Overview

As part of the Federal Motor Carrier Safety Administration (FMCSA) mandated “Investigation
into Motor Carrier Practices to Achieve Optimal Commercial Motor Vehicle (CMV) Driver
Performance” Indefinite Date/Indefinite Quantity(IDIQ) Research and Technology Program, a
laboratory study was conducted between February 2010 and April2011 to examine the effect of
split sleep versusconsolidated sleep on human performance and long-term health-related
parameters.This technical report presents the design, methods, research findings, and
conclusions of this study.
The study compares the effects of consolidated nighttime sleep, split sleep, and consolidated
daytime sleep on total sleep time, performance, participant subjective state, and biomedical
parameters. It appears that if consolidated nighttime sleep is not possible, then split sleep is
preferable to consolidated daytime sleep. This conclusion is based on the findings of relatively
less total sleep time and greater subjective sleepinessin the daytime sleep condition compared to
the split sleep and consolidated nighttime sleep conditions. Performance was equivalent across
all three of the sleep conditions in the present study. Further, there were some changes in
biomedical parameters associated with the different sleep conditions.
This technical report may be of value to anyone interested in fatigue and its management in
CMVoperations and other modes of transportation.
