The American Public Transit Association released a statement saying "According to the 2009 Urban Mobility Report, public transportation saved 646 million hours in travel time and 398 million gallons of fuel. Without public transportation, the report states that congestion costs would have risen 16 percent to an additional $13.7 billion since 2005."
Well, since total transit spending is $44.3 billion per year, this means we are spending $3.23 for every $1.00 purportedly saved from congestion costs by transit. What a deal!! A few more "values" like that and we will be flat broke.
