Bologna's closest airport is Guglielmo Marconi Bologna International Airport IATA: BLQ (http://www.bologna-airport.it/), just a few minutes from the city centre, served by taxi and a special bus line called the Aerobus (http://aerobus.bo.it/en). A taxi from the airport to the centre costs about €15. An Aerobus Ticket costs €6, and it stops outside the main terminal building. The ticket is also valid for 1 hour on the other buses in Bologna. Bus 54 goes towards the west suburbs of Bologna, and will get you on to the 'main' routes. Another bus stop is about 10 minutes walk from the airport bus stop name: Birra - other side of the elevated motorway, follow the road out of the airport, turn right at the first roundabout and straight through the second roundabout and you can board buses 81 and 91 which will take you to Bologna Central railway station. Bus tickets are valid for 60 minutes travel and cost €1.5. Go to the website of the local bus company, TPER, and you will find maps that show all routes including that of the airport bus.

Due to its central location and geography, Bologna has emerged as the main rail transport hub of northern Italy, making it very well connected with other major Italian cities. From 14 December 2008, the new high speed railway line is available to/from Milan, shortening the journey to 65 minutes. Bologna is also 37 minutes from Florence, 2 hours 20 minutes from Rome, 2 hours from Venice, 1 hour from Ferrara, etc. The new high speed train line between Rome and Bologna is now fully available and can make trips much faster.

Bologna is like any big city, parking is difficult but there are many car parks.Parking in the city centre (http://www.cookingclasses...) is available, many are open 24 hours.
The city is at the junction of the A1, A14 and A13 highways, and so is easily accessible from anywhere in Italy. Most traffic from Milan exits the A1 and take the Tangenziale, but beware this road at rush hour because it is horrendously packed. It may take around two hours from the A1 exit to the Tangenziale to the centre at certain peak times over summer busy weekends, especially at the beginning and end of August.
