Elizabeth J. Traut, Ph.D.

Assistant Research Professor
Larson Transportation Institute

Intro

I am an assistant research professor with the Larson Transportation Institute in the Penn State College of Engineering. My research on sustainable transportation uses modeling and optimization to evaluate tradeoffs in design and policy decisions for transportation systems. My research interests include public transit, electric vehicles, charging infrastructure, connected and autonomous vehicles, travel behavior data analysis, economic and statistical modeling of transportation systems, and life cycle assessment. I have experience analyzing travel behavior data and infrastructure data, combining data sets, selecting and fitting models and metamodels, optimizing transportation systems, performing life cycle assessment (LCA), and working with Geographic Information Systems (GIS) for both geospatial analysis and visualization. I have worked with traditional data (surveys) and nontraditional data (GPS traces, crowdsourcing).

Research Experience

Postdoctoral Researcher with RERC-APT

As a postdoctoral researcher with the Rehabilitation Engineering Research Center on Accessible Public Transportation (RERC-APT) in the Robotics Institute at Carnegie Mellon University, I analyzed crowdsourced data from the mobile transit app Tiramisu to identify travel patterns for planning sustainable transit and urban infrastructure.

NSF SEES Fellowship

As a Science, Engineering, and Education for Sustainability Fellow, funded by the US National Science Foundation, I took an interdisciplinary approach to understanding the potential benefits of electric vehicles in urban areas. I performed research towards identifying desirable regional scenarios of electric vehicles and charging infrastructure by determining the impacts of existing land use patterns and public transit availability on life cycle cost and emissions of electric vehicle systems, including charging infrastructure. I held a dual position as a postdoctoral researcher in Urban Studies at the University of Glasgow and in Mechanical Engineering at Carnegie Mellon University. My research mentors were Piyushimita (Vonu) Thakuriah, in Urban Studies at the University of Glasgow, and Chris Hendrickson, in Civil and Environmental Engineering at Carnegie Mellon University. The award abstract is available on the NSF's web site here.

PhD Research

My PhD dissertation work examined tradeoffs between electrified vehicle design and deployment of charging infrastructure, including implications for life cycle cost, greenhouse gas emissions, and fuel consumption of personal vehicles. Methods included life cycle cost and GHG emissions modeling of electrified vehicles and infrastructure for slow-charging, fast-charging, and battery swapping; developing scenarios of electrified vehicle adoption and charging availability; optimizing those scenarios with respect to electrified vehicle design parameters and charging infrastructure deployment; and examining the implications for policy and for engineering design and consumer adoption of plug-in hybrid electric vehicles and pure electric vehicles. My PhD research advisors were Jeremy J. Michalek and Chris Hendrickson.

Prior Research

Prior to my PhD work, my research projects included work on solar thermal absorption refrigeration at the University of Zaragoza in Zaragoza, Spain (2006); work with a PEM fuel cell at the Center for Intelligent Material Systems and Structures at Virginia Tech (2005-2006); and an NSF REU project on technology and policy in sustainable road transportation decisions at Southern University and A&M College, Baton Rouge, Louisiana (2005).
