Fatigue can be both physical and mental. Physical fatigue is the inability to continue functioning at the level of one's normal abilities; a person with physical fatigue cannot lift as heavy a box or walk as far as he could if not fatigued. [3] [4] [5] Mental fatigue, on the other hand, rather manifests in sleepiness or slowness. A person with ...
Driver drowsiness detection is a car safety technology which helps prevent accidents caused by the driver getting drowsy. Various studies have suggested that around 20% of all road accidents are fatigue-related, up to 50% on certain roads.
The National Highway Traffic Safety Administration (NHTSA) has estimated that between the years 2011 and 2015, driver drowsiness was involved in approximately 1.4% of all car crashes reported to police in the United States, including 2.0% of crashes that resulted in injuries and 2.4% of crashes that resulted in a death.

Fatigue impacts a driver's reaction time, awareness of hazards around them and their attention. Drowsy drivers are three times more likely to be involved in a car crash, and being awake over 20 hours is the equivalent of driving with a blood-alcohol concentration level of 0.08%. [150]
Fatigue detection software analyse behaviour and warning signs to determine the onset of fatigue. The technology has the potential to be a highly accurate tool for detecting the early stages of fatigue in drivers and minimise the likelihood of incidents. The technology allows operators in real time to visually identify their levels of alertness.
The Artificial Passenger is equipped to engage a vehicle operator by carrying on conversations, playing verbal games, controlling the vehicle's stereo system, and so on. It also monitors the driver's speech patterns to detect fatigue, and in response can suggest that the driver take a break or get some sleep.
The ability to drive without intense concentration (e.g., on highways without intersections or traffic lights [9]) or with few cars on the road [7] It is suggested that highway hypnosis occurs more frequently in experienced drivers and on familiar road sections, as this allows for driving in an automatic mode.
In manual transmission cars, the dead pedal is designed to promote a smoother actuation of the clutch by keeping the driver's foot in the same plane as the pedal. [1] Automatic transmission cars can also benefit from the dead pedal because it prevents fatigue by offering a stable inclined surface on which the driver can place their foot. Even ...
