The 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 propagation time, proximity, dead reckoning, and triangulation. The relative merits of each of these systems are discussed and, where test or simulation data and cost information are available these, too, are provided. 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 possible 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. The best available technical and cost data have been used throughout. The report is supplemented with a full list of references and a complete bibliography.
