In 2020, the COVID-19 pandemic drastically impacted travel for in-person shopping, commute trips, global supply chains, and food business operations. E-grocery pickup and delivery services saw unprecedented expansions in response. The adoption and use of these e-grocery services have implications for equity and mobility. A PSU masters thesis offers insights: "Adoption and Use of E-Grocery Shopping in the Context of the COVID-19 Pandemic: Implications for Transport Systems and Beyond" by Gabriella Abou-Zeid, a 2021 graduate of Portland State University with a masters in civil engineering.

"While the future adoption and use of e-grocery services is uncertain as the COVID-19 pandemic evolves, our analysis revealed a clear impact of the pandemic on e-grocery shopping behaviors, which has impacts for transportation network demand, safety, and equity," Abou-Zeid said.

Enhancing our understanding of the drivers of (and barriers to) online grocery shopping and its potential "stickiness"—or the extent to which e-grocery use will continue at the same or higher frequencies after the pandemic—is a prerequisite for unpacking current and future consequences of this ecommerce sector on people...

Researchers at Portland State University and Oregon State University have updated the Oregon Department of Transportation (ODOT) Safety Investigation Manual, materials and training resources to assist ODOT traffic investigators with highway safety project investigation, analysis, evaluation, and documentation.

David Hurwitz of OSU worked with Chris Monsere, Sirisha Kothuri and Jason Anderson of PSU to update the manual. The team revised and expanded worksheets used in the safety analysis process and prepared training materials in the form of videos, slide decks, and case study examples to help train ODOT employees and employees from...

Incorporating transportation into the land development process is a big undertaking, with many important angles to be considered. Researchers are translating NITC research on this theme into a popular, easy-to-understand graphic format: comics. Led by an interdisciplinary team at Portland State University and the University of Arizona, they're illustrating transportation considerations in the land development process as a comic to reach a broader audience on this critical topic. 

Related: Read about the NITC Research Roadmap on Transportation and Land Use.

Still in development (the images here are early working drafts, illustrated by PSU student Joaquin Golez and Portland, OR illustrator Ryan Alexander-Tanner), the comics are based on research findings from several projects funded by the National Institute for Transportation and Communities (NITC). The project team is working with readers at neighborhood associations and nonprofits to test this unique approach in sharing research findings. We interviewed three of the project team members Kelly Clifton of PSU, Ryan Alexander-Tanner and Susan Kirtley of PSU to hear how it's going.

Would monetary incentives encourage more people to buy e-bikes? 

Portland State University (PSU) researchers are examining how purchase incentive programs can expand the current e-bike market, and the latest product to come out of this research is a white paper released earlier this month: “Using E-Bike Purchase Incentive Programs to Expand the Market – North American Trends and Recommended Practices (PDF)

The paper offers methods of identifying the most effective program structure for the incentive provider's priorities, and helpful information on how to administer and track the program.

How could a free transportation class for people living in the Salt Lake City region strengthen community conversations and advocacy around local priorities in transportation policy? Researchers at Portland State University (PSU) and University of Utah (UU) explored that question by bringing a well-known learning model from Portland, Oregon to SLC.

For over 25 years, the Portland Bureau of Transportation has partnered with PSU to offer the Portland Traffic and Transportation Course – a free 10-week course designed to provide local community members the skills and knowledge to participate in transportation decisions affecting their neighborhoods. This model has proven to be a success story in public agency-university partnership in community education. Building upon a 2015 project that documented the Portland course and developed a curriculum handbook, the National Institute for Transportation and Communities (NITC) has provided more funding for a pilot community transportation class–the Wasatch Transportation Academy– in Salt Lake, City Utah. Their first class was held on January 24, 2022 (view class recordings here) and ran through...

David Yang, an assistant professor in the Department of Civil and Environmental Engineering at Portland State University, is the principal investigator on two newly-awarded research projects for the Federal Highway Administration (FHWA) in support of its structural engineering programs.

"As the transportation infrastructure continues to age in an ever more uncertain future, it is essential to assess and manage infrastructure risk during the evaluation, maintenance, and rehabilitation processes. These two projects are dedicated to the development of such risk-informed approaches for existing culverts, bridges, and tunnels," Yang said.

In the first project, Framework and Methodology for Risk-Based Bridge and Tunnel Asset Management, an infrastructure team led by Yang with co-PIs Diane Moug, Arash Khosravifar, and Avinash Unnikrishnan will use a three-year grant from the Federal Highway Administration to develop a framework and a methodology for asset management of bridges and tunnels.

Bridges and tunnels need to address the daily transportation needs of the traveling public and provide capacity and emergency service before/during/after extreme events. States may achieve the best possible transportation network performance through a properly planned asset management strategy. This project aims to...

Despite widespread use of walking as a transportation mode, walking has received far less attention than the motor vehicle in terms of national guidance and methods to support planning, designing, and operating safe, functional, and comfortable facilities. To address this gap, the TRB National Cooperative Highway Research Program funded NCHRP Project 17-87: Enhancing Pedestrian Volume Estimation and Developing HCM Pedestrian Methodologies for Safe and Sustainable Communities. Led by Principal Investigator Paul Ryus, Kittelson & Associates partnered with Portland State University and the Highway Safety Research Center at the University of North Carolina to lead research to update pedestrian analysis methodologies in the Highway Capacity Manual (HCM). 

The research team created the following new products, published in 2022 and free to download from the National Academies Press:

  • NCHRP Research Report 992: Guide to Pedestrian Analysis: Documents the state-of-the-practice for pedestrian volume counting, pedestrian safety analysis, and pedestrian operations analysis. A major portion of the research evaluated the effects of safety countermeasures at street crossings on pedestrian quality of service (QOS...

The Better Block PSU program at Portland State University (PSU) has opened the annual call for community organizations to reimagine their streets and underused public spaces in a way to bring people together and reclaim it for their community’s future. 

A partnership between the public spaces advocacy nonprofit Better Block PDX and the Transportation Research and Education Center (TREC) at PSU, students in the Better Block PSU program have developed plans and designs for many community-driven projects that promote equitable placemaking, community building, and active transportation–including the well-known Better Naito project. What began as a PSU student-led initiative for safer and higher capacity bicycle and pedestrian facilities along the Waterfront Park, has gained so much public support that it was permanently implemented by the City of Portland.

Integrated into PSU planning and engineering...
