RADAR, ACOUSTIC, AND MAGNETIC VEHICLE DETECTORS

THREE DIFFERENT PHYSICAL PHENOMENA ARE DISCUSSED AS APPLIED TO THE DETECTION OF ROADWAY VEHICULAR TRAFFIC. THESE DETECTORS ARE THE INPUT DATA SOURCES FOR VEHICLE- ACTUATED TRAFFIC SIGNAL LIGHT CONTROL MECHANISMS, CONTROL SYSTEMS, FREEWAY SURVEILLANCE, AND STATISTICAL ANALYSIS. RADAR DETECTORS USING MICROWAVE RADIO FREQUENCIES IN THE 2.5-10 MHZ ARE DISCUSSED WITH REGARD TO OPERATING PRINCIPLES, DESIGN CONSIDERATION, AND PRACTICAL APPLICATION. SIMILARLY, ACOUSTICAL DETECTORS OPERATING IN THE 20-KHZ RANGE AND LOW-FLUX DENSITY CHANGE MAGNETIC DETECTORS ARE DISCUSSED. A COMPARATIVE ANALYSIS IS MADE OF RADAR, ACOUSTICAL, AND MAGNETIC DETECTORS, AS WELL AS MECHANICAL, MAGNETIC, INDUCTION, AND OPTICAL DETECTORS. /AUTHOR/
