TREC Webinar Series

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. TREC is home to the U.S. DOT funded National Institute for Transportation and Communities (NITC) consortium, the Initiative for Bicycle and Pedestrian Innovation (IBPI), and other transportation grants and programs. We produce impactful research for transportation decision makers, and support the education of future transportation professionals through curriculum development and student participation in research.
