South Korea is introducing a system of separate pedestrian lanes for fast and slow walking. This innovation is aimed at reducing the stress of walking in heavy pedestrian traffic and improving comfort for all road users, reports ruspioner.ru.

The sidewalks are divided into two zones. The blue stripe is designed for the usual urban walking pace, while the green stripe is for "slow traffic": elderly people, tourists with luggage, families with children, and anyone else in a leisurely pace.
