But six pedestrian deaths in a three-day period last week served as a reminder of the dangers that still plague New York City’s streets. The fatalities have prompted city officials to increase police enforcement efforts targeting commercial trucks, which were involved in four of the six deaths.

The fatal collisions began Wednesday morning when a 67-year-old man was struck in Flushing, Queens, and a 75-year-old woman was hit in Sunset Park, Brooklyn.

The next day near Sunset Park, an 85-year-old man was struck by a box truck as he crossed the street. Later that day, a 26-year-old woman was killed after a truck backed into her in the SoHo neighborhood of Manhattan.

On Friday morning, another truck hit a man in Hell’s Kitchen, and three vehicles struck a 57-year-old man in Gowanus, Brooklyn.
