An Electronic Logging Device (ELD) is a piece of hardware that automatically records a commercial motor vehicle (CMV) driver’s driving time and automatically maintains their hours-of-service (HOS) records. Mandated by the Federal Motor Carrier Safety Administration (FMCSA), ELDs are required for most motor carriers and drivers, including commercial buses, all of whom are required to maintain a log to record their HOS, files otherwise known as Records of Duty Status (RODS) 2018. Intended to promote driver safety and ensure compliance with regulations, an ELD automatically records a driver’s RODS, eliminating the need for manual paper logs and promoting easier, more accurate HOS recordkeeping. These records, which form a type of probe data, are conceptually rich with information for transportation planners.
