electrical communication with said controller; a data transmitter in electrical communication with said controller; and a data receiver in electrical communication with said controller; said motion detector operable to detect an object within a lighting fixture coverage range; said data receiver operable to receive lighting fixture identification data from at least one of a plurality of lighting fixtures (20A-20P), said lighting fixture identification data indicative of object detection by a specific of said lighting fixtures; said controller operable to be initially dynamically calibrated during periods of low activity, wherein said period of low activity corresponds to times when relatively few cars are present proximal the lighting fixture such that the amount of time it takes for a single vehicle to travel between street lighting fixtures within said lighting fixture network and the street lighting fixture may be determined; wherein said controller is calibrated, wherein said calibration is directed to determining the lighting fixture's relationship to a plurality of other lighting fixtures within said lighting fixture network, by dynamically determining a temporal relationship to each of a plurality of said lighting fixtures (20A-20P) through analysis of a plurality of time differences for each of said lighting fixtures (20A-20P), each of said time differences related to the difference in time between a recent object detection by said motion detector and a recent receipt of said lighting fixture identification data from one of said lighting fixtures (20A-20P), wherein said temporal relationship is determined by averaging a plurality of the time differences for each of the plurality of the lighting fixtures to create a time difference average for each of a plurality of the lighting fixtures, and wherein said controller is arranged to adjust a light output of the lighting fixture based on the determined temporal relationship to a lighting fixture corresponding to received lighting fixture identification data. a controller having a light source communication output; a motion detector in electrical communication with said controller; a data transmitter in electrical communication with said controller; and a data receiver in electrical communication with said controller; said motion detector operable to detect an object within a lighting fixture coverage range; said data receiver operable to receive lighting fixture identification data from at least one of a plurality of lighting fixtures (20A-20P), said lighting fixture identification data indicative of object detection by a specific of said lighting fixtures; said controller operable to be initially dynamically calibrated during periods of low activity, wherein said period of low activity corresponds to times when relatively few cars are present proximal the lighting fixture such that the amount of time it takes for a single vehicle to travel between street lighting fixtures within said lighting fixture network and the street lighting fixture may be determined; wherein said controller is calibrated, wherein said calibration is directed to determining the lighting fixture's relationship to a plurality of other lighting fixtures within said lighting fixture network, by dynamically determining a temporal relationship to each of a plurality of said lighting fixtures (20A-20P) through analysis of a plurality of time differences for each of said lighting fixtures (20A-20P), each of said time differences related to the difference in time between a recent object detection by said motion detector and a recent receipt of said lighting fixture identification data from one of said lighting fixtures (20A-20P), wherein said temporal relationship is determined by averaging a plurality of the time differences for each of the plurality of the lighting fixtures to create a time difference average for each of a plurality of the lighting fixtures, and wherein said controller is arranged to adjust a light output of the lighting fixture based on the determined temporal relationship to a lighting fixture corresponding to received lighting fixture identification data.
