A New York City taxi driver’s group will stage an October 22 strike — its second in two months — over new requirements for GPS and credit card equipment.

The 24-hour walkout by the Taxi Workers Alliance will begin at 5 a.m. on that Monday, and include a lunchtime demonstration outside the Taxi & Limousine Commission in Lower Manhattan, its executive director, Bhairavi Desai, said.

Ms. Desai predicted thousands of drivers would participate. The group says it represents about one-fifth of the city’s 44,000 licensed taxi drivers.

“We’re asking all the drivers to leave all taxis parked but to come to the demonstration,” she said. “There will be picket lines, starting in the early morning, at different garages and at transportation hubs,” including Penn Station and Grand Central Terminal.

Mayor Bloomberg has said that the city would be ready, but told the taxi drivers it was in their best financial interest to keep working.

Susan Leone of Brooklyn was one of several people in Manhattan today who said they would not be deterred by a strike.

“If I have a meeting I take a taxi, otherwise I take a subway,” she said. “I would just figure out another route.”
