In Sussex we use Gatso cameras which use radar to detect vehicles driving over a speed threshold and record 2 images of the vehicle. On each image the date, time and speed is recorded we also verify the speed by measuring how many of the white marks on the road the vehicle has passed between image one and image two. Most of our cameras are now digital and send the images via the internet to the back office shortly after the offence has been detected.
Average Speed Cameras
Currently there are two permanent average speed camera systems operating in Sussex. These are located at Marina in Hastings and Marine Parade/Madeira Drive in Brighton. The cameras work by recording the time that a vehicle enters and exits the zone covered by the camera system. Each zone is calibrated so that the distance between each camera in known and using the time recorded by each camera the speed of the vehicle between the two points can be calculated
Mobile Speed Cameras
Theses cameras are mounted in the hi-viz camera vans and move from location to location. The camera operator assesses the speed of an approaching vehicle and if they believe it is exceeding the speed limit they will use the laser on the camera to verify the speed and record the date, time and speed on video.
Red Light Cameras
These cameras monitor junctions and record images of vehicles which fail to stop at red lights. The cameras are linked to the traffic signals and loops in the road which sense when vehicles drive over them.
When the images from these cameras are received by the Partnership, we can clearly see the time that the lights went amber, when they went red and when the vehicle triggered the system.
