2014-2015 UTC Graduate Research Assistant Scholars
Jim Dunshee (Civil and Environmental Engineering)
The EPA’s Motor Vehicle Emissions Simulator (MOVES) will need to incorporate advancing vehicle technologies and new pollutant emissions standards in order to remain an effective tool for transportation planning. The broad scope of Jim’s research explores implementing the most recent version of MOVES (2010b) with the ability to model hybrid-electric vehicle emissions, with a focus on particle number (PN) emissions. In order to evaluate MOVES modeling results against real-world data, this work utilizes on-board emissions data collected from comparable model conventional and hybrid-electric vehicles.
Saghar Sadeghpour (Civil and Environmental Engineering)
Many research groups have studied measuring vulnerability or robustness of a transportation network. The Network Robustness Index (NRI) and Network Trip Robustness (NTR) developed by UVM researchers has the advantage of using the road network and travel demand matrices that are typically available in a state or regional travel demand model. The objective of Saghar’s research is to development a “proxy” origin and destination (OD) matrix using E911 building data for the state of Vermont in order to calculate the NRI and NTR for all roads state-wide not just the more major roads currently in the travel demand models. This adaptation will allow researchers to identify critical road segments and measure the system-wide robustness in the transportation network based on capacity-reduction approach. In addition to estimating the NRI and NTR for the whole state of Vermont, she will compare the robustness measures for the full network with the robustness measures of the state-wide model to assess whether or not full road networks and OD matrices are needed for overall system robustness measures.
Paola Rekalde Aizpuru (Civil and Environmental Engineering)
Paola is currently working on spatial analysis of Vermont crash data and Vermont road system characteristics, analyzing guardrail locations and both horizontal and vertical road curvatures where those crashes occurred in order to identify any relationships and provide with construction advice. In addition, she is working on understanding transportation opportunities and behavior among specific groups in Vermont, such as teenagers, disabled citizens and veterans. She is looking at their mobility options and habits in relation to the current state of public transit and transportation systems in Vermont.
Anna Schulz (Public Administration, Community Development and Applied Economics)
Anna’s research focuses on how transportation governance networks assess resilience, primarily as it relates to flooding. She is currently collecting and analyzing data on how New England states prioritize and fund bridge projects.
Phoebe Girouard Spencer (Rubenstein School for Environment and Natural Resources)
Phoebe’s research effort employs American Time Use Survey data to measure pedestrian behavior between and among seasons and climatic regions while controlling for socio-demographic characteristics of the respondents and their household. Her research focus is continuing to narrow toward equity and social justice in active transportation systems, which will play a role in her next project, using GIS and geostatistical techniques to understand preferences in transportation and built environment by home location in Chittenden County.
Xiao’s current research is focused on building the indicators and standards for Transportation Recreation Opportunity Spectrum (T-ROS), and the visitors’ perception of the diversity of transportation in recreational areas. I also engaged in the research project “Transportation as a barrier,” which focused on whether the transportation is a barrier for the minorities to visit national parks, and how to increase the visitation of minority groups.
Sean Neely (Civil and Environmental Engineering)
Sean came here with a consulting background in planning & GIS. Before his current role as a graduate research assistant, Sean provided the Transportation Research Center with geospatial analysis and project support on various projects. These include: travel behavior in Northern New England and Upstate New York; overnight travel behavior across the United States and into Canada; work zones and travel speeds in Vermont; roadway curves, guardrails and crashes in Vermont; transportation for people with physical disabilities in Chittenden County, Vermont; and transportation for veterans throughout Vermont. As a graduate research assistant, Sean is studying intercity travel behavior. This work investigates how people make intercity trips, with the influence of technology, communication, and information access.
