On Apr. 23, 2020, Dr. Sherry discussed the research findings of MPC-409, the measurement issues and fatigue management in the transportation industry. The purpose of this project was to establish a baseline for the evaluation of proposed fatigue mitigation efforts, utilizing a variety of measures of sleep and fatigue, to gather initial data for comparison to later studies. Results demonstrated that there was sufficient data to establish a baseline for evaluate existing work schedules using the fatigue models approved by the FRA. The results indicate that typical day-time schedules have the least risk of fatigue. Standard night shifts, from 11 pm to 6 am had the greatest risk of fatigue.
