The Better Block PSU program at Portland State University (PSU) has opened our 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 im…

Pedestrians are unlikely to use a marked crosswalk if it is too far out of their way. So how far is too far?

Like so many other things in transportation engineering, the answer is dependent on the context. In this case, variables may include the surrounding roadway characteristics, traffic, and the type of crossing facilities that are available. A pedestrian's decisions can also be affected by how far they are walking, how many streets they have to cross, and other factors.

Researchers at Portland State University (PSU) are embarking on a new study to determine the optimal spacing between marked crosswalks.

Based on their findings, the team will create a tool to inform transportation agencies when to add marked crosswalks (also known as zebra crossings) at unmarked intersections and midblock crossing locations.

Funded by the National Cooperative Highway Research Program (NCHRP), the research team is led by the University of North Carolina at Chapel Hill, and…

Two Portland State University students were awarded Dwight D. Eisenhower transportation fellowships this month at the 104th Annual Meeting of the Transportation Research Board (TRB). Kayla Sorenson and Ana Tijerina Esquino, both graduate students in the Maseeh College of Engineering and Computer Science at PSU, were presented with the awards by the US Department of Transportation (USDOT). This was the second Eisenhower for Sorenson, who also received the fellowship last year. See below for a short interview with each of the PSU Eisenhower Fellows, and if you missed TRB this year, check out some of the PSU research highlights.

The 104th Annual Meeting of the Transportation Research Board (TRB) will take place in Washington, DC. from January 5–9, 2025. Faculty and students from Portland State University (PSU) will be sharing their research and expertise across multiple sessions at the event, which typically attracts over 13,000 attendees each year, making it one of the largest gatherings of transportation professionals and researchers in the world. See below for a few highlights from sessions involving PSU faculty, and check out our student feature story to see what PSU students are doing at TRB. For a full list of sessions with PSU presenters, see the PSU at TRB 2025 Program.

One of the most common locations for fatal motor vehicle–bicyclist crashes is at intersections. A newly published report offers guidance for improving intersection safety, especially in situations where a bike is traveling straight through an intersection and a car is turning across the cyclist's path.

The objective of the study was to develop guidelines and tools for transportation practitioners to reduce and manage conflicts between bicyclists and drivers turning at signalized intersections.

"Reducing Conflicts Between Turning Motor Vehicles and Bicycles: Decision Tool and Design Guidelines" was funded by the National Cooperative Highway Research Program (NCHRP), a program of the National Academies of Sciences, Engineering, and Medicine. The research was led by Toole Design in partnership with Portland State University (PSU), Safe S…
