Re:Inductive sensors (Score 1)

Nice in theory but unfortunately the sensors are not that sensitive to read a unique footprint or EM signature. Vehicle detectors come in a handful of varieties but the two most prevalant ones are electromagentic and sidefire radar. The EM sensors only reads the change in EM field as a vehicle passes through. Again, not a unique signature. With sidefire radar, all you are doing is measuring vehicle presense, speed and sometimes classification.
