From Huffpo, commenting on a new report from the American Public Transportation Association:

Use of public transit simply means that you walk more which increases fitness levels and leads to healthier citizens. More importantly, increasing use of public transit may be the most effective traffic safety counter measure a community can employ,” noted APTA president William Millar. Apparently communities with vast public transportation networks don’t just live longer because of the exercise — they’re also less likely to be the victim of a fatal auto accident. The traffic fatality rate in the Bronx, New York is four in 100,000 contrasted by the traffic fatality rate in auto ridden Miami, Kansas which is 40 in 100,000.

Using public transportation also saves you a lot of money: “Riding public transportation saves individuals, on average, $9,381 annually and $782 per month based on the August 10, 2010 average national gas price ($2.78 per gallon- reported by AAA) and the national unreserved monthly parking rate.”

It is also important to note that when you pay $35 to fill your tank with gasoline, you haven’t actually paid for most of the costs of using gasoline.
