The mayor and some City Council leaders were pushing Monday for speed cameras throughout the five boroughs, as the Department Of Transportation released a map of 100 locations where a study found at least 75 percent of tracked traffic speeds past nearby public schools.

While the exact methodology of the DOT study is not known, the department says the worst spots in each borough are P.S. 60 on Staten Island, P.S. 54 in Queens and P.S. 233 in Brooklyn, where 100 percent of vehicles sped past; P.S. 48 in Manhattan, where 97 percent of vehicles sped past; and P.S. 81 in the Bronx, where 96 percent of vehicles sped past.

Transportation officials say that speed is the single greatest contributing factor to traffic deaths, leading to 81 of the 274 fatalities in 2012.
