Minnesota Guidestar comprises more than 60 intelligent transportation systems (ITS) operations tests, projects, and research studies. One of those projects--Travlink--works as an on-line traveler-information project with a bus-tracking component. A computer-aided dispatch/automatic vehicle location system works in conjunction with the global positioning system and a geographic information system to gather and update bus transit information that is displayed on electronic signs, interactive touch-screen public kiosks, and personal computer display monitors. The Travelink study was initiated to improve the commute from the western suburbs of Minneapolis to its downtown or the University of Minnesota along the 18-km (11-mi) "transit friendly" Interstate 394. This article describes the Travlink project in detail and highlights the scope of the Travlink evaluation currently under way.
