This course presents an overview of ITS applications in public transit management and operations with emphasis on three specific areas. Applications and technologies employed in the Public Transit Operations domain include advanced communications systems, AVL, automated passenger counter systems, and electronic payment systems, to name a few. These, and several other technologies are described in the first section. The second area explored is that of Traveler Information Systems for Transit and their benefits, components, and requirements. The last section introduces Traffic Signal Priorities for Transit (TSPS) benefits, requirements, and technologies used. Case-studies and examples of implementations in each area illustrate the three sections of the course.
