Public transportation agencies are well acquainted with the consequences of unsheltered homelessness. A new report published this month provides timely and valuable information about how transit agencies can support people experiencing homelessness in our communities and minimize the impacts on public transportation services and facilities.

The report, funded by the Transit Cooperative Research Program (TRCP), was co-authored by TREC's sustainable transportation program manager John MacArthur along with Marisa Zapata, Anna Rockhill and Rebeca Petean of Portland State University's Homelessness Research and Action Collaborative (HRAC). The researchers will present on the project in an upcoming webinar (date TBA) in March 2024, hosted by the Transportation Research Board (TRB). 

While transit agencies cannot address the underlying causes of homelessness, there are opportunities to work with local partners to be a part of helping individuals in need, while providing a safe, reliable, and customer-friendly experience for all riders.

"I think transit agencies can no longer look at themselves as just providing transit. Their role in the way a community functions is so much bigger than that. Transit is the connection that gets a lot of people to essential services that will improve their lives. Transit agencies need to rethink how they are serving all riders, including people experiencing homelessness, and how they can - more humanely and with...

Researchers Ivis Garcia, Sadika Maheruma Khan, and Kevin Fagundo-Ojeda of the University of Utah with Miriam Abelson and Nicholas Puczkowskyj of Portland State University have published a new article in the November 2022 issue of Transportation Research Part D: Transport and Environment.

Scholarship on gendered mobilities has shown that women experience transit differently than men do, particularly regarding personal safety. The article, "Harassment of low-income women on transit: A photovoice project in Oregon and Utah," makes a unique contribution to this body of literature because it shows that women feel targeted also based on their racial or ethnic identity and not only their gender. The article discusses women’s actions every day to increase their sense of safety.

Research has shown that low-income women who are...

A group of nine transportation students traveled to Denmark and Sweden this past summer, to meet with planners and engineers and get a feel for on-the-ground transportation in Copenhagen and Stockholm. They explored the area by rail, foot, bike and boat, in between presentations and tours led by professionals. 

Portland State University's Transportation Research and Education Center (TREC)'s associate director, Hau Hagedorn, and sustainable transportation program manager, John MacArthur, led the Initiative for Bicycle and Pedestrian Innovation (IBPI) Study Abroad program. See photos from the trip.

In past years they've traveled to the Netherlands to experience the Dutch approach to cycling infrastructure and multimodal travel. This year, they decided to expand the mission. Copenhagen, like Amserdam, is sometimes referred to as the cycling capital of the world. Stockholm, along with some...

Researchers Aaron Golub, John MacArthur and Sangwan Lee of Portland State University, Anne Brown of the University of Oregon, and Candace Brakewood and Abubakr Ziedan of the University of Tennessee, Knoxville have published a new journal article in the September 2022 volume of Transportation Research: Interdisciplinary Perspectives

Rapidly-evolving payment technologies have motivated public transit agencies in the United States to adopt new fare payment systems, including mobile ticketing applications. The article, "Equity and exclusion issues in cashless fare payment systems for public transportation," explores the challenges facing transit riders in the U.S. who lack access to bank accounts or smartphones, and potential solutions to ensure that a transition to cashless transit fares does not exclude riders. Learn more about the project and read an open-access version of the final report.

The study asks: who is most at risk of being excluded by the transition to new fare payment systems and how would riders pay transit fares if cash payment options were reduced or eliminated? Researchers answer these questions using intercept surveys of 2,303 transit riders in Portland-Gresham, OR, Eugene, OR, and Denver, CO.

If you could securely pick up your packages on your commute by public transit, from any carrier—be it USPS, FedEx, UPS or other companies, would you? Transit agencies could be missing a potential strategy to increase ridership by offering common carrier parcel lockers at transit facilities. 

Mitigating the demands on our urban transportation networks by consolidating parcel deliveries at high trafficked transit facilities could also benefit retailers, logistics and carrier companies, and consumers. But how do we ensure the equitable distribution of these sites for disadvantaged populations, while keeping accessibility in mind?

Using real world data from the Portland, OR region, a new study from researchers at Portland State University (PSU) offers a multiple-criteria approach using accessibility and equity metrics, including ridership, mode of transportation, spatial distribution, and sociodemographic profiles of coverage areas. 

Limited Free Access: The article in Transportation Research Record, "Accessibility and Equity Analysis of Transit Facility Sites for Common Carrier Parcel Lockers," by Katherine Keeling, Jaclyn Schaefer and Miguel Figliozzi, will be...

