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 ...

Portland State University (PSU) researchers will create a "Research Roadmap for Institutionalizing Transportation Equity," in an attempt to identify and standardize best practices relating to social equity in transportation organizations. Led by principal investigator Aaron Golub, a professor in the Toulan School of Urban Studies and Planning at PSU, the project is supported by a $250,000 funding contract from the National Cooperative Highway Research Program (NCHRP). Along with PSU researchers, the project team also includes AOA (Ontiveros & Associates, LLC) and Bills Formula Consulting LL.

Read more about the project: NCHRP Project 20-123(19) Equity Research Roadmap.

WHAT WILL THE EQUITY ROADMAP DO?

All people, regardless of their background, income, or physical abilities, need access to safe, affordable, and convenient transportation options and services. State departments of transportation and their partner regional planning organizations seek to improve the equity outcomes of their decision-making practices and investments. The research roadmap will help define broad research areas and gaps for...

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...

Since 2016, the Transportation Research and Education Center (TREC) at Portland State University has hosted a free transportation summer camp for high school students. Isa Swain, an incoming sophomore in civil engineering at Portland State University, exemplifies why TREC engages in K-12 education: students' interest in transportation doesn't have to wait until the university. After attending the summer camp in 2020, Swain came to PSU to study civil engineering last year and is now on track to become a transportation professional. She also served as a camp counselor for this year's cohort of students. We interviewed Isa to get her perspective on the PSU summer camp and what it offers to students.

ABOUT THE CAMP

The 2023 transportation summer camp was held last month, with activities including bike tours, a jet boat tour, an exploration of the inside of a couple of Portland's bridges, a bridge-building contest, and of course the presentation of students' final projects to friends and family. Guest instructors shared their expertise and career insights with students, coming from local organizations including PSU, the City of Portland, The Street Trust, the Oregon Department of Transportation, Cycle Oregon, and Alta Planning + Design.

As a social determinant of health, transportation significantly contributes to people's well-being. Walkable, bikable, transit-oriented communities are associated with healthier populations. People in such communities are more physically active, less likely to be injured due to a crash, and less exposed to air pollution.

Because of these and other factors, researchers and practitioners have called for health indicators as one way to integrate public health concerns into transportation decision-making. However, it is unclear how indicators are actually being used and what their impact is on policy.

Research conducted by Kelly Rodgers, a National Institute for Transportation and Communities (NITC) Dissertation Fellow, explored how health-related indicators are being used in municipal transportation plans, whether they are institutionalized into transportation agency decision-making processes, and what influence they have on administrative decision-making.

"I have for some time been working at the intersection of health and transportation, and was interested in how health could be better integrated into transportation decision making. And I have also previously done work on performance measures. And so I kind of combined those two things, to see if health-related indicators were a way of getting transportation agencies to consider health in transportation planning," Rodgers said.

How can emerging data sources most effectively be integrated with traditional sources? A new article in the July 2023 issue of Transportation Research Record: Journal of the Transportation Research Board reports that rather than replacing conventional bike data sources and count programs, old “small” data sources will likely be very important for big data sources like Strava and StreetLight to achieve their potential for predicting annual average daily bicycle traffic (AADBT).

The article, "Evaluating the Potential of Crowdsourced Data to Estimate Network-Wide Bicycle Volumes," was authored by TREC researchers Joe Broach, Sirisha Kothuri and Nathan McNeil of Portland State University along with Md Mintu Miah, Kate Hyun and Stephen Mattingly of the University of Texas at Arlington, Krista Nordback of the University of North Carolina, Chapel Hill; and Frank Proulx of Frank Proulx Consulting, LLC.

Transportation agencies have invested heavily in count infrastructure and models to estimate motor vehicle volumes through networks. Efforts to develop network wide bicycle volume estimates have been hampered by lack of bicycle counters and limited other data sources from which to draw volume estimates. Until recently, most data on bicycle activity came from national or regional household travel surveys, along with observed counts of cyclists—...

Portland State University (PSU) has been awarded a new contract by the National Cooperative Highway Research Program (NCHRP). To create a "Guide for Addressing Encampments on State Transportation Rights-of-Way," $350,000 in research funding will go toward developing a set of best practices to help state transportation agencies respond to temporary encampments on state transportation rights-of-way. These areas, including paved roads, bridges, and other transportation facilities managed by the state, are often some of the most accessible public land for people to occupy who have nowhere else to go.

A growing trend of encampments on state rights-of-way has presented unprecedented challenges for state departments of transportation (DOTs) in the design, construction, and maintenance of transportation facilities. As owners of some of the largest stretches of public land, DOTs must maintain the land for public use, and may lack resources to address the social welfare aspects of this stewardship. There are no widely accepted guidelines relating to this trend. By supporting this research, the NCHRP aims to help state DOTs respond to encampments in a way that assures rights-of-way remain open while...
