     A device that stops drivers from falling asleep at the wheel is about to undergo testing at Department

of Transport laboratories and could go on sale within 12 months. The system, called driver Alert, aims to

reduce deadly road accidents by 20%-40% that are caused by tiredness. Airline pilots can also use it to

reduce the 30% of all pilot-error accidents that are related to fatigue.

    Driver Alert is based on a computerized wristband. The device, worn by drivers or pilots gives out a

sound about every four minutes during a car journey. After each sound the driver must respond by squeezing

the steering wheel (方向盘). A sensor in the wristband detects this pressing action and measures the time

between the sound and the driver's response.

    Tiredness is directly related to a driver's response time. Usually, a watchful driver would take about 400

milliseconds to respond, but once that falls to more than 500 milliseconds, it suggests that the driver is getting

sleepy.

    In such cases the device gives out more regular and louder sounds, showing that the driver should open a

window or stop for a rest. If the driver's response continues to slow down, the sounds become more frequent

until a nonstop alarm warms that the driver must stop as soon as possible.

     The device has been delivered to the department's laboratories for testing. If these tests, scheduled for six

months' time, are successful, the markers will bring the product to market within about a year.
