With the high costs associated with primary data collection, methods to improve the use and accessibility of newer sources of data such as Global Positioning System (GPS) data can benefit many transportation practitioners. GPS data can have multiple uses beyond traditional applications such as estimates of speed and travel times. GPS-related data that have been collected from automatic vehicle location systems, from highway sensors, as supplemental information to traditional travel surveys, and via passive technologies [e.g., Bluetooth, radio frequency identification (RFID), and smartphones] have shown promise for additional planning purposes. Some challenges to increased use of GPS data include addressing data bias; balancing precision, coverage, and confidentiality; resolving institutional issues such as data ownership; and addressing the complexity of combining these data with other sources to discern behavioral relationships. This report provides guidelines on the use of multiple sources of GPS data to understand travel behavior and activity. The guidelines are intended to provide a jump-start for processing GPS data for travel behavior purposes and provide key information elements that practitioners should consider when using GPS data. The report is structured in two volumes. Volume 1 presents the methods used and results of tests conducted. Volume II translates the results of the tests conducted into guidelines for planners and researchers to implement these procedures.
