What is a key feature of LIDAR in speed measurement?

• A. Ruggedness for outdoor use
• B. Ability to store multiple readings
• C. Side alignment capability
• D. Integration with GPS

Answer: (C)

The key feature of LIDAR in speed measurement is its side alignment capability. LIDAR systems utilize laser technology that allows for precise distance measurements, which enables the operator to align the device at an angle to the moving target. This capability is especially useful in traffic enforcement as it allows officers to accurately measure the speed of vehicles from the side of the roadway rather than having to be directly behind them. Utilizing side alignment helps in reducing the risk of being detected by the speeding vehicle and provides a greater range of positions from which measurements can be effectively taken. The other options, while relevant to various devices, do not define the specific advantages of LIDAR in the context of speed measurement as distinctly. Ruggedness for outdoor use is a benefit that can apply to many types of speed measurement devices, not just LIDAR. The ability to store multiple readings is also a common feature in a variety of speed measurement technologies, which may not be exclusive to LIDAR. Similarly, while integration with GPS can be beneficial for providing location data, it is not a primary distinguishing feature of LIDAR systems in speed measurement, which are primarily defined by their laser-based measurement capabilities.
