Believe it or not, optical 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 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 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 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. (227 words)
What does the author say about straight, horizontal bars painted across roads?
选项
A、They are falling out of use in the United States.
B、They tend to be ignored by drivers in a short period of time.
C、They are applicable only on broad roads.
D、They cannot be applied successfully to traffic circles.
答案
B
解析
本题属于细节判断题。根据题干的关键词“straight,horizontal bars”找到文中的描述句为“However,traffic often…to seeing the painted bars”,意思是几个月后人们又恢复到以全速开车,因为司机已习惯看到那些笔直的横线。由此可以选择选项B“人们很快就忽视了这种笔直的横线”。
