Quanergy and Parifex have collaborated on speed enforcement using Quanergy’s 3D lidar technology for the past few years, but now the technology has become the first lidar-based speed detection system approved for use by French law enforcement.
Quanergy’s M-Series 3D lidar sensors are integrated into Parifex’s double-side VIGIE solution, which is used for highway speed monitoring and enforcement. The speed enforcement solution is fully automated and can monitor multiple lanes of traffic, and, in addition to detecting speed, can identify and classify each vehicle. It can determine which vehicles are speeding versus those that are traveling at normal rates of speed.
Last year, the two companies deployed the systems in Rouen, France, with lidar able to detect speeds at up to 200 meters with an angular resolution of 0.033° to detect speed violations even on busy highways.
The lidar-integrated solution was certified by the Laboratoire national de métrologie et d’essais (LNE), an organization under the French Ministry of the Economy and Finance. The certification paves the way for use of the lidar-integrated system by law enforcement as opposed to speed enforcement using the current Doppler system.
