In 2022, a PSU Master of Urban and Regional Planning (MURP) team made headlines with their strategies to improve safety for houseless pedestrians. Cities across the U.S. are facing alarming increases in traffic fatalities, especially among the number of pedestrians who are struck and killed by drivers. In 2021, 70 percent of all pedestrian fatalities in Portland were of people experiencing houselessness. The MURP team Street Perspective, made up of Peter Domine, Nick Meusch, Asif Haque, Angie Martínez, Sean Doyle, and Meisha Whyte, investigated how to reduce the risk of being hit and killed specifically for unhoused people. 

As the Portland Bureau of Transportation (PBOT) is updating the city's Vision Zero Plan, the team provided PBOT with recommendations to reduce the risk of pedestrian fatalities among the city's vulnerable houseless communities.

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...

Last year, a car driver hit a César Chávez K-8 School student at the intersection of N. Portsmouth Ave and N. Willis Blvd in Portland, OR. It underscored what parents, teachers and Portland community members have been demanding for many years: increased investment in traffic safety at schools during pick up and drop off hours.

What’s more: Portsmouth’s residents already had a lot of ideas of how to improve pedestrian safety at this intersection.

Seeking to help the community take action on these ideas, Safe Routes to School advocacy professionals William Francis and Hanna Howsmon at Community Cycling Center and César Chávez teacher Sam Balto recommended this intersection as a potential quick build project for the Better Block PSU pathway program-–a partnership between the volunteer-led group Better Block PDX and the Transportation Research and Education Center (TREC) at Portland State University that pairs transportation students with community-led projects. 

“PSU students support community members with the technical aspects of infrastructure improvements–elevating and materializing their ideas by developing plans, designs, and engineering concepts. It’s a shift from the status quo with a ground-up approach, and their transportation expertise can help community members in navigating the permit process or proposing informed solutions to the city,” shared Hau Hagedorn, TREC Associate...

One of the most common locations for motor vehicle-bicyclist crashes is at controlled intersections. Particularly dangerous is the conflict between through bicyclists and turning drivers (either left or right). Despite widespread acknowledgement of this problem, transportation engineers and planners still lack definitive guidance on how to safely and effectively design for bicyclists at intersections in the United States.

In a newly contracted project, awarded to Toole Design Group by the National Cooperative Highway Research Program (NCHRP), a team of researchers will identify design best practices to reduce conflicts at intersections. In addition to Toole, the team includes researchers from Portland State University, Oregon State University (David Hurwitz), and Safe Streets Research & Consulting (Rebecca Sanders). Christopher...

In recent years, there have been over 600 bicyclist fatalities annually in the United States. This sobering statistic has motivated a number of recent studies, including the recently released National Transportation Safety Board study, “Bicyclist Safety on US Roadways: Crash Risks and Countermeasures (PDF). ” That report notes that midblock crashes account for a disproportionate number of bicyclist fatalities and severe crashes, and that separated on-street bicycle facilities may reduce the likelihood of these crashes. However, there are only limited data on the safety outcomes of separated on-street bikeways in the U.S., despite their increasing popularity...

When buses and bikes share space, it's complicated. Not only are there safety risks for cyclists, but also potential delays in bus service and stressful navigation for bus operators. The quest to increase bus speeds—and plausibly...

Psychology teaches us that implicit biases—attitudes we hold on a level below consciousness, and may not even be aware of—can have a heavy influence on split-second decisions.

In a fast-paced activity like driving, with a lot of moving parts in a complex environment, we make those snap decisions all the time. There are obvious safety implications to this, particularly for the most vulnerable road users. That’s why TREC researchers are becoming more and more interested in studying implicit bias and social psychology as it relates to transportation behavior.

The latest report from the NITC program, Exploring Drivers’ Attitudes and Behaviors toward Bicyclists: The Effect of Explicit and Implicit Attitudes on Self-Reported Safety Behaviors, is a dissertation by NITC fellow Tara Goddard.

With a focus on driver-cyclist interactions, Goddard dives into the social psychology of roadway interactions and comes up with some interesting takeaways for practitioners and researchers. Before moving to Portland in 2011 to begin her Ph.D., Goddard was the bicycle/pedestrian coordinator for the City of Davis, California, and says that it’s important to understand the mechanisms at...

The first Transportation and Communities Summit picked up where its predecessor summit left off, offering a day of professional development opportunities and a few new touches. Around 275 people attended this year’s summit, held Sept. 15 at Portland State University.

The highlight for many, according to post-event surveys, was the keynote address by author and sociology professor Eric Klinenberg. Keeping alive a tradition from earlier Oregon Transportation Summits, Klinenberg’s address gave insight into an issue that intersects with transportation—in this case, the rise of single-occupant households—without directly detailing the transportation implications.

The breakout sessions allowed attendees to delve deeper into topics directly related to their professions. A full 54 percent of survey respondents called the breakout sessions the most valuable piece of the summit program. The most highly rated sessions were “Waiting to Connect,” on connected vehicles; “Something from Nothing,” on funding; “Zeroing in on Safety,” on Vision Zero; and “Baby, You can Drive my Car;” on the sharing economy. 

Slides from all these presentations are available at the summit page.

For the first time, summit sessions were Webcast for those who couldn’t attend in person...

Christopher Monsere, a civil and environmental engineering professor at Portland State University whose research focuses on multimodal safety, has been selected to be a member of Portland, Oregon's new Vision Zero Task Force.

Vision Zero is a multi-national safety project which aims to eliminate fatalities and serious injuries on the roads.

The Portland Bureau of Transportation, in an effort to make Portland's transportation system the safest possible, is taking steps to move toward zero traffic-related fatalities in the next 10 years.

To connect this work with a wider community effort, Mayor Charlie Hales kicked off the Vision Zero Task Force with a gathering last Monday, August 17, at the intersection of 82nd Avenue and Division—two of Portland’s most lethal corridors.

The Task Force is a multi-disciplinary and multi-jurisdictional group of members with a clear mandate: to work together and create a community-wide action plan with real solutions. Its members were chosen by Hales and Transportation Commissioner Steve Novick based on their qualifications and commitment.

Monsere will serve in an advisory capacity and investigate solutions as a TREC researcher. His expertise in the area of multimodal safety makes him uniquely qualified to offer...
