摘 要：Increased use of public transportation is an effective means of decreasing roadway congestion and its associated externalities. To increase the use of public transportation under economic and resource constraints, it is important to improve the understanding of public transportation supply characteristics and demand behavior and make use of this understanding to improve planning and operations functions. Analyzing and interpreting in situ public transportation conditions that are readily accessible and observable can greatly improve this understanding. Project investigators previously worked with The Ohio State University (OSU) Campus Area Bus Service (CABS) and a private technology provider to equip the CABS network with state-of-the-art sensing, communications, and passenger information systems that are presently used to provide realtime bus arrival information to CABS users and ridership and location information to CABS operators and planners.
