Vehicle detection loop and loop deterioration assessment

Systems and methods for vehicle detection and assessments of loop deterioration rely on changes in inductance of a loop sensor. The conductive element of the loop sensor is modeled using one or more inductances and one or more resistances. Sets of stimuli at different frequencies are provided to the...

More Information
Summary:Systems and methods for vehicle detection and assessments of loop deterioration rely on changes in inductance of a loop sensor. The conductive element of the loop sensor is modeled using one or more inductances and one or more resistances. Sets of stimuli at different frequencies are provided to the loop sensor, and the resulting responses form the basis for vehicle detection and for an assessment whether the loop sensor has deteriorated.
