"Efficiency from User-driven Service Order Adjustments in Collaborative Consumption of Supply in Transportation"

R. "Jay" Jayakrishnan
Professor, Department of Civil and Environmental Engineering & Institute of Transportation Studies, University of California at Irvine



Newer technologies and high market penetration of personal communication systems along with the advent of autonomous and connected vehicle systems bring up many new possibilities for different paradigms of operation in transportation systems. Facilitated by significantly more peer-to-peer (P2P) communication, users in the future can consume transportation supply with more complete information on individual heterogeneity in utility satisfaction. Several possibilities exist in such a world of shared economy, with regard to using road and vehicle space in a temporally efficient manner. Breaking the traditional First-Come-First-Served paradigms with P2P monetary exchanges to compensate for utility disparities can improve system and user level efficiency. Car-sharing and ride-sharing are two of the more well-known systems of relevance. Autonomous vehicles bring up another dimension in terms of shared ownership as well. There is also recent research in collaborative negotiated consumption of other elements of transportation supply such as signal timings, and lane space availability. This presentation focuses on the possibilities, and discusses recent research into such mechanisms for signal and lane usage, and ride-matching in shared-ride systems. It also describes the associated pricing and behavioral issues where economic concepts such as envy-freeness are introduced as a basis for such schemes to be user-driven and equitable, without system level mandates.



Prof. R. Jayakrishnan has been in the faculty of Civil and Environmental Engineering at the University of California at Irvine since 1991, after receiving his doctorate from the University of Texas at Austin. His research interests are in a variety of topics such as Traffic Flow Theory and Simulation, Transportation Systems Analysis, Network Modelling, Decision Theory, Intelligent Transportation Systems and Public Transit Design. Prof. Jayakrishnan has been a member of several professional committees, has served in the editorial committees of journals such as the ASCE Journal of Transportation Engineering and Transportation Research Part-C, and has served in several committees of the Transportation Research Board. He was a chair of the TRB subcommittee on Route Choice and Spatio-Temporal Processes. A paper co-authored by him received the Pyke Johnson Award for the best paper in planning submitted to the Transportation Research Board in 2009. Twenty doctoral students have graduated under his advice and he has over 100 refereed publications to his credit. He has been a visiting professor at other institutions such as the Ajou University in South Korea and the Amrita University in India.
