Loop Vehicle Detector

Inductive Loop Activation:

• When a vehicle drives over the loop, its metal mass causes a change in the inductance of the loop (the magnetic field around the loop changes).
• This change is detected by the loop detector, which sends a signal to the traffic signal controller.

Vehicle Detection:

• The system detects the vehicle's presence based on the changes in the magnetic field. The detector can determine whether a vehicle is stationary or moving.

Action Trigger:

• The system can trigger actions like turning a traffic light red or green, depending on the presence of vehicles in the detected area (e.g., for waiting cars to be prioritized at traffic signals).
