A vast majority of New Yorkers want more cops in the subways and do not feel safe riding the trains at night, a Quinnipiac University poll published Wednesday found.

The poll from April 28 through May 2 of 1,249 registered voters in the city found 86% of respondents wanted more police officers in the mass transit system, where major felonies are up 63% so far this year from the same period of 2021.

Roughly 61% said they feel unsafe riding at night, compared with 43% of respondents who fear the trains during the daytime.

“I do look over my shoulder more than I used to,” said Wendy Rosa, 48, who lives in Bushwick, Brooklyn, and commutes on the L line. “There’s days when there’s a lot of police in the subway, and there’s days when there are no police in the subway. I wish there was some type of balance.”

The fear of the subways comes as Mayor Adams and Metropolitan Transportation Authority officials have called for sharp crime crackdowns on mass transit.

Subway ridership is down 40% from before the pandemic, a decline MTA officials largely attribute due to the growth of remote work.

MTA Chairman Janno Lieber during an appearance Wednesday on WNYC’s “The Brian Lehrer Show” also cited the fear of crime as a reason riders are staying away.

“What people are feeling is a sense of disorder on the system,” said Lieber. “There’s smoking, there’s open drug use, there’s vandalism. When people see that they think, ‘What might that person do to me?’”

The poll numbers show New Yorkers are losing faith in Adams’ efforts to reduce crime, which was his central campaign promise last year as he ran for mayor.
