When a vehicle crosses or stalls over the loops, it disturbs the magnetic flux and triggers the controller. When strategically placed, these systems provide rich data sets for traffic analysis and incident detection.
Adaptive Traffic Signals Sensor Integration and Detection Technology
These approaches offer simpler installation in locations where cutting pavement is impractical or cost-prohibitive. Radar and Lidar Sensors for Speed Measurement Radar sensors use radio waves that bounce off vehicles to calculate speed and distance with high accuracy.
Traffic sensors form the invisible nervous system of modern transportation, quietly collecting data that keeps cities moving. Video Detection and Computer Vision Advances in imaging technology have popularized video detection systems that replace physical loops with stationary cameras.

Inductive Loop Detectors: The Legacy Standard The most established method relies on inductive loop detectors embedded beneath the road surface. These units analyze pixel changes in the footage to identify moving objects and calculate metrics such as speed and occupancy.
