Florence public transportation
The city of Florence has got an urban bus service managed by ATAF & Linea.
ATAF
ATAF buses are coloured in orange, and, starting from August 2010, also white&red.
ATAF tickes are sold at many shops and newsagent's shop, just look for an orange sticker Biglietti ATAF on the entrance doors.
You could also purchase them on board (as soon as you get on the bus), but it will cost you more, 2 euros, and the driver can refuse to sell or not give change. So it's better to buy them before getting on the bus. There is an exception: the ticket for Volainbus 55 shuttle line (from and to Florence airport) can be purchased on the bus without an extra fee. Please note that normal ATAF tickets are not valid for that bus line.
A single trip ticket costs 1.20 euros and is valid for 90 minutes from the time it's stamped.
Tickets must be stamped as soon as you get on the first bus, are time based and are valid 90 minutes from the time it's stamped. You can get all the ATAF buses you want in those 90 minutes (you don't have to stamp them each time), but when time is over, you have to stamp a new trip. A 2 trips (biglietto da due corse in Italian) ticket costs 2.40 euros, a 4 trips one costs 4.70 euros.
There are also 24 hours tickets, at the cost of 5 euro, and tickets lasting 3 days at 12 euro or 7 days at 18 euros.
The main ATAF information desk is outside Florence Railway Station Santa Maria Novella, you can ask them a timetable. See the official site for opening times.
Taxi
