Lidar has a wide range of applications; one use is in traffic enforcement and in particular speed limit enforcement, has been gradually replacing radar since 2000. [1] Current devices are designed to automate the entire process of speed detection, vehicle identification, driver identification and evidentiary documentation.

Newer speed detection devices use pulsed laser light, commonly referred to as LIDAR, rather than radio waves. Radar detectors, which detect radio transmissions, are unable to detect the infrared light emitted by LIDAR guns, so a different type of device called a LIDAR detector is required. However, LIDAR detection is not nearly as effective as ...
It distinguishes pedestrians, bicyclists/motorcyclists, small cars, SUVs, pickup trucks, buses, and large semi-trucks. 2014 Speed Assist Front-facing cameras detect speed limit signs and compare them against map data to display those limits on the dashboard center display even if no signs are detected.
