A group supporting congestion pricing released data Tuesday, targeting metro area state lawmakers.

The Tri-State Transportation Campaign said few commuters depend on cars and those that do generally make more than those who use public transportation.

The study examines census data from the 140 State Assembly and State Senate Districts in the MTA region and found that, in 90 percent of the districts, less than five percent of the commuters would have to pay the congestion pricing charges. In other districts, meanwhile, the number of commuters affected would be less than ten percent.

In most State Senate and State Assembly districts, public transportation users outnumber drivers by as much as 30 to 1, said Tri-State Transportation Campaign Executive Director Nick Sifuentes.

The highest percentage of commuters who would be tolled actually live in Manhattan, and many of them use taxis many of them use taxis to get to work, according to the study. Staten Island takes second place. The lowest percentage of commuters who would be tolled live in Brooklyn and the Bronx, the campaign said.

"People who are driving into the central business district of Manhattan are pretty uniformly a lot wealthier than people taking public transit, so the folks who would have to potentially change behavior or who would pay a toll are the kind of folks who are already making quite a bit of money anyway, so it's equitable to make sure there's a toll in place," said Sifuentes.

The study does have a shortcoming: It looks only at commuters; it does not examine truck traffic, people making occasional trips, or people taking for-hire vehicles outside of commuting.

The study was released two weeks after Gov. Andrew Cuomo's panel announced its congestion pricing plan. The state legislature has until June to pass it, if it votes to do so, until it adjourns for the year.
