Professor R. Jayakrishnan from the University of California-Irvine presented his research on collaborative consumption in transportation as the first 2017-2018 Distinguished speaker. Professor Jayakrishnan’s presentation “User-Driven Service Order Adjustment for Efficiency in Collaborative Consumption of Transportation Supply,” suggested that a paradigm-shift in transportation, initiated by more peer-to-peer communication, presents a new opportunity for users to consume with more complete information and greater satisfaction. The Distinguished Speaker series is made possible by CMU’s Traffic21, Mobility21, and T-SET UTC.
