A REPORT ON INDUCTIVE LOOP TRAFFIC DETECTION UTILIZING A COMMON SLOT

THE OBJECT OF THIS TESTS WAS TO CONDUCT A CONTROLLED TRAFFIC COUNT AT AN INDUCTIVE LOOP LOCATION TO DETERMINE IF INTERACTION WAS OCCURRING WHEN USING A COMMON SLOT FOR THE LEAD WIRES AND LOOPS. THE COMMON SLOT FOR LEAD WIRES AND LOOP WIRES WAS USED BECAUSE OF THE FEELING THAT A 2-FOOT OFFSET BETWEEN LEAD WIRE SLOTS AND LOOP SLOTS INCREASES THE POSSIBILITY OF CONCRETE PAVEMENT SPALLING. INTERACTION RESULTING IN EXTRA COUNTS WAS NOT OBSERVED ON THIS COMMON SLOT INSTALLATION DURING THE TEST. AN OVERALL SYSTEM ERROR NOTED FOR A FOUR HOUR COUNT WAS &2.2% THAT COMPARES FAVORABLY WITH SYSTEMS NOT HAVING A COMMON SLOT. /BPR/
