ABSTRACT:
A detector system filters the effects of periodic noise such as magnetic flux from nearby power lines or other periodic sources. The detector system further adapts in the case that the system incorporates microloops for the inductive sensors. The detector system further counts multiple vehicles while in presence mode. The detector system also logging of vehicle data and system faults.
