It is a 3D radar with LiDAR sensor. It's called Nano but its eyes are huge: it has 360° vision and measures much more than just instantaneous speed: speed control, red light control, safety distance control, line crossing control white, contraflow traffic control, stop sign detection, priority on the right, pedestrian safety. Just that !
This device has been in development for six years and is called Parifex Nano, and it is much more than a radar. Thanks to the 3D LiDAR sensor it is able to reconstruct the surrounding environment through a three-dimensional scan, it operates within a radius of 100 meters and with 360° coverage.
The acronym LiDAR stands for Light Detection and Ranging, the operation is similar to radar but distances to depths are detected with a laser beam that rotates at very close intervals. At each rotation, all moving objects are modeled in 3D, the software defines them one by one and is therefore capable of measuring their movements in space and time.
It is used in many areas, in the automotive sector to provide information to driver assistance systems, but precisely the Nano was developed by the French company Parifex for road control and therefore for traffic code violations. road.
And this has just been approved in France, but for the moment only to measure speed once installed in fixed equipment. Potentially, however, not only is it capable of measuring the speed of multiple vehicles within its range (up to 250 km/h), but since it tracks and recognizes movements, it is capable of performing speed control, control red light, safety distance control, white line crossing control, contraflow traffic control, stop sign detection, priority on the right, pedestrian safety, etc.
It can also operate at night and distinguishes between different vehicles, as well as pedestrians and cyclists.
The Nano is the first LiDAR radar approved in France. It is already used in fixed double-sided radars but for the moment only to establish the type of vehicle in transit, while the speed measurement is done by the radar itself.
It can be mounted on a tripod for mobile controls and used for the other purposes mentioned previously. However, before that, it will be necessary to modify the regulations and above all to approve each of the characteristics permitted by this technology. A path that will probably take a few more years and a phase of experimentation.
