All traffic light intersections in Gainesville are equipped with underground sensors, called inductive loop sensors, that detect metal content in vehicles.

An inductive-loop sensor uses a loop of wire embedded in the pavement of each lane at an intersection to detect vehicles. When a vehicle passes above the loop, it activates a sensor, which sends a ...

Many traffic lights use inductive loop sensors, an electromagnetic detection system buried under the asphalt that detects vechicles and triggers the signal from red to green.

It's designed to make those sensors think that your bike is a car. Embedded "inductive loop" traffic sensors work by creating an electromagnetic field in the surface layer of the road.

The most common traffic light detection system is the inductive loop sensor, which uses coils of wire under the pavement to detect vehicles entering its magnetic field (they do not operate by weight).

The use of so-called traffic tech and an array of urban sensors that collect data in public places can also heighten concerns about risks to personal privacy and data security, not to mention unwanted ...

A: According to Dennis Thompson, a traffic engineer with the City of Huntsville, weight does not trip the signals. He explained that an inductive loop has been the standard form of signal ...
