In 2021 we embarked on creating NITC Research Roadmaps across six core transportation areas of our work, each aimed at identifying key gaps to guide the future direction of research and workforce development initiatives. But to look forward, we had to look back first. This summer, we're be releasing literature reviews of a decade of NITC research in key topic areas. We started with Transportation and Land Use, and now we're moving on to the next theme: Multimodal Data and Modeling.

Multimodal transportation systems are the backbone of U.S. economic activity. An in-depth understanding of multimodal travel, through data collection and modeling strategies, is crucial to inform policy.

Authored by Sirisha Kothuri and Liming Wang of Portland State University, Kate Hyun of the University of Texas at Arlington, Thomas Gotschi of the University of Oregon, Cathy Liu of the University of Utah, Abolfazl Karimpour of the University of Arizona, and Abbas Rashidi of the University of Utah, this literature review explores NITC's contributions in advancing the state of the practice in this field.

The National Institute for Transportation and Communities (NITC) is one of seven U.S. Department of Transportation national university transportation centers. NITC is a program of the Transportation Research and Education Center (TREC) at Portland State University. This PSU-led research partnership also includes the Oregon Institute of Technology, University of Arizona, University of Oregon, University of Texas at Arlington and University of Utah. We pursue our theme — improving mobility of people and goods to build strong communities — through research, education and technology transfer.
