As South Korea ages more quickly than most other countries on the planet, it’s doing something new to help those in the twilight of their lives: slowing down changes in traffic signals to allow more time to cross the road.

The Seoul city government said on Monday it will lengthen intervals between changes in traffic signals by the end of this year in 59 areas where welfare centers are located for the aged.

Traffic signals in those areas will be adjusted for a walking speed of 0.8 meter per second, slower than the current speed of one meter per second. The new standard will allow people an additional 7.5 seconds to complete a 30-meter crosswalk.

The city government said it also plans to make traffic lights transition more slowly from red to green in the same areas because the elderly react slowly to signal changes.
