Safety Impacts of Human- Automated Driving Systems Team Driving Applications (ADS-Teams)

The core mission of the Federal Motor Carrier Administration (FMCSA) is to reduce commercial motor vehicle (CMV) related crashes and fatalities. In carrying out its safety mission, and in accordance with 49 U.S.C. 504, 31133, 31136, 31502, 49 CFR 1.73, and 49 U.S.C. 31108, FMCSA conducts research to identify and assess contributing factors associated with CMV crashes and performs analyses to identify potential mitigation strategies that could be used to improve safety. To carry out these research studies, FMCSA contracted with the Virginia Tech Transportation Institute (VTTI) to quantify the safety implications of four use cases where human drivers team with a CMV equipped with an automated driving system (ADS). Specifically, FMCSA will use a literature review, interviews, and simulator testing to collect data on in-vehicle driver and remote driver workload, fatigue, alertness, and distraction when teaming with an ADS-equipped CMV. These data will provide support for the analysis of potential requests for Federal Motor Carrier Safety Regulation relief under 49 C.F.R. §381 (hours-of-service). This Privacy Impact Assessment (PIA) is being conducted to address the risks associated with VTTI collecting, processing, and maintaining Personally Identifiable Information (PII) from study participants on behalf of FMCSA.
