Our History at Portland State University

As Oregon's only urban public global research university, Portland State University offers tremendous opportunity to nearly 28,000 students from all backgrounds. Our mission to "Let Knowledge Serve the City" reflects our dedication to finding creative, sustainable solutions to local and global problems. In 1966, Dr. Walter H. Kramer founded the first transportation studies center in the Department of Marketing. After decades of investment in PSU's transportation studies, our faculty and staff expertise earned PSU a USDOT-funded a regional university transportation center (UTC) from 2006 - 2014. We have successfully competed for more federal grants and currently lead the National Institute for Transportation and Communities program– one of seven national university transportation centers. Our center and staff have grown far beyond the initial UTC grants, and now encompass a wide variety of programs.
