Cities around the world are improving upon the classic crosswalk. In Ahmedabad, India and Medford, Massachusetts, drivers are now confronted with 3D crosswalks painted on the asphalt. As Londonist reports, North London—home to perhaps the most iconic zebra crossing of all time—is the latest place to experiment with the new design.

The innovative crosswalks use an optical illusion to make roads safer for pedestrians. Instead of showing conventional flat stripes, the blocks in these crossings are painted with additional, shaded shapes around them, giving them the appearance of 3D objects raised from the ground.

The change is meant to get drivers' attention and encourage them to slow down before they reach the pedestrian crossing. Installing 3D crosswalks is a cheap and simple improvement, and it can potentially save lives.

The new crosswalk outside Barrow Hill Junior School in North London's St. John's Wood neighborhood uses this same trick. It's located around the corner from the place where The Beatles's Abbey Road album cover was shot. That's one crosswalk that likely won't be redesigned anytime soon, but luckily the hordes of tourists taking pictures there makes it easy to spot.

The new crosswalk is the first of its kind in the UK. After a nine- to 12-month trial run, London will consider installing the safety feature throughout the borough of Westminster.
