The New York City Council plans to introduce legislation on regulating the app-driven service Uber and other for-hire vehicles in coming weeks, moving ahead of Mayor Bill de Blasio and his delayed study on the industry.

The City Council is in the final stages of drafting the legislation, according to a council official.

Council members were briefed on the legislation Thursday afternoon.

Mr. de Blasio commissioned a four-month, $2 million study earlier this year after his proposal to cap the number of for-hire vehicles in New York City failed in the City Council because Speaker Melissa Mark-Viverito refused to schedule a vote. The study had been expected in November but hasn’t been released.

Ms. Mark-Viverito supports the council’s proposed legislation and has been involved in the discussions about it. The bill could be introduced at the next council meeting, on Jan. 20, according to a council official briefed on the matter.
