1. An outdoor lighting system, comprising:
- a plurality of street lights;
a luminaire associate coupled to at least some of the street lights and comprising a plurality of luminaire associate components including;
a signal processor, a communications device, a radiation transmitter/receiver, and a plurality of mechanical devices associated with the mounting and control of the plurality of street lights;
at least one gimbal attached to the luminaire associate, the gimbal having a motorized system being operative for controlling the position of the plurality of luminaire associate components and thereby directing the radiation transmitter/receiver for the luminaire associate in a direction of at least one target area on a roadway, wherein the at least one target area is determined using inputs from a plurality of sensors; and
a controller operatively coupled to the motorized system of the luminaire associate to control movement of the gimbal;
wherein the signal processor analyzes radiation received by the transmitter/receiver from the at least one target area.

11. A method for detecting situations on a roadway comprising:
-
determining a target area on the roadway using inputs from a plurality of sensors; controlling movement of at least one gimbal contained within at least a portion of a plurality of street lights, the portion having a radiation transmitter/receiver that moves with the gimbal towards the target area; transmitting radiation from the radiation transmitter/receiver towards the target area;
receiving radiation reflected from the target area by at least one of the transmitter/receivers; andsignal processing of received radiation by a computational device within the street light containing the at least one of the transmitter/receivers. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
