Abstract:According to NHTSA’s National Center for Statistics and Analysis, drowsy driving was a contributing factor in 775 deaths in 2018, or 2.1% of total fatalities involving motor vehicle crashes on U.S. roadways. However, statistics, likely underestimate the extent of the drowsy driving problem. The American Automobile Association Foundation for Traffic Safety estimated the percentage of fatal crashes that involved a drowsy driver at 21%. This Research Note explores the feasibility of using machine learning algorithms to identify drowsy driving episodes in large-scale naturalistic driving datasets. The Strategic Highway Research Program 2 (SHRP2) Naturalistic Driving Study (NDS) collected data from more than 3,400 participating drivers in six States, yielding time series data for more than 5 million trips. The SHRP2 NDS database contains vehicle variables and video data, including a view of the driver’s face.
