Presentation Description

Freight movement is vital to the economy but is a significant contributor to energy consumption, local air pollution, and climate change due to its heavy reliance on the use of fossil fuels. The freight industry is exploring various technologies to decarbonize. To select the best low-carbon technologies and minimize emissions of the national freight system, there is a need for a national-level analytical framework that can guide policymakers, operators, and suppliers. Acknowledging inherent benefits of intermodal freight transport of shipping containers, this study proposes a comprehensive modeling framework to support decision-making in the execution and rollout strategy of decarbonization technologies and guide efficient operations of the national intermodal freight system across road, rail, and marine modes. This framework consists of an Infrastructure Model (IM) and a Logistics Model (LM). The IM is designed to model deployment of low-carbon energy sources and systems, and emerging vehicle operations, and to find the optimal spatial and temporal allocation of energy, vehicle, and terminal resources across the intermodal network. The LM generates a robust and holistic optimization of intermodal logistics operations and shipment routing by simulating stochastic demand and disruptive events within the transportation system. To ensure that the framework provides solutions that are feasible in practice, this study identifies requirements and constraints for alternative fuel technologies and logistics operations, which should be captured in a realistic modeling framework. The proposed framework will provide systematic approaches for evaluating the future intermodal transportation ecosystem by 1) measuring and comparing the potential intermodal system efficiency and resiliency and factors affecting deployment, maximizing utilization of all relevant data; and 2) incorporating the dynamic and stochastic aspects of transportation systems to increase resilience of intermodal freight movement and energy system.

Speaker Biography

Dr. Kyungsoo Jeong joined the National Renewable Energy Laboratory (NREL) in 2018 as a researcher of the Center for Integrated Mobility Sciences. He holds a Ph.D. in Civil Engineering from the University of California, Irvine. His areas of interest include freight demand modeling and analysis, freight data collection approaches, and transportation system optimization. At NREL, he has currently served as a freight transportation modeling lead, aiming to understand freight and urban logistics systems and resolve their problems through advanced data collection/mining and innovative modeling approaches. Prior to joining NREL, he was a postdoc at the Massachusetts Institute of Technology Intelligent Transportation Systems Lab. He studied how new mobility services and emerging technologies affect people and goods movements, and how such technologies can increase the efficiency of the transportation system.
