URBAN FIELD TESTS OF FOUR ELECTRONIC VEHICLE LOCATION TECHNIQUES

FOUR ELECTRONIC VEHICLE LOCATION TECHNIQUES HAVE BEEN TESTED IN PHILADELPHIA. THE TESTS WERE PERFORMED IN ORDER TO MEASURE THE ACCURACY AND COVERAGE CAPABILITIES OF EACH TECHNIQUE UNDER REALISTIC CONDITIONS. THE TESTS INDICATE THAT MICROWAVE PROXIMITY TECHNIQUES CAN BE USED TO ACHIEVE ACCURACIES OF ABOUT 330 FEET WITH 95 PERCENT CONFIDENCE. THE MEASURED ACCURACIES OF LORAN C AND NARROWBAND PHASE MULTILATERATION ARE ON THE ORDER OF 1100 TO 2000 FEET WITH 95 PERCENT CONFIDENCE DEPENDING ON THE VEHICLE'S ENVIRONMENT. WIDEBAND PHASE MULTILATERATION, WHICH ACHIEVED ACCURACIES OF 2800 TO 5000 FEET, SHOWED NO SIGNIFICANT ADVANTAGE OVER THE NARROWBAND PHASE TECHNIQUE. A GLOSSARY IS INCLUDED.
