When a vehicle crosses or stalls over the loops, it disturbs the magnetic flux and triggers the controller. Both technologies operate effectively in darkness and inclement weather where optical systems might struggle.
Highway Traffic Monitoring Sensor Systems and How They Detect Vehicles
How the Loops Detect Presence The sensor processes the change in inductance to determine the presence, position, and sometimes the classification of the vehicle. These approaches offer simpler installation in locations where cutting pavement is impractical or cost-prohibitive.
These units analyze pixel changes in the footage to identify moving objects and calculate metrics such as speed and occupancy. The accuracy of these sensors makes them essential for safety enforcement and flow optimization.
Highway Traffic Monitoring with Inductive Loop and Video Sensors
Data Integration and Smart Cities. A multi-loop sensor system creates a magnetic field that interacts with the metal components of passing vehicles.
