A pilot project that uses technology to sync up MTA buses with traffic lights — turning signals green faster as the buses approach — is about to expand, much to the chagrin of other drivers.

The program has been operating along five bus routes since 2006, and the vehicles’ times have improved so much that the city is now planning to install the technology at 1,000 intersections citywide by 2020, officials said Monday.

But drivers’ advocates say the move will just make traffic even more congested than it already is.

“We know mass transit in this city is a disaster and something needs to be done, but if you do it at the expense of other vehicles, you’re serving nobody,’’ said New York Taxi Workers Alliance Executive Director Bhairavi Desai.

Uber driver Oscar Martinez agreed.

“When the light changes so quickly, everybody gets stuck,’’ he said.

The lights timed to buses are currently located along Hylan Boulevard in Staten Island, First and Second avenues in Manhattan, Nostrand and Utica avenues in Brooklyn, and Webster Avenue in The Bronx.
