A prototype radio frequency identification (RF/ID) tag system was designed and tested. Hardware and software were designed for an RF/ID tag system for automatic data collection on transit user movements. Work on Stage 1 involved assessing the RF/ID design for applicability to transit systems. Transit operator configuration requirements were evaluated, software and database requirements were reviewed, a preliminary system design configuration was established, and a representative bus route was selected. In Stage 2, system hardware and software specifications were developed, and a prototype RF/ID system for collecting, storing, and translating transit data was designed and built. The University of Virginia Transportation Services (UTS), which serves the student and staff population at UVA, participated in the project. In Stage 3, trial testing of RF/ID system using the Hereford College Dormitory-Hospital Complex route in the UTS system was performed and system performance and operational viability were ascertained. Potential coupling of RF/ID data collection with AVL systems was examined.
