Japan is case in point. It has reduced automobile crashes on 41 ______.
some roads by nearly 75 percent using a simple optical illusion.
Bending stripes, called chevrons (人字形), painted on the roads make 42 ______.
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 the patterns reduce 43 ______.
highway crashes.
Excess speed plays a major role in as much as one fifth of all 44 ______.
fatal traffic accidents, according to the foundation. To help reduce those
accidents, the foundation will conduct its tests in areas which speed-related 45 ______.
