CITY HALL -- Traffic fatalities decreased on Staten Island last year, but are still up since Mayor Bill de Blasio launched "Vision Zero" in 2014.

There were 17 borough traffic deaths last year, a 32 percent drop compared to 2015, according to the Department of Transportation.

That sizable percentage decrease last year reflects that traffic fatalities more than doubled the year before -- 25 people died on Staten Island streets in 2015.

Last year's smaller death tally is still more than the 11 deaths in 2014, the year de Blasio launched the citywide effort to completely eliminate traffic fatalities.

There were 229 traffic fatalities citywide in 2016, the safest year on record.

"No loss of life on our streets is acceptable," Mayor Bill de Blasio said in a statement. "Under Vision Zero, we have now seen traffic fatalities in our City decline for three straight years, strongly countering national trends."

Pedestrian deaths increased citywide last year, but decreased by four on Staten Island.

Seven pedestrians, one bicyclist, two motorcyclists and seven motor vehicle occupants died in the borough last year.

The city said that fewer people died along Hylan Boulevard, a "priority corridor." There were eight traffic fatalities along the busy road in 2015 and four last year.

The Department of Transportation added pedestrian head starts and other safety measures along Hylan. The 122nd and 123rd precincts and Highway 5 also increased speeding enforcement.
