NYPD traffic tickets and summonses for minor offenses have dropped off by a staggering 94 percent following the execution of two cops — as officers feel betrayed by the mayor and fear for their safety, The Post has learned.

The dramatic drop comes as Police Commissioner Bill Bratton and Mayor Bill de Blasio plan to hold an emergency summit on Tuesday with the heads of the five police unions to try to close the widening rift between cops and the administration.

The unprecedented meeting is being held at the new Police Academy in Queens at 2 p.m., sources said.

Angry union leaders have ordered drastic measures for their members since the Dec. 20 assassination of two NYPD cops in a patrol car, including that two units respond to every call.

It has helped contribute to a nose dive in low-level policing, with overall arrests down 66 percent for the week starting Dec. 22 compared with the same period in 2013, stats show.

Citations for traffic violations fell by 94 percent, from 10,069 to 587, during that time frame.

Summonses for low-level offenses like public drinking and urination also plunged 94 percent — from 4,831 to 300.
