Assessment of a Drowsy Driver Warning System for Heavy-Vehicle Drivers: Final Report
Summary Information
Drowsiness is a known contributor to commercial vehicle crashes. It is estimated that driver drowsiness is a primary contributing factor in approximately 750 deaths and over 20,000 injuries involving commercial motor vehicles. A field operational test of an early prototype Drowsy Driver Warning System (DDWS) was conducted by the National Highway Traffic Administration and the Federal Motor Carrier Safety Administration. The data set consisted of 102 drivers from three for-hire trucking fleets using 46 instrumented trucks. Fifty-seven drivers were line-haul and 45 were long-haul operators.
Findings
The analysis revealed that drivers in the Test Group had a lower percentage of eye-closures (PERCLOS) values overall as compared to other experimental conditions. These results suggest that providing the driver with feedback as to his or her level of arousal would lead to an overall reduction of instances of drowsy driving.
