APPLICATIONS OF GEOGRAPHIC DATABASES IN ITS OPERATIONAL TESTS

A large number of intelligent transportation systems (ITS) field operational tests (FOTs) are completed, underway, or under development in the United States. Geographic databases play fundamental and critical roles in many of these FOTs, especially for those involving traveler information systems, fleet management systems, and emergency notification systems. This paper describes the types and characteristics of various geographic databases needed for ITS, and the requirements placed upon them by different ITS applications. Specific FOT examples, such as Pathfinder in Los Angeles, California; TravTek in Orlando, Florida; TravInfo in San Francisco, California; SWIFT in Seattle, Washington; and TransCal and YATI in Northern California illustrate the database requirements for various applications, such as vehicle location and tracking, destination finding and vectoring, pathfinding, route guidance, and real-time traffic information. The consequences of database imperfections in these various applications are also discussed.
