For the project “Data Analytics and Modeling Methods for Tracking and Predicting Origin-Destination Travel Trends Based on Mobile Device Data,” the Maryland Transportation Institute (MTI) at the University of Maryland worked with data provider partners such as mobile phone companies to determine if accurate and reliable origin-destination (OD) products could be developed from mobile device location data. The team was dedicated to developing transparent evaluation and open-source algorithms that can build more public trust toward the data and relevant products and get the research community more involved in the new technology. The Federal Highway Administration’s (FHWA) Exploratory Advanced Research (EAR) Program funded the study.
