This enlightening intel comes from the folks at Expert Market, who crunched the numbers on a whole slew of relevant data to figure out just how rough the daily slog to and from the office compares in 74 "hotspots" with 300,000 or more residents in 16 countries. Specifically, they looked at seven different metrics for each including the average time spent commuting each day, average daily wait time for a bus/train, average journey distance (one way), and the percentage of commuters who must make at least one change as part of their trek (e.g., transfer). They also looked at the average cost of a monthly travel card as a percentage of the average monthly salary in a given place, and the average number of hours spent in congestion while commuting per year. In other words, they were very thorough.
Topping the list of cities with the worst commutes is Rio de Janeiro, followed by Bogota, and then Sao Paulo. As for where you can expect the "best" commute, Nice, France is number one, followed by Cuenca, Ecuador and then Bilbao, Spain. The full ranking's right here, but this is how things shook out at the top and bottom of the list.
