The 16 most expensive cities in the world for commuting to work

Next to housing, transportation is one of the largest recurring expenses people face. In a major metropolis, that likely means a fair amount of time packed into the subway, trolley, or bus getting a little too acquainted with your fellow city dwellers.

The good news: It's better for the environment, and, depending on where you live, it may be cheaper than owning a car.

The bad news: It can still be really expensive.

In London, the most expensive city in the world for public transportation, you'll need to shell out nearly $175 for a month of riding the Tube. In New York City, a monthly transit pass costs about $120.

That's according to a recent report by Deutsche Bank, which analyzes the cost of living and compares prices among the largest cities around the world.

The report sources prices from Expatistan, a site that tracks cost-of-living expenses in over 200 countries, for a "monthly ticket public transport" in nearly 50 cities.
