Duration Restart Period Needed to Recycle with Optimal Performance: Phase II. Tech Brief

摘要

The objective of this Phase II project was to determine whether a restart period involving two biological nights of sleep would be more effective in restoring performance in individuals working night shifts under the hours of service (HOS) regulations governing property-carrying commercial motor vehicle (CMV) drivers than the current 34-hour restart provision. Building on the Phase I project, which evaluated the 34-hour restart using two groups of drivers, one operating in daylight and one at night, this new study with nocturnal duty periods and a restart period that includes two biological nights was undertaken using a within-subjects in laboratory experimental study design with testing of cognitive performance task and high-fidelity driving simulator performance.
