Men and twentysomethings are pedestrians most likely to be killed by motorists in New York City, according to a new Health Department report analyzing traffic data.

Although traffic deaths reached an all-time low last year, pedestrians made up 52 percent of people killed on city streets. More than half of the fatalities happened on major streets. Intersections also were a dangerous area, accounting for 66 percent of pedestrian deaths.

A Transportation Alternatives statement Monday told drivers to slow down. More than 1 in 4 traffic deaths involved “unsafe speeds,” the report said.

Department of Transportation officials attribute the reduced numbers to shorter pedestrian crossings, longer traffic islands and wider sidewalks.
