Tiredness kills

This article looks at UK-developed devices to warn drivers of their own fatigue or of obstacles or hazards ahead. Anti-fatigue devices can be divided into two groups: some monitor the driver for signs of fatigue, others the movement of the car. One device is a wrist-worn monitor which vibrates if the user does not move for 15 seconds while driving. A problem with monitoring only certain signals of tiredness is that people show different characteristics when falling asleep; a danger with alert devices needing reaction tasks is that the driver's attention is distracted from the road. The movement of the vehicle is a more reliable indicator of driver fatigue: monitoring devices include multifunction radar and communications sensors. Further developments of this technology would allow car-to-car and roadside-to-car transmission of warning information on hazards ahead. (A)
