The appropriate range setting on RADAR primarily depends on vehicle bunching. When multiple vehicles are traveling in close proximity to one another, the RADAR operator needs to adjust the range setting to accurately capture the speed of individual vehicles within that group. This ensures that the RADAR can precisely differentiate between vehicles that may be close in speed and distance, which is crucial for accurate measurements.

The setting helps prevent issues like echo interference, where the signals bounce off multiple vehicles, leading to inaccurate speed readings. By properly adjusting the range, the operator can focus on the specific vehicles of interest and obtain reliable data. Factors such as weather conditions, time of day, and operator experience play important roles in RADAR operation; however, they do not primarily dictate the range setting as vehicle bunching does. Vehicle density is the key factor that influences how far out the RADAR needs to sense to ensure effective and accurate readings.
