As you may have guessed, this kind of detector works by detecting an inductance change in a wire loop (aka coil) buried in the road. Having a car pass several inches on top of it produces such an ...

and an extensive amount of documentation is available on this if you want to try to roll out your own inductive loop vehicle detector. Of course, this isn’t the only way to detect a vehicle’s ...

Basically it's an above-ground version of the in-pavement loop detection system we also use at other intersections to detect vehicles stopped at a light. "The white box is a radar technology ...

The PD130 inductive loop detector is the most critical component of the whole vehicle access control system. Single channel loop detectors are used to identify the presence of vehicles by means of an ...

NASCAR uses transponders, timing loops, high-speed cameras, and GPS to ensure precise, split-second accuracy in every race ...
