This webinar will present an open-source socio-transportation analytic (STAT) toolbox for public transit system planning, in an effort to integrate social media and general transit feed specification (GTFS) data for transit agencies 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: 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 that are related to public transit system and to extract sentence structures to geomap those tweets to their corresponding transit lines/stations. Combining with transit accessibility measures computed using GTFS, STAT is able to identify the mismatch between the services that the agency is providing versus 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.
