After housing, public transportation is one of the largest monthly expenses for people living in large cities.
It's cheaper than owning a car and better for the environment, but taking the subway, trolley, or bus every day can be expensive.

1. London, England, $174
2. Dublin, Ireland, $131
3. Auckland, New Zealand, $122
4. New York City, $117
5. Tokyo, Japan, $110
Chicago ranks 11th, at $102 a month for public transportation.
