Zebra crossings - the alternating dark and light stripes on the road surface - are meant t。

remind drivers that pedestrians may be trying to get across. Unfortunately, they are not very

effective. A 1998 study done by the Department of Traffic Planning and Engineering at Sweden's

Lund Univers ity revealed that three out of four drivers maintained the same speed or even speeded up as they were approaching a crossing. Even worse? Only 5% stopped even when they saw someone trying to get across.

Now a mother-daughter team in Ahmedabad, India has come up with a clever way to get

drivers to pay more attention - A 3-D zebra crossing with an optical illusion (视错觉) .

Artists Saumya Pandya Thakkar and Shakuntala Pandya were asked to paint the crosswalks by IL&FS, an Indian company that manages the highways in Ahmedabad. The corporation was looking for a creative solution to help the city's residents to cross the busy accident-prone (易出事故的) roads safely. Thakkar and Pandya, who had previously seen images of3-D zebra crossings that gave drivers the illusion of logs(原木)of wood on the streets in Taizhou, China, decided to test if a similar way would work in India.

Sure enough, in the six months that the 3-D crosswalks have been painted across four of the city's most dangerous highways, there have been no accidents reported! The artists say that while it may appear that the zebra crossing could cause the drivers to brake suddenly and endanger the vehicles behind, such is not the case. Because of the way the human eye works, the illusion is only visible from a distance. As they get closer, the painting looks just like any other ordinary zebra

crossing. The creators hope that their smart design will become increasingly common throughout

India and perhaps even the world. So let's look for ward to it.
