Believe it or not, optical illusion(视觉错觉) cut high way accidents.

Japan is a case in point. It has reduced traffic accidents on some roads by nearly 75%, using a simple optical illusion. Bent 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 of stripes on selected roads around the country to test how well the patterns reduce highway accidents.

  Over speeding plays a major role in as much as one fifth of all fatal 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, 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 really are, but also make a lane(车道) appear to be narrower. The result is a longer lasting reduction(减少) in highway speed and the number of traffic accidents.

The story of the Kennedy brothers is rather like one of those songs which children sing happily and which end up with the shout, “And then there none.”

The eldest brother was killed in the war, John was shot in Dallas in 1963, Robert was murdered in 1968, and Edward’s chances of becoming president may have died when his car had an accident, killing the passenger.

The four boys were brought up by their father to do and fight for nothing but the best, whether on the games field or in political life.  He managed to give them so much ambition(雄心) and energy that only since the youngest brother found his political death, have people begun to ask themselves, “Why did we look on the Kennedys as the family chosen to lead the USA to a better future?”

In fact, John and Robert had both shown their ability and courage in international politics and their work for civil rights, and Edward had a good record as senator(上议员); but so had many other people. Only history will show how much of the Kennedy story was built on fact and how much on the famous family name.
