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…

Several Portland State University (PSU) students worked on research projects that will be shared at the 2025 Annual Meeting of the Transportation Research Board (TRB). We're proud to have high-caliber students at PSU who are contributing to the discussion and technology transfer at the largest transportation conference in the world. See below for a quick look at each student, and check out the PSU program for more details!

Session: Emerging Topics in Bicycling and Micromobility

Evan Howington is a master's student in urban and regional planning. He currently works as a Graduate Research Assistant (GRA) at TREC, supporting faculty advisors John MacArthur and Nathan McNeil. 

Evan will be presenting research in a lectern session on January 6. He'll be sharing insights from the project, "Bike Buse…

Winter term classes begin January 6 at Portland State, and there are some exciting transportation courses available this term. Not a current PSU student? You can still take a course: Anyone interested can register for classes through the non-degree application process, as a post-baccalaureate student, or for free if you're a senior citizen. Taking a course can be a good way to see if one of our graduate degree programs is right for you. 

Check out the listings below to see what's on offer at PSU.

New Program: Urban Studies and Planning Bachelor + Master (B+M) 

The Toulan School at Portland State University has recently added a new…

Over the past several years, in a series of research projects, researchers at Portland State University (PSU) have been developing a new approach to estimate active transportation volumes using machine learning.

This emerging method, which can predict how many people will be biking or walking on any given road, trail or segment of a transportation network at any time, offers promising applications for transportation agencies and state departments of transportation (DOTs). These organizations can use accurate bicycle and pedestrian volume information to track changes over time, prioritize projects, plan and design new infrastructure, conduct safety analyses and estimate public health impacts.

"These methods are still evolving, and it's still in the research phase. But I think the time is not far off when we will start using these methods as more mainstream," said Sirisha Kothuri of the Maseeh College of Engineering and Computer Science, the lead researcher on this series…

The Bike Bus movement is gaining momentum. All over the country, rain or shine, groups of children with adult supervision are hopping on bikes to ride to school together, and the new organization Bike Bus World, led by Coach Sam Balto, has received official nonprofit status.

Last week, the U.S. Department of Transportation announced a $1.1 million federal grant from the Safe Streets and Roads for All (SS4A) program was awarded to Metro. The funds will be used to boost walking school bus and bike bus programs in north Portland. Read more about the new award on BikePortland.

Benefits of the Bike Bus go beyond physical activity: It's an opportunity for kids and parents to socialize, have fun, start the day on a positive note, and save time on driving, parking, and waiting in school dropoff lines.…
