A 52-year-old man was in critical condition yesterday after he was hit by car in Bedford-Stuyvesant, police said. The accident occured just as cops began a city week-long traffic crackdown.

The man, whose name was not released, was crossing Atlantic Avenue near Bedford Avenue just before 12:30 a.m., police said.

He was allegedly run over by a black 2013 Dodge Charger heading west on Atlantic Avenue. He's in critical condition at Kings County Hospital Center.

Robert Daniel, 35, was charged with driving while intoxicated and vehicular assault.
