The New York City DOT just released maps showing how speed limits have changed since de Blasio lowered the NYC default speed limit to 25 mph in an effort to reduce the number of fatal car accidents
Decreasing the speed to reduce the number of car accidents resulting in death or serious injury in New York City is one of the top priorities of the Zero Vision Initiative launched by Mayor de Blasio in 2014. Since November 7, 2014, the NYC’s default speed limit has been lowered from 30 mph to 25 mph and since that date the NYC Department of transportation has been implementing it. The DOT re-evaluated for each borough which streets should have their speed limit lowered to 25mph and which ones should be allowed to keep a 30 mph speed limit. The DOT posted over 4,700 new 25 mph signs and removed 2,400 30 mph signs. There are still 700 more to be removed. At this point over 5,000 miles of NYC streets have a 25 mph or lower speed limit and over 800 miles of the streets have signs that explicitly indicate that the speed limit is 25 mph. The DOT also added speed limits in the Vision Zero Map of traffic crashes. Read more in Streetblog
