Which technology is more effective for measuring speed?

LIDAR is considered more effective for measuring speed primarily because it operates with a higher level of precision than RADAR. LIDAR systems use laser beams to measure the time it takes for a light pulse to bounce back from an object, which allows for extremely accurate distance measurements and speed calculations. This high resolution enables LIDAR to detect and measure the speed of smaller and more specific objects, making it particularly advantageous in scenarios requiring accurate speed detection, such as in traffic enforcement.

The precision of LIDAR also means that it can differentiate between multiple objects in close proximity, which is beneficial for speed measurement in congested areas. This capability makes it an ideal choice for applications where accuracy is paramount, as it minimizes the risk of inaccuracies caused by reflections or environmental factors that might affect other technologies.

In contrast, while RADAR typically has a broader coverage area and can effectively detect larger objects, its speed measurement may not be as precise due to factors such as signal dispersion and interference from surrounding objects. This is why LIDAR is often favored in scenarios where precision speed measurement is essential.
