Split Sleeper Berth Study Planned
Will Test Increased HOS Flexibility
The Federal Motor Carrier Safety Administration (FMCSA) has announced plans to conduct a test of the safety impact of allowing more flexible sleeper berth splits. The agency hopes to award the contract for the study this month. However, the study probably won’t actually begin to collect data until January, 2016, which puts any announcement of results at least two years away.
The study will allow 200 test drivers to utilize different scenarios in the way sleeper berth time is accumulated including extending the 14 hour clock. In some ways the tested scenarios will mirror rest strategies that were allowable prior to implementation of the current HOS regulations.
Testing will take place under actual driving conditions and the driver’s performance will be tracked using on-board monitoring systems. Also, the drivers will be required to periodically perform a three-minute psycho-motor vigilance test with the results uploaded via a smart phone app.
The ultimate goal is to determine if rest period flexibility will result in reduced driver fatigue. It’s interesting to note that a prior FMCSA study found that a split sleep schedule allowed drivers to get more rest as opposed to an entirely daytime sleep schedule.
In this study, drivers who slept at night got the most rest: 8.4 hours on average. Drivers who slept during the day got the least rest: 6.4 hours on average. Drivers who slept on a schedule split between day and night averaged 7.2 hours of rest. The study concluded that a single period of nighttime sleep is the most beneficial, but if drivers are unable to adhere to that schedule, the second-best alternative is a split sleep schedule.
