City buses are white and blue. Please board at the front door and pay the fare as you get on.
The fare per ride is $1.50 for adults and $1.00 for senior citizens. The fare may be paid by cash,
bus pass or multiple passes. Please pay the exact amount directly into the slot at the top of the far
e box. Remember that bills are not accepted and drivers cannot make change for riders.
When you wish to get off the bus, please notify the driver in advance by pressing one of the
buttons provided throughout the bus for this purpose. The bus may pass bus stops without
stopping if no one is getting off or waiting to get on.
There are five subway lines in the city. The fare is set at five rates from $2.00 to $3.50 according
to the number of predetermined "price zones" traveled. To purchase the appropriate ticket, please
check the fare on the boards installed above the ticket-selling machines in each subway station.
Pass through the automated ticket gates by inserting the ticket into the slot. When getting off the
subway at a station beyond the validity of the ticket, pay the additional fare at a fare-adjustment
machine.
