Abstract
Methods and apparatus for such that a measurement made for a given vehicle by a given detector is substantially repeatable using either the same detector from one time to another, or using a different detector. In one embodiment, normalization coefficients are determined by measuring one or more common probe vehicles and standardizing the outputs of the detector(s) to give a consistent output. In another embodiment, normalization coefficients are determined by measuring one or more operating or circuit parameters of the detector circuit(s), and compensating the outputs of the detector(s) for variations in these measured parameters.
