Uber plans to offer its pool car service at reduced fares on early-morning weekend hours to help people “transition” out of extended-hours MBTA weekend service, which is set to end March 19.

Chris Taylor, general manager of Uber in Boston, announced the temporary discounted service at a meeting of the MBTA Fiscal and Management Control Board on Monday afternoon. The control board recently voted to end the late-night T service.

“We want to make that transition a little bit easier,” Taylor said.

Taylor said Uber’s pool service, where different riders share the same car, would be available for a flat rate of $5 along subway and trolley lines. The discount will be available from 12:30 a.m. to 2 a.m. from March 19 through April 9.

Lawmakers on Friday unveiled a bill to regulate Uber and other ride-hailing services. Amendments to that bill are due by 10 a.m. Wednesday for a floor debate later that afternoon.
