This webinar will present an open-source socio-transportation analytic toolbox (STAT) for public transit system planning. This webinar will consist of a demonstration of the STAT toolbox, for the primary purpose of getting feedback from transit agencies on the tool's usefulness. We are especially interested in hearing about any improvements that would aid transit agencies in implementing it.

The STAT toolbox was created in an effort to integrate social media and general transit feed specification (GTFS) data for transit agencies, to aid in evaluating and enhancing the performance of public transit systems. The toolbox enables the integration, analysis, and visualization of two major new open transportation data sources—social media and GTFS data—to support transit decision making. In this webinar, we will introduce how we leveraged machine learning and natural language processing techniques to retrieve Twitter data related to public transit systems and to extract sentence structures to geomap those tweets to their corresponding transit lines/stations. Combined with transit accessibility measures computed using GTFS, STAT is able to identify the mismatch between the services that the agency is providing and what the transit users are experiencing. The project uses Salt Lake City and Portland as case studies to demonstrate the usability of the toolbox and how it can support querying, navigating, and exploring the interactions between transit users and services.


  • Demonstration of the STAT Toolbox
  • Understand how to use the STAT Toolbox and its capabilities and limitations
  • Discover how you might implement the STAT toolbox at your agency


This webinar is based on a study funded by the National Institute for Transportation and Communities (NITC) and conducted at the University of Utah and Portland State University. Read more about the NITC research: Leveraging Twitter and Machine Learning for Real-Time Transit Network Evaluation.

This webinar is hosted by the Transportation Research and Education Center (TREC) at Portland State University. The research was funded by the National Institute for Transportation and Communities (NITC), a program of TREC and 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.
