The New York Police Department said on Monday that it was cracking down on motorists this week in areas frequented by older adults, an announcement that came out the same day a 62-year-old woman was fatally struck by a city bus in Brooklyn.

The initiative follows a string of fatal collisions involving pedestrians and motorists in the past two months.

Police officers will target drivers who commit moving violations like speeding and failing to yield to pedestrians near senior centers during times when there are large numbers of people in those areas, officials said in an advisory distributed to members of the news media. The effort, called the Holiday Pedestrian Safety Initiative, began Monday and is expected to run until Sunday, according to the advisory.

The enforcement initiative focuses on seven moving violations outlined under Vision Zero, the mayor’s plan to eliminate pedestrian fatalities in the city. Other offenses include improper turns, texting or using a phone while driving, and traffic signal violations.
