Understanding Limitations for Drivers of ADS-Equipped CMVs

Project Goal:

To develop an understanding of human factors challenges for automated commercial motor vehicle (CMV) applications.


As the Federal Motor Carrier Safety Administration (FMCSA) begins to consider the use of automation by commercial drivers, it will be critical to understand the parameters under which these systems can be used safely in light of human factors limitations.


This project will help the Agency develop an understanding of human factors challenges for automated CMV applications. Tasks include a comprehensive literature review and simulator studies. Findings will inform future research efforts, including potential pilot projects. Researchers will seek to: determine measures of situational awareness and alertness when using Level 1 and 2 systems; develop strategies for regaining situational awareness when re-engaging in the dynamic driving task; develop recommendations for mitigating the impacts of visual and cognitive distractions on situation awareness and vigilance when using Level 2 and 3 systems; and assess the degradation of skills as drivers rely upon automation (particularly Level 3).
