Mercedes estate cars and Fiat runarounds are being used to test up to 22 different monitors designed to detect if a driver is falling asleep at the wheel and trigger a series of devices designed to wake them up.
The aim of the project, funded by £4 million of European Union money as well as private investment, is to reduce the estimated 30% of fatal accidentswhich are caused in Europe each year by drivers drifting off at the wheel. The test cars have been fitted with infrared cameras which monitor eye movement, touch-pad sensors that measure the driver’s grip on the steering wheel and chassis monitors which check for veer. Should drivers start to doze off they can be quickly woken by a sudden blast of air-conditioned cold air. At the same time a vibrating alarm will sound and the driver’s seat will be made to shake.
Daimler Chrysler, owner of Mercedes, as well as Fiat, will own the patent of the awake system,which could be installed in cars as soon as this year. If the trials are successful the EU is considering introducing a directive which would make the system compulsory in long-distance lorries—a leading cause of road accidents.
According to transport department figures, more than 300 people die each year in Britain in accidents thought to be caused by drivers falling asleep at the wheel. Ten people died in the Selby rail crash last year when a car driver fell asleep on a motor-way, crashed onto a railway line and derailed a passenger train. Motoring organizations said the new system might prevent accidents such as Selby but were cautious as to whether it would prove practical.
The safety system also monitors braking frequency and can detect eye movement towards the rear and side mirrors. As no one drives in exactly the same way, the system must "learn" the individual characteristics of its owner or owners.
The researchers had considered systems that squirted a refined version of smelling salts at the dozy motorist, opened the windows and activated the brakes automatically. However, such ideas have been abandoned as potentially dangerous, startling a driver and leading to sudden changes in steering.
The author may agree that the Selby crash _____.
选项
A、triggered the development of the awake system
B、happened because the train driver drifted off at the wheel
C、highlighted the advantages of installing the awake system
D、caused researchers’ concern about the practicality of the awake system
答案
C
解析
事实细节题。根据题干中的Selby crash可定位至第四段。本文介绍了唤醒系统的研发,结合第四段最后一句可以知道,作者提到塞尔比铁路撞车事故是为了表明唤醒系统可以避免这种事故的发生,即它的好处,由此可见,C项为本题答案。
