Driver Vigilance in Automated Vehicles: Investigating Hazard Detection Performance

Drivers of automated vehicles must be able to detect and respond to automation failures, which requires maintaining attention to the roadway for prolonged periods of time. Traditional vigilance tasks typically elicit a temporal decline in signal detection performance (Warm et al., 2015). Declines in detection performance may lead to the driver not responding to automation failures and potential collisions (NHTSA, 2017). Similarities between roadway monitoring during automation and traditional vigilance tasks warrant investigation into drivers’ ability to maintain vigilance for prolonged periods of time. The current study explored the possibility that a vigilance decrement would present itself in the form of a decline in drivers’ ability to detect roadway hazards.
