Mr. Cuomo’s plan: Put 500 uniformed officers on bus routes and in subway stations.

Here’s what you need to know:

What are the details?

Mr. Cuomo wants to address two problems: fare evasion and assaults on transit workers.

“There’s a high correlation” between the two, he said on Monday at a news conference in Manhattan. (A spokesman for the governor said on Tuesday that the Metropolitan Transportation Authority had determined that many perpetrators of other crimes on the subway had not paid their fare during that trip.)

The governor has announced three tactics:

Starting Monday, according to a spokesman for Mr. Cuomo, 500 uniformed officers will be sent to 50 subway stations and 50 bus routes where evasion and assaults occur at elevated rates. The governor said that announcing specific locations would undermine the effort.

Exit gates will be redesigned at stations where people can easily enter without paying. A timetable for the redesign was not announced.

Video cameras will be used to curb fare evasion. A timetable for this plan also was not announced.

Who are the officers?

Two hundred are New York Police Department officers, and 300 are M.T.A. police officers or bridge and tunnel officers. An additional 70 M.T.A. employees, in so-called “eagle teams ,” will also be part of the effort.

How will they deter fare evasion?

The plan relies on two enforcement tools: the officers’ presence, and the issuance of civil summonses. A summons is similar to a parking ticket.

“It’s not criminalizing fare evasion,” Patrick J. Foye, the M.T.A. chairman, said at the Monday news conference. “This is about deterrence, not arrests.”
