New York City's 75,900 parking meters produced $114 million in 2007, and city officials anticipate $120 million in meter revenue this year. The estimated increase is due in small part to a new pilot program that doubles parking-meter rates during heavy traffic periods. Park Smart NYC's goal is to increase turnover in curbside parking spaces so that drivers will spend less time cruising in search of an open space, decreasing pollution and traffic congestion. Meter rates will be $2 an hour from noon to 4 p.m. and $1 an hour at all other times that meters are in effect. The trial started in October in Greenwich Village, and will run six months. If it's successful, it will be expanded.
