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. [1] [2]
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 ...
The HOS's main purpose is to prevent accidents caused by driver fatigue. This is accomplished by limiting the number of driving hours per day, and the number of driving and working hours per week. Fatigue is also prevented by keeping drivers on a 21- to 24-hour schedule, maintaining a natural sleep/wake cycle (or circadian rhythm). Drivers are ...
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 old road-safety paradigm of purely crash risk is a far more complex matter. Contributing factors to highway crashes may be related to the driver (such as driver error, illness, or fatigue), the vehicle (brake, steering, or throttle failures), or the road itself (lack of sight distance, poor roadside clear- zones, etc.).
Workers in the construction industry can be exposed to many ergonomic hazards. Construction work can involve floor and ground-level work, overhead work, hand-intensive work, and lifting, holding, and handling materials. [16] It is reported that back injuries in US construction were 50% higher than the average for all other US industries. [16]
Construction site safety is an aspect of construction-related activities concerned with protecting construction site workers and others from death, injury, disease or other health-related risks. Construction is an often hazardous, predominantly land-based activity where site workers may be exposed to various risks, some of which remain ...
Good ride quality provides comfort for the people inside the car, minimises damage to cargo and can reduce driver fatigue on long journeys in uncomfortable vehicles, [5] [6] and also because road disruption can impact the driver's ability to control the vehicle.
