Believe it or not, optical illusion(视觉错觉)can cut highway accidents.

  Japan is a case in point. It has reduced traffic accidents on some roads by nearly 75 percent using a simple optical illusion. Bent(弯曲的) stripes, called chevrons(人字形),painted on the roads make drivers think that they are driving faster than they really are, and thus drivers slow down.

  Now the American Automobile Association Foundation for Traffic Safety in Washington D.C. is planning to repeat Japan’s success. Starting next year, the Foundation will paint chevrons and other patterns(样式) of stripes on certain roads around the country to test how well the patterns reduce highway accidents.

  Overspeeding plays a major role in as much as one fifth of all fatal(致命的) traffic accidents, according to the Foundation. To help reduce those accidents, the Foundation will conduct its tests in areas where speed-related dangers are the greatest-curves, exit slopes, traffic circles, and bridges.

  Some studies suggest that straight(直的), horizontal(平行的)bars painted across roads can initially cut the average speed of drivers in half. However, traffic often returns to full speed within months as drivers become used to seeing the painted bars.

  Chevrons, scientists say, not only give drivers the impression that they are driving faster than they really are but also make a lane(车道) appear to be narrower(狭窄的). The result is a longer lasting reducing in highway speed and the number of traffic accidents.

　　 Believe it or not, optical(视觉的) illusion(错觉) can cut highway crashes. Japan is a case in point. It has reduced automobile crashes on some roads by nearly 75 percent using a simple optical illusion. Bent strips(带状物), called chevrons(人字形), painted on the roads make drivers think that they are driving faster than they really are, and thus drivers slow down.

Now the American Automobile Association Foundation for Traffic Safety in Washington D.C. is planning to repeat Japan’s success. Starting next year, the foundation will paint chevrons and other patterns of strips on selected roads around the country to test how well the patterns reduce highway crashes.

Excessive(极度的) speed plays a major role as much as one fifth of all fatal(致命的) traffic accidents, according to the foundation. To help reduce those accidents, the foundation will conduct its tests in areas where speed-related hazards(危险) are the greatest ---- curves, exit slopes, traffic circles, and bridges.

Some studies suggest that straight, horizontal(水平的) bars painted across roads can initially(最初) cut the average speed of drivers in half. However, traffic often returns to full speed within months as drivers become used to seeing the painted bar.

Chevrons, scientists say, not only give drivers the impression that they are driving faster than they are but also make a lane look narrower. The result is a longer reduction in highway speed and the number of traffic accidents.
