Deployment of a full intelligent transportation system (ITS), which provides all user services will take many years to evolve and may require a national ITS architecture to be developed to ensure compatibility and seamless operation. Meanwhile, several operational field tests are underway targeting various subsets of the ITS user services. A subset containing services pertaining to the delivery of traffic and traveler services information to users seems to be the most promising for early deployment. One of the operational tests targeting such services is SWIFT (Seattle Wide-area Information For Travelers). The SWIFT project started in January 1995 in the Seattle Metropolitan area with the specific goal of testing the feasibility of employing an FM subcarrier communication link to deliver information to travelers. Specifically, SWIFT utilizes an advanced 19 Kbps FM subcarrier broadcast medium for the delivery of transportation information as well as personal paging information. The SWIFT system architecture is described in this paper. SWIFT is an advanced traveler information system (ATIS), which provides the following user services: pre-trip travel information, en-route driver information, route guidance, traveler services information, ride matching and reservation, en-route transit information, and personal paging. An FM receiver module that receives, processes, and generates the data stream is attached to the user devices, where user interactions and processing occur. Three devices have been targeted for the SWIFT project: 1) a SEIKO message watch, 2) a Delco car radio, and 3) a portable personal digital assistant (PDA). The level of functionality and capability differs from one device to the other.
