Abstract
A system for providing an optical event alert signal to portable devices carried by pedestrians or vehicles, comprises: a video unit located along a thoroughfare, configured to capture sound, and video images of traffic conditions and events, analyze and recognize types of events, and transmit one or more identified event data packets over a communication link to lighting device nodes located around or along the thoroughfare; and one or more lighting device nodes located along a thoroughfare, configured to repeat and cascade event information using propagation control and decode the identified event data packets and modulate an LED array to transmit an optical event signal to portable devices carried by pedestrians and vehicles.

A system for providing an optical event alert signal to portable receivers carried by pedestrians or vehicles, comprising:
- a video unit located along a thoroughfare, configured to capture video images of traffic conditions and events, analyze and recognize types of events, and transmit one or more identified event data packets over a communication link to lighting device nodes located around or along the thoroughfare;
- and
- one or more lighting device nodes located around or along a thoroughfare, configured to decode the identified event data packets and modulate an LED array to transmit an optical event alert signal to portable receivers carried by pedestrians and vehicles.
A lighting device node for providing an optical event alert signal to portable receivers carried by pedestrians or vehicles, comprising:
- a communications unit in the lighting device node located along a thoroughfare, configured to receive one or more identified event data packets over a communication link from a video unit located along the thoroughfare, the one or more identified event data packets representing captured video images of traffic conditions and events analyzed and recognized by the video unit;
- and
- a decoder in the lighting device node, configured to decode the one or more identified event data packets and modulate an LED array to transmit an optical event alert signal to portable receivers carried by pedestrians and vehicles.
