The goal of this project was to help commuters make more efficient use of Puget Sound-area freeways by providing them with accurate information about traffic conditions. On-road surveys of Puget Sound commuters and other data provided the basis for the first Traffic Reporter design and prototype. Useability tests guided the development of a second prototype. In Phase 3, we conducted additional useability tests and developed a third version. This report describes in detail the features of the second prototype, the results of the useability tests, and the program enhancements implemented in Phase 3. We also tested two methods of delivery: TV and radio traffic reporters and a touch-screen kiosk version.
