The Taxi and Limousine Commission is getting to release 6,000 new green taxi cab permits beginning in August. A year after the first green taxis hit the streets in Northern Manhattan; the program has been a success, opening new transportation options for residents and new business opportunities for cabbies. 7 million New Yorkers have taken rides in the green cabs since the first permit was sold last June. The green cabs, was introduced in 2012 as a way to provide metered fare service to outer-borough riders who are often not served by yellow cabbies. The street hail livery program has gone so far in filling a transportation gap in areas undserved by mass transit, like areas in Brooklyn, Queens and some northern areas in Manhattan. The program received criticism for picking up passengers in lower Manhattan, said the Taxi and Limousine Commissioner Meera Joshi to the City Council today. Green taxis are only allowed to pick up fares in the outer boroughs and above 96th street on the east side, 110th street on the west side. The meters in green cabs automatically shut off outside their designated zone and their lights dim.