How can we use a variety of data-driven speed management strategies to make transportation safer and more efficient for all modes–whether you’re driving, walking or taking transit?

The project was led by Yao Jan Wu, director of the Smart Transportation Lab at the University of Arizona. Co-investigators were Xianfeng Terry Yang of the University of Utah, who researches traffic operations and modeling along with connected automated vehicles, and Sirisha Kothuri of Portland State University, whose research has focused on improving signal timing to better serve pedestrians. Join them on Sept 15, 2021 for a free webinar to learn more.

"We want to improve mobility for all users, be it pedestrians, vehicle drivers or transit riders, and there are different strategies to do this. How do we harness data to drive us to these strategies?" Kothuri said.

Funded by the National Institute for Transportation and Communities (NITC), this multi-university collaboration addressed the question from three angles:

  • Wu and his students in Arizona looked at the impact of speed management strategies on conventional roadways...

Research demonstrates that marginalized populations experience significant barriers in accessing transit. The Transportation Research and Education Center (TREC) and the Homelessness Research & Action Collaborative (HRAC) at Portland State University are working with the University of Utah in a project funded by the National Institute for Transportation and Communities (NITC) to understand how people from selected historically marginalized communities experience discrimination and harassment on transit and in public areas such as sidewalks, bus stops, and transit platforms when accessing transit.

The study will be conducted in two sites: Portland, Oregon and Salt Lake City, Utah. In Portland, the study population will include racially and ethnically diverse people experiencing homelessness and people who identify as transgender and gender nonconforming; and ride TriMet. In Salt Lake City, the study population will include people experiencing homelessness as well as diverse groups based on their gender, racial, and ethnic identity; who ride Utah Transit Authority. We are seeking transit riders to help inform the study through photos and interviews. Participants will be compensated up to $50 for their labor. The researchers will be recruiting participants for this study through the end of August.

We're proud to announce the publication of a new NITC dissertation: "Methodologies to Quantify Transit Performance Metrics at the System-Level," by Travis Glick of Portland State University.

Performance metrics have typically focused at two main scales: a microscopic scale that focuses on specific locations, time-periods, and trips; and, a macroscopic scale that averages metrics over longer times, entire routes, and networks. When applied to entire transit systems, microscopic methodologies often have computational limitations while macroscopic methodologies ascribe artificial uniformity to non-uniform analysis areas. These limitations highlight the need for a middle approach. This dissertation presents a mesoscopic analysis based around timepoint-segments, which are a novel application of an existing system for many transit agencies.

In the United States, fix-route transit is typically defined by a small subset of bus stops along each route, called timepoints. For this research, routes are divided into a consecutive group of bus stops with one timepoint at the center. Each timepoint-segment includes all data collected in that segment during one hour of operation. Visuals for congestion and headway performance, based on the aggregated datasets, are designed to...

Our multi-year study on automated transit fare collection offers a key finding that won't surprise you: Despite the convenience, the rush toward cashless fare systems has created barriers for lower-income riders seeking to use transit. Results from focus groups, surveys, and a review of current transit agency practices suggest that continuing to accept cash is a crucial way to keep transit accessible. However, dealing with cash has drawbacks: it’s time intensive and expensive. Using a detailed cost-benefit model, the researchers explored the costs for agencies to maintain some cash options and found that some simple approaches can be quite effective. The best bang for the buck? Cash collection on board buses.

Launched in 2019, the research project "Applying an Equity Lens to Automated Payment Solutions for Public Transportation" was supported by a Pooled Fund grant program from the National Institute for Transportation and Communities (NITC) and conducted at three universities: Portland State University (PSU), the University of Oregon (UO), and the University of Tennessee, Knoxville (UTK). The other funding partners were City of Eugene, OR, City of Gresham, OR, Lane Transit District, Clevor Consulting Group, and RTD (Regional Transportation District) Denver....

Led by Xiaoyue Cathy Liu of the University of Utah (UU) and funded by the National Institute for Transportation and Communities, researchers have created a web-based modeling tool (see GitHub repository built for the Utah Transit Authority) that enables U.S. transit providers to explore the impacts of changing over their systems to electric buses*. The researchers ran the model for TriMet in Portland, OR as well, with TriMet results and analysis presented in the final report (PDF).

"The interactive visualization platform lets users explore various electric bus deployment budget scenarios, so that transit agencies can plan the most cost-effective way to transition their fleet from diesel to electric buses – while prioritizing disadvantaged populations," Liu said.

The research team, at University of Utah, Portland State University (PSU), and University of California, Riverside, set out to answer three questions: 

  1. What costs and benefits are associated...
