Believe it or not，optical illusion（视觉错觉），can cut highway accidents.Japan is a case in point.It has reduced car accidents on some roads by nearly 75 percent using a simple optical illusion.4T6e,L1]2F5~
Bent stripes，called chevrons（人字型）painted on the roads made 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.High speed plays a major role in as much as one fifth of all deadly traffic accidents，according to the foundation.To help reduce those accidents，the foundation will carry out its tests in areas where speed related dangers are the greatest curves，exit slopes（斜坡），traffic circles，and bridges.Some studies suggest that straight，horizontal（水平的）bars painted across roads can 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 road appear to be narrower.The result is a longer lasting reduction in highway speed and the number of traffic accidents.4T6e,L1]2F5~
