Researchers engaged two transit agencies, the Utah Transit Authority (UTA) and TriMet, to test the usability of the toolbox. Salt Lake City, Utah and Portland, Oregon were used as case studies in the platform for querying, navigating and exploring the interactions between transit users and services. Leveraging machine learning and natural language processing techniques, the team retrieved Twitter data that are related to public transit systems and extracted sentence structures to geomap those tweets to their corresponding transit lines/stations.

Research and Events
July 2019
Last Call for Early Bird Registration to the 2019 Transportation & Communities Summit
Early Bird registration ends on Monday, July 15 for the 11th annual Transportation and Communities Summit, taking place September 19–20 at Portland State University. The program continues to evolve as we add more voices to the table, so check out the sessions and workshops and see what's new. This event connects national mobility-focused research to equitable practice and policy through breakout panels, Lightning Talks, student posters, skill-building workshops, and—this year—a keynote from urban data scientist Ben Wellington, founder of I Quant NY. Register now to gain discounted access to the Pacific Northwest's premiere transportation conference.
Leveraging Twitter and Machine Learning for Real-Time Transit Network Evaluation
With today's profusion of open data sources and real-time feeds, transit agencies have an unparalleled opportunity to leverage large amounts of data to improve transit service. Thanks to NITC researchers, there is now an open-source tool for that. The new Social-Transportation Analytic Toolbox (STAT) for Transit Networks, developed by researchers at the University of Utah and Portland State University, is a dynamic platform that combines Twitter, general transit feed specification (GTFS), and census transportation planning products (CTPP)—in this case, job density data—to help agencies evaluate overall system performance and identify connectivity gaps.
Over $1M in Research Funding for New Projects on Micromobility, TOD’s, and Equity in Transportation Access
The NITC research consortium has awarded $1+ million in funding for ten research projects spanning five universities. This year we focused funding on micromobility, multimodal traffic, meeting the transportation needs of underserved populations and people with disabilities, and exploring the intersection of transportation and housing. The next NITC Small Starts research grant funding opportunity will open on July 15 and is open to faculty at Portland State University, the University of Oregon, Oregon Institute of Technology, University of Utah, University of Arizona and University of Texas at Arlington.
The Advantages and Limitations of Land Use Codes for Multifamily Housing Trip Generation
Many cities are reconsidering their reliance on ITE's Trip Generation Manual. Kelly Clifton of Portland State University is one of the researchers leading the charge to identify a more nuanced approach to anticipating transportation demand; especially person (non-car) trips. In an extended series of TREC projects, Clifton has collaborated on creating a more holistic approach to trip generation, particularly useful in urban areas with a greater mix of land uses. In the latest report to come out of these efforts, Clifton and co-investigator Kristina Currans of the University of Arizona examine the advantages and limitations of ITE's land use taxonomy for multifamily residences.
Student Spotlight: Darshan Chauhan, Portland State University
Darshan is a graduate research assistant in civil engineering at Portland State University. He currently serves as PSU's treasurer of STEP (Students in Transportation Engineering and Planning), and in the 2018/2019 academic year he earned a Walter H. Kramer Fellowship from PSU. For TRB this year, he worked on determining drone launching sites to supply critical supplies (like blood, medicines) in post-disaster scenarios. He will defend his masters thesis on network flow problems this year. He plans to continue on to his PhD after earning his masters, and eventually sees himself working as a professor at a research-intensive university.

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