ISA was born in France when Saad and Malaterre (1982) carried out their study of driver behaviour with an in-car speed limiter. Actually, they did not really test Intelligent Speed Adaptation, because the system did not automatically set the correct speed limit; instead drivers had to set the limiter themselves, and, rather like a cruise control, they could set it as they chose.
A mobile speed camera is speed limit enforcement device used in Australia, France, India, Ireland, and the United Kingdom [1] to refer to a road vehicle fitted with speed camera equipment which can park at the side of the road, or on overbridges to monitor the speed of passing traffic. Mobile speed cameras come in many shapes, sizes and colour ...
The speed of a vehicle occluded by (hidden behind) another vehicle cannot be measured. This occlusion issue does not apply to fixed speed enforcement devices that can be mounted on poles or gantries up to 5-6 meters / 15 -20 ft high using radar as detection method. Fixed and handheld lidar systems reliable up to heights of roughly 2 meters / 7 ft.
Traffic-sign recognition first appeared, in the form of speed limit sign recognition, in 2008 for the 2009 Vauxhall Insignia. [1] Later in 2009 they appeared on the new BMW 7 Series, and the following year on the Mercedes-Benz S-Class. At that time, these systems only detected the round speed limit signs found all across Europe (e.g. [2]).
In slow-moving traffic, or when the camera is at a lower level and the vehicle is at an angle approaching the camera, the shutter speed does not need to be so fast. Shutter speeds of 1 ⁄ 500 of a second can cope with traffic moving up to 65 km/h (40 mph) and 1 ⁄ 250 of a second up to 8 km/h (5 mph).
