Transportation decision-makers typically use benefit-cost analysis (BCA) to evaluate the tradeoffs of transportation projects. However, it is difficult to produce state-specific measures that are multimodal and can consistently evaluate the full range of public and private benefits and costs for… Read More

This applied research project aims to adapt and further train YOLOv9 to enhance its ability to accurately detect, track, and count cyclists and pedestrians in video data from the Portland Metro Area. The method will also extract surrogate safety metrics, such as Post Encroachment Time, which are… Read More

Counts provide the foundation for measuring nonmotorized travel along a link or a network and are also useful for monitoring trends, planning new infrastructure, and for conducting safety, health, and economic analyses. Most agencies still use manual counting methods, however over the last decade,… Read More

Researchers will conduct an evaluation of the Better Bike Share Partnership (BBSP) Living Lab. BBSP provided five organizations in Detroit, Chicago, Cincinnati, Portland and Philadelphia with funding, support and resources to develop best practices addressing significant barriers to shared… Read More

This project is led by the Transportation Research and Education Center (TREC) at Portland State University (PSU), in collaboration with the Institute for Tribal Government (ITG) at PSU, Toole Design Group, the Highway Safety Research Center at University of North Carolina (UNC-HSRC), Sheri Bozic … Read More

The need for improving active transportation safety and mobility is clear, as the share of all road user deaths that are pedestrians or cyclists has risen nationally. The US Department of Transportation (US DOT), along with state DOTs across the nation, have made addressing this safety challenge a… Read More

Current fatality and serious injury trends continue to rise steeply for all road users, particularly vulnerable users, in both Washington State specifically and across the United States more broadly. While the United States Department of Transportation has formally adopted the Safe System Approach… Read More

Photo by Jonathan Maus, BikePortland The trip to and from school is made by nearly every child in Oregon every school day. Bike and walk buses, or organized groups of school children, parents, and ride/walk leaders, seek to encourage biking and walking to school. Aside from mitigating some of… Read More

The American Association of State Highway Transportation (AASHTO) Strategic Plan includes a goal of promoting diversity in all AASHTO activities, collaborating with traditional and nontraditional partners to support equity and social justice objectives, and ensuring that transportation policies… Read More

The objective is to address practical challenges related to mobility and accessibility following natural disasters. The anticipated outcome of this project will be to provide actionable insights and solutions that can be implemented in real-world transportation systems. By leveraging the available… Read More

The last decade saw double-digit growth of e-commerce sales, both in the US and Oregon, which translates to more delivery vehicles on the roads to meet this demand. However, there is no observed data available to determine the net impacts on system use for this rapidly expanding sector. It is… Read More

Critical transportation infrastructure in Washington and Oregon is vulnerable to damage during strong earthquake shaking, including the anticipated magnitude 9 Cascadia Subduction Zone event. A major hazard to transportation infrastructure is the failure and deformation of the underlying soil… Read More
