Inspired by His Grandparents, High Schooler Invents Crosswalk System That Adapts to Pedestrians’ Speeds
A high school student in South Korea developed an adaptive crosswalk system that adjusts traffic signals based on pedestrians' walking speeds, inspired by the challenges his grandparents faced crossing streets. The invention, called SmartBlink, uses real-time data to extend crossing time for slower individuals, such as the elderly and those with mobility disabilities, and won top honors at a major science fair. The system aims to improve safety and accessibility for all pedestrians by accounting for varying movement speeds. The student is now working to promote the technology for broader implementation.
A high school student created an adaptive crosswalk system that adjusts traffic light timing based on how fast pedestrians are moving.
The system helps older adults and people with mobility challenges cross streets safely by accounting for their slower walking speeds.
The story highlights how young innovators can use technology to make public spaces more inclusive and accessible for everyone.
