ELECTROMAGNETIC LOOP VEHICLE DETECTORS

THREE DIFFERENT ELECTROMAGNETIC LOOP VEHICLE DETECTOR DESIGNS ARE DESCRIBED: SELF-TUNING, BRIDGE BALANCE, AND PHAZE-SHIFT. PRINCIPLES OF OPERATION, DESIGN LIMITATIONS, AND DESIGN TRADEOFFS FOR EACH METHOD ARE PRESENTED IN DETAIL. THE CHARACTERISTICS OF THE LEAD-IN WIRE USED ARE SHOWN TO BE THE PRIMARY LIMITATION IN LOOP DETECTOR PERFORMANCE AND STABILITY. CHARACTERISTICS OF COMMERCIALLY AVAILABLE WIRE USED IN PRESENT-DAY LOOP DETECTOR INSTALLATIONS ARE DISCUSSED. DESIGN EQUATIONS AND GRAPHS ILLUSTRATE THE TRADEOFF CONSIDERATIONS IN THE DETERMINATION OF OPTIMUM LOOP CONFIGURATION AND INDUCTANCE. /AUTHOR/
