Human Factor in ADS-equipped Commercial Motor Vehicles

Project Goal:

The objective of the project is to conduct research on human factors related to automated driving systems (ADS)- equipped commercial motor vehicles (CMVs).


FMCSA completed the study “Driver Limitations in Automated-Driving-System-Equipped Commercial Motor Vehicles: An Analysis of Research Gaps” (in press). A detailed literature review was conducted; ongoing, relevant research was compiled; and research needs were identified. Overall, the project found that there was little research effort being undertaken specifically related to ADS-equipped CMVs. Much of the work related to ADS technology was related to passenger vehicles. The report provides recommendations for safe and effective use of ADS-equipped CMVs on U.S. roadways.


This study is a truck simulator study of CMV drivers regarding the use of ADS-equipped CMVs, specifically SAE Level 3 and Level 4 vehicles. Scenarios will be developed to address the research questions related to distraction, readiness, and transfer of control.
