• Attributes of direct measurement of inductance in a loop detector for traffic control 

      Datta, S.; Carroll, J.; V. Petit, B. Sathyamangalam, R. Hebner, M. Grady (, 2004-03)
      Inductive loop detectors for traffic control conventionally operate by sensing a resonant frequency shift when a vehicle passes over a loop. Using a digital system to measure the inductance as a function of time, better ...
    • Simulation and Field Verification of Vehicle-Loop Interactions 

      Petit, V.; Hebner, R.E.; Grady, M.; Datta, S.; Carroll, J.; Sathyamangalam, B. (, undated)
      Inductive sensors are used worldwide for traffic control. These sensors consist of a loop or loops of wire embedded in the pavement. The loops are connected to electronic control circuits that convert changes in loop ...
