Portland State University (PSU) researchers have partnered with TriMet to evaluate the design of a new shared-use bus platform that incorporates a sidewalk-level bike lane. The project, FX2 Shared Bicycle & Pedestrian Platform Evaluation, assessed how well the new design is working for transit riders and other road users along Portland's Southeast Division Street.

The most common bus and bike lane design typically has a bike lane directly adjacent to the right side of the bus lane with no physical barrier. This presents several safety concerns. In this scenario, a bike behind a bus would have to wait behind or pass the bus by riding into traffic. As vulnerable road users, these conflicts pose a potentially serious risk to bicyclists.

The FX2-Division is a Frequent Express (FX) bus line that runs from downtown Portland to Gresham. The transit service began operations in September 2022. To accommodate passing bicyclists and transit riders accessing the new FX2 line, TriMet worked with the City of Portland and a broad group of stakeholders and partners to create a design that would allow bikes to stay separated from automobile traffic, with the bikeway passing through the platform area next to where people wait for the...

Portland State University transportation researchers will partner with the Portland Bureau of Transportation (PBOT) to evaluate a new project on 122nd Avenue in Portland, Oregon. 

The Bipartisan Infrastructure Law (BIL) established the "Safe Streets and Roads for All" program to provide $5-6 billion in funding to support regional, local, and Tribal initiatives to prevent roadway deaths and serious injuries. On Feb. 1, 2023, U.S. Transportation Secretary Pete Buttigieg announced $800 million in grant awards for 510 communities through the first round of funding for the Safe Streets and Roads for All (SS4A) grant program. 

See the full list of awarded projects here.

PBOT was awarded $20 million to make 122nd Avenue safer for all road users, and around $250,000 of that will go toward a research project to evaluate the effectiveness of the new safety treatments. The project will employ low-cost, high-benefit treatments on 5.5 miles of 122nd Avenue in...

The National Institute for Transportation and Communities (NITC) is proud to introduce our newest Dissertation Fellow, Nicholas Puczkowskyj of Portland State University, who was awarded $15,000 for his doctoral research project: Expanding Transmobilities: An Art-Informed Methodology For Genderdiverse Travel Behavior.

"My dissertation focuses on understanding how genderdiverse individuals' gender identity influences their travel behavior and travel decisions. I use an art-based methodology by operationalizing collage and mental maps to delicately capture these data. I believe this work will support mobility justice research and the greater social justice movement by further solidifying the field of transmobilities. Additionally, this research seeks to push the boundaries of transportation research by illustrating the power of art as a modality for travel behavior research," Puczkowskyj said.

There is a significant gendered travel behavior research gap in the transportation literature. A plethora of transportation literature identifying and contrasting cisgender disparities exists, but more inclusive approaches to genderdiverse identities remain scarce. The burgeoning field of transmobilities investigates transgender mobility and evolved from the nexus of mobility justice and gender studies by studying transgender experiences on public transit.

Research by the Oregon State University College of Engineering and Portland State University suggests a trio of roadway treatments would enable people age 65 and older to travel on foot more safely.

The research findings are important because older pedestrians are among the most likely to be killed in traffic accidents, according to the National Safety Council. In the United States in 2020 there were 709 pedestrian fatalities in the 65-74 age group – 20% of total road-user deaths in that age bracket. The project used data from Oregon collisions but is likely applicable in other areas, and it provides a framework for jurisdictions to develop their own safety recommendations, said David Hurwitz of the OSU College of Engineering.

Findings of the study led by Chris Monsere of Portland State were published in the Transportation Research Record in May 2022, "Systemic Opportunities to Improve Older Pedestrian Safety: Merging Crash Data Analysis and a Stakeholder Workshop".

Hurwitz and Monsere, whose collaborative background includes a recent...
