　　Believe it or not, optical illusion 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 , 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.
