A new U of PA study, 'Guaranteed Parking, Guaranteed Driving' compares two NYC neighborhoods, showing decisively that providing off-street parking is a sure way to guarantee more driving.

"The study (by University of Pennsylvania planning professor Rachel Weinberger), "Guaranteed Parking, Guaranteed Driving", compares parking and commuting habits in Park Slope, Brooklyn and Jackson Heights, Queens. The study finds that despite having the same car ownership and very similar access to public transit to the Central Business District, Jackson Heights residents are 45% more likely to drive to work in the Central Business District and 28% more likely to drive to work in general.

The study concludes that Jackson Heights car owners are more likely to drive to work because of guaranteed, off-street parking spots to return to at the end of the day."

From Steetsblog: Study - City Residential Parking Requirements Lead to More Driving: "In August, Weinberger teamed with Transportation Alternatives and other groups concerned about parking reform to issue "Suburbanizing the City". [See related link] That study estimated that the city's parking requirement would generate a billion miles of new traffic a year by 2030. "Guaranteed Parking" substantiates that finding, and provides more evidence that New York City zoning regulations promote driving to work, even when viable transit options are available."
