After 17 years of service to TREC, Portland State University's Transportation Research and Education Center, associate director Hau Hagedorn is moving on to a new position as the Community Investments Manager for Oregon Metro. We will miss her as a colleague, as a model for transportation photos (here she is on the cover of our 2022 Annual Report) and as a seemingly inexhaustible source of energy and inspiration!

During her time at TREC, Hau devoted tireless efforts to improving access to transportation and mobility for people of all ages, communities, and incomes. Her perseverance and commitment have been recognized in the form of numerous accolades and awards. In 2020, she received the CUTC-ARTBA Award for Administrative Leadership from the Council of University Transportation Centers (CUTC) and the American Road & Transportation Builders Association (ARTBA), and the same year she was appointed ...

Managing the entire transportation system requires an integrated understanding of all modes. While the focus of transportation system management and operations (TSMO) has been largely focused on vehicles, understanding how the transportation system can work better for bicyclists, pedestrians, and transit can help provide safe, reliable, and cost-effective transportation options to improve communities and economic vitality for people and businesses.

To encourage practical grounding of transportation from the different vulnerable road user perspectives, PSU's Transportation Research and Education Center (TREC) held a two-day training workshop for a cohort of around 100 Washington Department of Transportation (WSDOT) staff members.

The two-day workshop, which featured classroom presentations as well as mobile tours on bike, foot, and public transportation, was held September 26-28 at Portland State University. Presentations on topics like Transportation System Management, Safety, and Innovative Transportation Operations Solutions were given by both professionals of WSDOT—including Statewide TSMO Development Engineer Pam Vasudeva, and Director of Transportation Operations Dongho Chang—as well as guest speakers including Peter Koonce of the Portland Bureau of Transportation and Jingtao Ma of Traffic Technology Services.

Learning objectives included: 

  • Identify transportation operation practices and approaches that promote...

Since 2011, Portland State University and the Initiative for Bicycle and Pedestrian Innovation have offered a unique opportunity to students: a two-week study abroad course that introduces participants to cities with stellar bike cultures. In past years, classes have explored the Netherlands. This year’s class of fourteen students, led by Professor John MacArthur and supported by funding from the Scan Design Foundation, explored Denmark. See photos from the trip.

Students chose to go on the trip because they knew of the countries’ renown as excellent places to cycle and wanted to learn new strategies that they could bring back to the US. Melissa Kostelecky, a PSU student pursuing a Graduate Certificate in Sustainable Transportation, was inspired to take the trip because she is on a mission to create a better world for her children. In biking, she sees “relief from the isolated, sedentary lifestyle that car dominance has,” “economic freedom,” “a...

In recent years, there has been an increase in the number of people experiencing unsheltered homelessness in the United States. People who are in this situation have nowhere to go at night or during bad weather, except places not designed for humans to sleep: like a car, park, abandoned building, bus or train station, airport, or rest area. Because airports tend to have amenities like public bathrooms and sheltered rest areas, many airports are struggling to respond to the rise in homelessness. A new report from the Airport Cooperative Research Program (ACRP), Strategies to Address Homelessness at Airports, explains what airports, specifically, can do to mitigate the impacts of this crisis. Researchers at TREC worked with PSU's Homelessness Research and Action Collaborative (HRAC) on the project, led by the Cadmus Group.

Research at the Intersection of Transportation and Homelessness

Meeting the needs of unhoused individuals is not core to the mission of airports, and airport operators often do not have specialized expertise to address these needs. Yet, airport staff have in fact needed to address...
