:: Urban Traffic
Bologna is just a medium-sized city, but particularly in the city center, traffic often causes various inconveniences and contributes to a troubling pollution problem.

Flash suggestion: if you live in the center, use a bicycle. Bikes don't pollute, and you can get anywhere on one.
Otherwise, the ATC public transportation system is very well organized. Buses are frequent during the day, and there are special lines for night-time service. All the information in English are in the pages of IAT:
