Abstract :
This paper describes the current status of the ITS archived data user service for the Portland, Oregon metropolitan area. Included is a discussion of the definitions, benefits and history of ITS data archiving. Case studies of three current ITS data archiving projects are also presented. The requirements and characteristics of a long-term data archive for ITS data are summarized and the implementation plan for this service is presented. Design features of preexisting data archives and guiding principles are described. Design choices made in response to these principles are discussed. The final database design is then outlined.
