The Kyiv public transport system, except for taxi, uses a simple flat rate tariff system regardless of distance traveled: tickets or tokens must be purchased each time a vehicle is boarded. Digital ticket system is already established in Kyiv Metro, with plans for other transport modes. Discount passes are available for grade school and higher education students. Pensioners use public transportation free. There are monthly passes in all combinations of public transportation. Ticket prices are regulated by the city government, and the cost of one ride is far lower than in Western Europe.
