The city of Seoul is sharing its public transport policies with officials from other countries this week at an online forum hosted by the World Bank.
It's called 'Transforming Transportation 2021,' and officials will be discussing ways to make cities more sustainable.
Seoul will be sharing what it's done to make the city safe and how it's planning to make the traffic system more efficient.
One thing it's done already is to offer inexpensive bicycle rentals that you can pick up and return just about anywhere in the city, and it's also put rules in place to enable the widespread use of electric scooters.
The forum runs for three days through Friday.
