OVERVIEW OF AUTOMATIC VEHICLE MONITORING SYSTEMS

THIS REPORT IS AN OVERVIEW OF AUTOMATIC VEHICLE MONITORING (AVM) SYSTEMS WHICH AUTOMATICALLY DETERMINE AND MAKE AVAILABLE TO A CENTRAL POINT THE POSITION OF A GROUP OF VEHICLES. AVM SYSTEMS USED IN URBAN APPLICATIONS ARE BASED UPON, OR ARE VARIETIES OF, FOUR BASIC TECHNIQUES- RADIO PROGAGATION TIME, PROXIMITY, DEAD RECKONING, AND TRIANGULATION. THE RELATIVE MERITS OF EACH OF THESE SYSTEMS ARE DISCUSSED. ALSO INCLUDED IS A DISCUSSION OF SECONDARY SYSTEMS' FUNCTIONS (POLLING, COMPUTATION, TELEMETRY, ETC.) THAT MUST BE ADDRESSED BEFORE A WORKABLE SYSTEM CAN BE IMPLEMENTED. POTENTIAL APPLICATIONS FOR AVM SYSTEMS INCLUDE TRANSIT BUSES, POLICE VEHICLES, TAXI FLEETS, DELIVERY SERVICES, MAINTENANCE SERVICES, AND POSSIBLY MOVING VANS, WHICH WOULD REQUIRE INTER-CITY CAPABILITIES IN ORDER TO BE COMPLETELY RESPONSIVE. THE PAPER OPENS WITH A BRIEF DISCUSSION OF THE POTENTIAL APPLICATIONS, FOLLOWED BY A MORE DETAILED ANALYSIS OF AVM TECHNIQUES THAT HAVE BEEN DEMONSTRATED, TESTED, OR PROPOSED. TECHNICAL AND COST DATA ARE INCLUDED. AN APPENDIX SUMMARIZES THE COST DATA FOR ONE SPECIFIC AVM SYSTEM. /UMTA/
