What's new in Transportation Data at PSU? Updates on PORTAL and BikePed Portal

Mar 20, 2024

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 ...

How Better Block PSU Helped Launch the Steel Bridge Skatepark

Feb 13, 2024

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.

Transforming the School Commute: PSU Researchers Explore the Impact of Bike Buses

Jan 18, 2024

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...

A Fond Farewell to TREC Associate Director Hau Hagedorn

Nov 28, 2023

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 ...

Using Health Indicators in Transportation Plans

Aug 21, 2023

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.

New Publication Evaluates the Potential of Crowdsourced Data to Estimate Network-Wide Bicycle Volumes

Jul 31, 2023

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—...

How Low-Income Riders Are Affected by Low-Cost Transit Fare Programs

Apr 24, 2023

In recent years, there has been a nationwide push to move from using cars to using other modes of transportation. The benefits of active transportation (that is, walking, biking, and even using public transit) are widely known. Not only can these modes of transportation increase people’s physical and mental well-being, but they also cut down on the negative effects of cars (like their contributing to greenhouse gas emissions and air pollution).

In an effort to encourage more people to use public transportation, and to reduce disparities among riders of varying incomes, Portland, Oregon’s TriMet system developed a low-income fare option for its Honored Citizens Fare (HCF) program. The purpose of the paper—titled “Do Travel Costs Matter? Using Psychological and Social Equity Perspectives to Evaluate the Effects of a Low-Income Transit Fare Program on Low-Income Riders”—was to determine if the low-fare option works to increase access to transit and improve well-being among low-income riders in comparison to other riders. If it does, then it is an effective way to identify and meet the needs of this population and distribute the benefits of transportation investments more fairly.

The HCF program reduces the fare of the public transportation that TriMet provides, which includes buses and...
