Methodological Overview of the Drowsy Driver Warning System Field Operational Test

To address the issue of fatigued truck drivers, the U.S. Department of Transportation sponsored research to develop a Drowsy Driver Warning System. This system has been under development for several years and is at a point where it is ready for a Field Operational Test. The experimental plan calls for 102 drivers, each operating one of 34 instrumented heavy trucks for 16 weeks. Each vehicle is instrumented with video cameras and a variety of sensors to capture driver input/performance. This paper describes the method being used to conduct the study, including an overview of the data collection instrumentation.
