What are the two main types of speed enforcement technologies?

The two main types of speed enforcement technologies are lidar and radar, which are widely used by law enforcement agencies to measure the speed of vehicles.

Lidar, or Light Detection and Ranging, uses laser technology to accurately measure the distance to a target, allowing for precise speed calculations. This technology is effective because it can identify individual vehicles in traffic, even at high speeds, and can operate in various weather conditions.

Radar, which stands for Radio Detection and Ranging, utilizes radio waves to detect the speed of moving objects. Radar units can track speeds over a wide area and are known for their rapid response times, allowing officers to measure speeds quickly and effectively.

Both lidar and radar offer distinct advantages in speed enforcement, including accuracy and reliability. These technologies are specifically designed for the purpose of speed measurement and have been validated through extensive use and research in law enforcement settings.
