MARTA pricing might be the easiest of any transport system. Atlanta’s Marta system uses the “Breeze” fare collection system which is basically a ticket or a card instead of tokens. Check out the Breeze site for more details. It’s easy to use and the card can be reloaded making it easier than carrying change.
The basic fare on MARTA is $2.00. There are some discounts available for monthly passes and group discounts.
