Believe or not, optical illusion(错觉)can cut highway crashes. Japan is a case in point. It has reduced automobile crashes to some roads by nearly 75 percent using a single optical illusion. But 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 crashes. Excessive(too great)speed 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 hazards(danger)are the greatest curves, exit slopes, traffic circles, and bridges.
Some studies suggest that straight, horizontal 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 appear to be narrower. The result is a longer lasting reduction in highway speed and the number of traffic accidents. [br] What does the author say about straight, horizontal bars painted across roads?
选项
A、They are suitable only on broad roads.
B、They are falling out of use in the United States.
C、They are ignored in a long period of time.
D、They cannot be used successfully to traffic circles.
答案
C
解析
语意释义题。第三段提到horizontal bars…initially…减少事故的发生,但是within months…drivers become used to。所以时间一久,就容易被司机忽视,即这些标记的警示效果不持久。
