Who We Are

29131568506_a957299dca_o.jpg

We inform transportation decision making through primary research, building the capacity of the transportation workforce, supporting the education of future transportation professionals, and engaging students in research. 

The Transportation Research and Education Center (TREC) at Portland State University (PSU) is first and foremost an interdisciplinary center. Our research initiatives pull together the voices and expertise of a wide range of backgrounds that collectively shape the ways we move through the world. We support collaborative research and education that provide a unique lens on transportation insight for vibrant communities.

We manage a multitude of programs, grants, and projects - including:

  • As the campus-wide transportation center, we provide education and collaborative research opportunities that improve mobility on campus, in the City of Portland, and the greater Metro region. Notably, we have been hosting free, weekly Friday Transportation Seminars for the public since 2000.

  • We are the lead campus of the National Institute for Transportation and Communities (NITC) — one of five University Transportation Centers (UTC's) funded by the U.S. Department of Transportation’s (learn more about the grant here). We pursue our theme, improving mobility of people and goods to build strong communities, through research, education and technology transfer in conjunction with our partner universities: University of Oregon, Oregon Institute of Technology, University of Utah and new partners University of Arizona and University of Texas at Arlington.

  • The Initiative for Bicycle and Pedestrian Innovation (IBPI), which shares active transportation insight with professionals and educators through training opportunities, conferences and outreach.

Our History

Our faculty expertise in innovative transportation research and education earned Portland State a federally funded university transportation center in 2006. That grant, named OTREC, ran through 2014. Portland State used its success in running the OTREC grant program to successfully compete for a second U.S. Department of Transportation grant that became the NITC program. That program was later extended and renewed, with the center competing successfully to be designated one of U.S. DOT's five national university transportation centers.

Friday Transportation Seminar: Karl Miller Center at PSU, 615 SW Harrison St., Room 465

Detailed directions to the Friday Transportation Seminar for blind or visually impaired visitors:

The Harrison Street entrance to the Karl Miller Center is between 6th and Broadway on the north side of Harrison. Walking west from 6th Avenue, the entrance to the building will be on your right, about ten paces from the edge of the building or about 16 steps from the textured curb cut on the street corner. There are two shallow steps to your right, leading down to the glass double doors. Once you're inside, you'll be facing a big open lobby area. The floor slopes down slightly, and there's a hand rail on the wall to your right. When you get to the end of the hand rail, keep walking in the same direction it was leading as if it continued in a perfectly straight line, and you should arrive at the opposite wall where there's another hand rail. (The room has two tables and two support columns to navigate around). Once you get to the other side of the lobby, if you come to a set of glass doors instead of a plain wall, then you're too far to the right. You need to follow the wall to your left until you reach the next hand rail. This rail will lead you to the elevators, which are on the same side of the wall as the hand rail. Since you're on the ground floor there's only one button. On the 4th floor, you'll step out of the elevator and turn right. The room you're facing now is room 470; it's about 12-15 steps directly in front of you. There's usually a round table and chairs sitting by the wall in the hallway on the left side of room 470. Room 465 (where the seminar takes place) is the next room to the left, just past this table and chairs.
