What Are Vehicle Loops?
Vehicle detection loops, often called inductive-loop traffic detectors, can detect vehicles passing or arriving at a certain point, for instance, approaching a traffic light or in motorway traffic. An insulated, electrically conducting loop is installed in the pavement. The electronics unit transmits energy into the wire loops at varying frequencies depending on the model. The inductive-loop system behaves as a tuned electrical circuit in which the loop wire and lead-in cable are the inductive elements. When a vehicle passes over the loop or is stopped within the circle, the car induces eddy currents in the wire loops, which decrease their inductance. The reduced inductance actuates the electronics unit output relay or solid-state optically isolated output, which sends a pulse to the traffic signal controller signifying the passage or presence of a vehicle. Parking structures for automobiles may use inductive loops to track traffic (occupancy) in and out or may be used by access gates or ticketing systems to detect vehicles. Every day thousands of loops are installed all across this country. Chances are, you've driven over several dozen of them on your way to work - and didn't even know it. And if you are in the business of installing these fearless, underground foot soldiers, that's precisely the way you want it: a seamless encounter for every driver, every time.
