SWIFT: TECHNICAL AND INSTITUTIONAL ISSUES OF AN OPERATIONAL TEST FROM A PUBLIC SECTOR PROSPECTIVE

This paper provides an overview of the Seattle Wide-area Information for Travelers (SWIFT) project. The SWIFT project delivers traffic and traveler information via FM subcarrier to hand-held wireless devices as well as in-vehicle devices. SWIFT is an unusual public/private partnership in which the public sector takes the responsibility for obtaining and formatting data for use by the private sector. Public/private partnerships are a delicate balancing act because the partners often have very different goals and motivations. In this paper, the authors discuss the technical design of the SWIFT project and examine institutional issues inherent in implementing both the technical design and the public/private sector collaboration. The hand off from the public-sector data sources to the private-sector wireless provider takes place at the communication interface where the traffic and traveler information, encoded in a standard format, is passed to Seiko's HSDS for transmission. The private sector can then obtain this information from the Seiko data stream, add value to it, and present it to the user in a way best suited to their product. The differing goals and objectives of the public and private sectors are met by defining the content and structure of messages to be passed between the participants and by defining the interfaces through which the messages are passed. The success of projects like SWIFT requires the development of methodologies like those presented here to facilitate public and private sector partnerships.
