Future of Transportation Automation and Energy
Transportation affects major environmental, economic, and equity outcomes, and our research informs decisions about emerging transportation energy and automation technologies. Our students are conducting systems analysis and simulation on how the transition to alternative fuels and automation affects greenhouse gas emissions, energy consumption, and air pollution. We are also assessing how automated vehicles affect crashes, miles traveled, traffic congestion, infrastructure costs, and other outcomes. Our 2008 paper helped define modern plug-in vehicle life cycle assessment broadly across the field, and our 2014 report on autonomous vehicles and public policy helped shape future research directions in this field. Our 2018 paper assessed the life cycle impacts of drone package delivery, and our group continues to examine the impact of automation and advanced technology on the transportation sector.
One journal paper on autonomous vehicles received the Elsevier Atlas Best Paper Award, for the best paper across all of their 2,600 journals. Prof. Samaras was also guest on 99% Invisible, NPR's Radio Times, and The Energy Transition Show discussing the implications of vehicle automation.
