Abstract:
A method and system that relies on visibility detectors deployed on luminaires in outdoor lighting networks (OLNs) to independently treat and consolidate the sensed data in a fault-tolerant manner. By communicating with neighboring luminaires and/or with a centralized server, the invention is able to identify the position and direction of movement of areas of reduced visibility (e.g. fog). This information can then be used to alert drivers who are approaching the identified area.
