Jennifer Dill, director of Portland State University's Transportation Research and Education Center (TREC), has been named the inaugural editor-in-chief of the Transportation Research Record (TRR). The TRR—the flagship journal of the National Academies of Sciences, Engineering, and Medicine’s Transportation Research Board (TRB)—is one of the most cited and prolific transportation journals in the world, offering wide coverage of transportation-related topics.
While maintaining her current role as the director of TREC, Dill will begin her duties at TRR on July 15, collaborating with the TRR team and TRB volunteers to enhance the journal’s role in improving the nation's transportation system through high-quality research.
"The Transportation Research Record and TRB have played key roles in my scholarly and professional career. My very first peer-reviewed journal article was published in TRR based on research I did as an undergraduate student with my mentor, Dr. Dan Sperling. That opportunity opened my eyes to the possibility of being a researcher and professor," Dill said.
Prior to entering academia, Dill worked as an environmental and transportation planner at the federal and regional levels. When she first...

You probably don’t live, work, socialize, go to school, and receive health care all in the same place. To get where you need to go in your day-to-day life, you need some form of transportation to get there. But what if that transportation is unavailable? It stands to reason that not being able to get where you need to go would have detrimental effects on your well-being.
To identify transportation disadvantages in their respective cities, professors from the University of Texas at Arlington, the University of Arizona, and the University of Tennessee teamed up to design and test a travel diary app called MyAmble. Travel diaries are built for recording trips taken, but they often lack the ability to capture travel disadvantage or latent travel demand. In this context, travel disadvantage refers to essential trips that people plan to take but are unable to complete for some reason, e.g., their car breaks down or they don’t have gas money. Latent travel demand refers to trips that people would take but don’t bother to plan due to transportation barriers or safety concerns. The aim of MyAmble...

Homes, Not Offices: Researchers Recommend Changes to Transit Station Area Development After COVID-19
A new report offers lessons for post-pandemic transit policy and planning. Notably, it calls for planners to downplay the role of offices in transit station areas and increase the opportunity for people to live in them. Researchers Arthur C. Nelson and Robert Hibberd published "Transit Station Area Development and Demographic Outcomes (PDF)," updating their longitudinal analysis of the impacts of development near transit stations.
The new report includes a foreword by U.S. Congressman Earl Blumenauer. An excerpt reads:
Read more"In this report, Arthur C. Nelson, Emeritus Professor of Urban Planning and Real Estate Development at the University of Arizona, and Robert Hibberd, a doctoral student, chronical numerous economic and demographic changes that occurred in transit station areas between the Great Recession that ended in 2009 and the pandemic that started in 2020. Through detailed analysis of 57 transit systems operating...
According to new research, transit-oriented development (TOD) can address the equity challenge of "spatial mismatch," where urban residents are isolated from relevant employment centers, and significantly improve employment access.
"Job-Worker Balance & Polycentric Transit-Oriented Development: Toward Indices and Spatio-temporal Trends," funded by the National Institute for Transportation and Communities (NITC), examines how transit-oriented development (TOD) affects employment access and addresses urban equity challenges, particularly in the context of essential workers and the COVID-19 pandemic.
In addition to demonstrating that TOD can help mitigate spacial mismatch, the study also highlights that TOD can lower transportation costs and enhance job-worker balance by providing more accessible central locations. Additionally, higher levels of spatial density and land use mix can aid in managing pandemics by improving access to essential jobs, which often involve low-income occupations that require face-to-face interactions.
The dissertation's author, Robert Hibberd, is a doctoral candidate at the University of Arizona (UA). An Eisenhower Fellow and NITC Dissertation Fellow, Hibberd devoted his doctoral research to exploring how the spatial distribution of resources and infrastructure in cities affects access to employment and essential services, ...

Portland State University's Transportation Research and Education Center (TREC) maintains two large, public transportation data lakes: PORTAL and BikePed Portal. The latest round of funding for PORTAL, in the amount of $1.6 million, was awarded in February 2024 and will cover PORTAL's activities through the next five years. BikePed Portal, too, recently received $100K for another year of funding, and both are the focus of some exciting innovations in transportation data.
The two centralized data repositories, unique both in their size and in the fact that they are accessible (PORTAL is freely available to the public, and BikePed Portal has limited public access as well), are supported by multiple federal, state, and regional agencies. Federal funding for PORTAL comes from the Federal Highway Administration (FHWA)'s Surface Transportation Block Grant (STBG) funding, suballocated by Metro’s ...

Portland's Old Town neighborhood is getting a new skatepark, and a team of PSU transportation students were instrumental in bringing the project from idea to reality.
Given the project of activating a vacant lot on the west side of the Steel Bridge by transforming it into a community skatepark, students in the Spring 2023 bike-pedestrian planning class created a set of design options, a weighted decision matrix, and a memorandum of existing conditions for the site. They also developed performance measures to determine how best to meet the project's objectives of activating the space, creating a welcoming environment, and stimulating local business activity.
Their work provided a basis for ongoing conversations with stakeholders around the project, which ultimately resulted in a green light: Funding for the new skatepark was announced in January by Commissioner Dan Ryan, who oversees Portland Parks & Recreation. Work is slated to begin this spring on property acquisition, community engagement and design of the 35,000 square foot facility.

When you think of your dream home, what do you think of? Perhaps you envision a house with enough space for your whole family to be comfortable. Maybe you’ll be close to your extended family…or maybe you won’t, depending on your personal family dynamic. It will be in a safe neighborhood, perhaps with access to amenities that promote a healthier lifestyle, like green spaces and walking trails. School, work, grocery stores, and the doctor’s office will be easy to access. The home won’t cause you financial stress. It will feel like yours.
You may not be surprised to hear that many people look for these qualities when considering a place to live. With the study “Housing Choice, Transportation Equity, and Access to Opportunities in Refugee and Immigrant Communities,” professors at the University of Texas at Arlington sought to collect qualitative data about factors and values that caused refugee and immigrant populations in Dallas County, Texas to want to move. This demographic makes up a significant part of Dallas County’s population; almost one fourth of people who live there were born outside the United States. By better understanding the needs of this population, policies could be set in place that address inequity and make the community a more welcoming, accessible place for all. The paper focuses on the roles that primary and secondary mobility play in the housing choices of immigrants and...

The trip to and from school is made by nearly every child in Oregon every school day. Bike and walk buses, organized groups of school children, parents, and ride/walk leaders, seek to encourage biking and walking to school. A new research project at Portland State University's Transportation Research and Education Center (TREC) will gather information on bike buses nationwide, inspired by the success of Sam Balto's bike bus initiative at Alameda Elementary School in Portland, Oregon.
Balto, a physical education teacher, catapulted into the limelight in 2022 after establishing a weekly bike bus involving over 100 students commuting to school on two wheels. Its success and popularity prompted a broader initiative to understand and promote the benefits of bike and walk buses across the United States.
Researchers John MacArthur and Nathan McNeil, along with Evan Howington, a student in the Master of Urban and...
