Abstract: A variety of vehicle location and tracking technologies are under consideration for such IVHS applications as Automatic Vehicle Location (AVL), Computer Aided Dispatch (CAD), and vehicle navigation and routing. The technologies being considered include dead reckoning, map matching, global positioning sateliltes (GPS), radiotransponders, direction finding, Loran, Cellular phone tracking, electronic benchmarks, etc, or various combinations of these techniques. This paper will describe the most promising vehicle location and digital map technologies. Their relative and absolute accuracies, and their suitability for various IVHS applications.
