Tell us about yourself?
I am a recent graduate from Portland State University, where I received a MS in civil and environmental engineering, and previously completed a BS in civil engineering. During my time as a graduate student at PSU, I was fortunate to work under Dr. Miguel Figliozzi conducting research on factors affecting traffic speeds and speed limit compliance on roads with a high percentage of bicycles (an ODOT research project with co-PI Avinash Unnikrishnan) and studying the spatial distribution of...Read more
A new study launches next month, funded by the National Institute for Transportation and Communities (NITC). Researchers at Portland State University and the University of Texas at Arlington will explore the use of crowdsourced data to estimate pedestrian counts. The project team consists of Sirisha Kothuri and Nathan McNeil of Portland State University, and Kate Hyun and Stephen Mattingly of the University of Texas at Arlington.
WHAT ARE PEDESTRIAN COUNTS USED FOR?
"You know that saying that if you can't measure it, you can't change it? For most streets, we might have some intuitive sense of if there are a lot of people walking there or not, but we rarely have data to back it. This project will assess how crowdsourced data can help to establish the level of pedestrian activity on streets throughout the transportation network," McNeil said.
Knowing how many pedestrians or bicyclists are using a link or a network is the foundation for measuring nonmotorized travel. Count data are useful for monitoring trends, planning new infrastructure, and for conducting safety, health, and economic analyses. The lack of widely available pedestrian count data precludes meaningful safety studies, which have become critically important, especially...Read more

Taking a course is one way to see if one of our PSU graduate degree programs...Read more
The National Institute for Transportation & Communities (NITC) research consortium, led by Portland State University, has awarded $530,419 in total funding for seven new research projects spanning five universities. With the extension of the FAST Act, NITC received one additional year of funding, and given this limited time frame, we emphasized projects that were relatively short in length, relied on existing expertise, and would yield specific outputs and outcomes. Several of the projects have an equity focus, and much of the research aims to make it easier to get around multimodally and/or by walking. The seven new projects are:
- Rumore and Stoker focus on the unique transportation challenges of 'gateway' communities, or small towns adjacent to natural areas that attract large populations. Their previous...
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...

"Transformative Transportation Survey Methods: Enhancing Household Transportation Survey Methods for Hard-To-Reach Populations," is a new article published in the September 2021 issue of Transportation Research Part D. It was co-authored by Amy Lubitow, a sociology faculty member at Portland State University, Erika Carpenter, a sociology graduate student, and Julius McGee, a faculty member in urban studies and planning.
The study explores the challenges that hard-to-reach populations face in completing household activity surveys. Researchers drew on qualitative data from hard-to-reach populations regarding the limits of the Oregon Household Activity Survey and found evidence that the survey methods lack social, cultural, and linguistic applicability for Black, Indigenous and other people of color, as well as low-income populations. The authors argue that Oregon’s household travel survey prioritizes certain ways of understanding and experiencing mobility that are, by default, exclusionary. The article concludes in sharing insights regarding how transportation professionals might ...Read more
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...
