$345 -- The amount saved yearly by cycling to work, assuming a five-day work week, a 16-mile roundtrip commute, gas at $1.80 per gallon, and a car that gets 25 miles to the gallon.

58 hours -- The time the average Boston commuter is stuck in gridlock each year.

15 percent -- The portion of an average Boston household's budget spent on transportation.
