Painted optical illusion road blocks trick drivers into slowing down near school zones in India

Optical illusion paintings on roads slow dangerous traffic

Speed bumps and zebra crossings aim to slow down road traffic, but that doesn’t mean every driver obeys those kinds of road warnings. That’s why the city of Ahmedabad, India took painted road instructions a step further, and created optical illusions that look like three-dimensional road blocks when approached from the right angle.

A highway management company in Ahmedabad commissioned local artists Saumya Pandya Thakkar and Shakuntala Pandya to paint the optical illusion crosswalks in school zones. “A lot of school kids were crossing the road, and it was not safe for them because of the high speed of the highway,” said Thakkar. Drawing inspiration from similar crosswalk illusions that had been painted in China, the duo painted a total of four highway crosswalks in Ahmedabad’s school zones.

Since completing the project in January, Ahmedabad highway officials have reported that accidents have been eliminated in those four dangerous traffic areas. The illusion is effective because at a distance, drivers’ eyes are tricked into believing there is a three-dimensional roadblock in the middle of the highway. After slowing down on approach, drivers can clearly see that the blockage is an optical illusion as they near the painting, so they don’t brake completely or stop the flow of traffic.

If anything else, getting drivers to pay attention to their speeds in active school zones has had a positive impact. “It’s not that dangerous for the drivers, because they can make out that this is just a painting. But the idea is that they pay attention because of the new creations,” said Thakkar. And for any driver with a sense of humor, the optical illusions might even send them on their day with smiles on their faces.

There's a scene in Mission Impossible 3 that you might recall. In it, our hero Ethan Hunt (Tom Cruise) tackles the movie's villain, holds him at gunpoint, and forces him to read a bizarre series of sentences aloud.

"The pleasure of Busby's company is what I most enjoy," he reluctantly reads. "He put a tack on Miss Yancy's chair, and she called him a horrible boy. At the end of the month, he was flinging two kittens across the width of the room ..."

Digital Trends’ Top Tech of CES 2023 Awards
Best of CES 2023 Awards Our Top Tech from the Show Feature

Let there be no doubt: CES isn’t just alive in 2023; it’s thriving. Take one glance at the taxi gridlock outside the Las Vegas Convention Center and it’s evident that two quiet COVID years didn’t kill the world’s desire for an overcrowded in-person tech extravaganza -- they just built up a ravenous demand.

From VR to AI, eVTOLs and QD-OLED, the acronyms were flying and fresh technologies populated every corner of the show floor, and even the parking lot. So naturally, we poked, prodded, and tried on everything we could. They weren’t all revolutionary. But they didn’t have to be. We’ve watched enough waves of “game-changing” technologies that never quite arrive to know that sometimes it’s the little tweaks that really count.

CES is more than just a neon-drenched show-and-tell session for the world’s biggest tech manufacturers. More and more, it’s also a place where companies showcase innovations that could truly make the world a better place — and at CES 2023, this type of tech was on full display. We saw everything from accessibility-minded PS5 controllers to pedal-powered smart desks. But of all the amazing innovations on display this year, these three impressed us the most:

Samsung's Relumino Mode
Across the globe, roughly 300 million people suffer from moderate to severe vision loss, and generally speaking, most TVs don’t take that into account. So in an effort to make television more accessible and enjoyable for those millions of people suffering from impaired vision, Samsung is adding a new picture mode to many of its new TVs.

Relumino Mode, as it’s called, works by adding a bunch of different visual filters to the picture simultaneously. Outlines of people and objects on screen are highlighted, the contrast and brightness of the overall picture are cranked up, and extra sharpness is applied to everything. The resulting video would likely look strange to people with normal vision, but for folks with low vision, it should look clearer and closer to "normal" than it otherwise would.
Excitingly, since Relumino Mode is ultimately just a clever software trick, this technology could theoretically be pushed out via a software update and installed on millions of existing Samsung TVs -- not just new and recently purchased ones.
