Abstract: A lighting system for illuminating an environment, the lighting system comprising a plurality of lighting modules (111, 112, 113), the lighting modules comprising a light source (111a) for emitting light, illuminating an area, an acoustic sensor (111b) arranged for sensing noise in the area, a network interface configured to allow the lighting module to send noise data via a network, and a vehicle routing device (120) comprising: a first network interface (121) configured to receive noise data from the plurality of lighting modules via the network, a processor circuit arranged to calculate noise metrics for different regions (341-344) in the environment from the received noise data, compare the calculated noise metric with noise metric threshold values, dependent upon the calculated noise metric exceeding a noise metric threshold value for a particular region, generating a traffic rerouting signal, said traffic rerouting signal causing a traffic routing system to reroute traffic away from said particular regi

Abstract: A lighting system has at least one luminaire (1) for illuminating a thoroughfare (10). At least one sensor (11,12,13) detects that a fallen object (30) may be at least partially blocking said thoroughfare (10). A traffic flow monitor (11,12,13) monitors traffic flow along said thoroughfare (10). The light output by the luminaire (1) is controlled to be of a first pattern in accordance with a determination that a fallen object (30) is at least partially blocking said thoroughfare (10). The light output by the luminaire (1) is controlled to be of a second pattern in accordance with the traffic flow monitor (11,12,13) determining that traffic is flowing along said thoroughfare (10).

Abstract: A global object detection system comprising a plurality of local object detection systems, each arranged to monitor a respective area and comprising: an image capture device arranged to capture image data from its respective area; an illumination device for emitting light into its respective area; a local object detector for detecting objects in that area; a data interface for transmitting data from the local object detector to a central, remote image processing system; wherein the local object detector is configured to: control the illumination source to emit light having an identifiable characteristic; apply local image processing to the captured image data to detect objects in that area, as an absence of the identifiable characteristic in a shadow region created by the object; in response to an object being detected, transmit a portion of the image data including the detected object to the remote image processing system for further processing.
