Mayor Zohran Kwame Mamdani and Department of Citywide Administrative Services (DCAS) Commissioner Yume Kitasei today announced that New York City will install intelligent speed assistance technology in 2,000 additional municipal vehicles over the next three years, tripling the City's commitment from 1,000 to 3,000 vehicles.
Intelligent speed assistance (ISA) limits vehicle acceleration when a vehicle exceeds the local speed limit or a speed threshold set by DCAS. The expansion advances Mayor Mamdani's commitment to lead by example by making New York City's municipal fleet the safest in the nation, as outlined in Vision Zero Reimagined, his 10-year street safety blueprint.
The expansion also builds on Executive Order 19, which directs DCAS to retrofit all nonemergency municipal trucks with pedestrian alerts and require pedestrian alerts and ISA in all new nonemergency vehicle and truck purchases.
DCAS announced the expansion at the City's 11th Annual Vision Zero Fleet Safety Forum. The agency also announced a partnership with New York City School Bus Umbrella Services (NYCSBUS) to install pedestrian alerts on 100 school buses, marking the first test of the technology for school transportation.
"Our administration holds all New Yorkers to the highest standards of street safety - and that starts with our City workers," said Mayor Mamdani. "We are tripling our investment in technology that helps prevent speeding and makes our streets safer for all New Yorkers, whether they're behind the wheel, crossing the street or riding a bike."
"What started as a pilot of just 50 vehicles has grown into a program that will soon reach 3,000 and has been a model for fleet safety across the nation," said DCAS Commissioner Yume Kitasei. "From speed assistance to pedestrian alerts, sideguards and all of the safety upgrades we continue to install and explore, we're investing in technology that builds a City fleet that is not only safer, but also more efficient and sustainable."
DCAS launched its ISA initiative in 2022 with 50 vehicles and has steadily expanded the program. More than 1,000 city vehicles are now equipped with the technology, and participating vehicles have logged more than 10 million miles.
A recent report by DCAS and the U.S. Department of Transportation's Volpe National Transportation Systems Center found that ISA reduced speeding among equipped vehicles by 64%. On high-speed roads, including highways, speeding dropped by 82%. The City's 2025 Safe Fleet Transition Plan (SFTP) identifies ISA as a best-practice safety technology and classifies it as "required technology," the plan's highest designation.
Through its Fleet Office of Real Time Tracking (FORT), DCAS monitors the movements including speed of more than 30,000 municipal vehicles and school buses. The office also manages the ISA initiative including speed-limit maps, tracking systems and controls that support the technology.
DCAS manages New York State's largest electric vehicle fleet and charging network, with more than 6,000 electric vehicles and 2,600 charging ports supporting City operations. The agency continues to expand the use of innovative technologies to make its fleet safer and more sustainable.
"In July 2026 Mayor Mamdani signed Executive Order 19 to improve fleet safety," said DCAS Deputy Commissioner and Chief Fleet Officer Keith Kerman. "At today's 11th Annual NYC Fleet Safety Forum at Queens Theatre, we are launching important initiatives to build on the executive order, tripling City vehicles with intelligent speed assistance (ISA) and introducing pedestrian alerts for the first time on school buses. Both technologies will help keep New Yorkers safe."
"We have worked with DCAS to implement the Safe Fleet Transition Plan for school buses including telematics, training and introducing intelligent speed assistance," said Matt Berlin, CEO of NYCSBUS. "We are excited to move to the next stage of this implementation by testing pedestrian turn alerts in various configurations so that we can continue to keep school busing one of the safest modes of transportation in the city."
"By tripling the number of municipal vehicles equipped with this proven, cutting-edge ISA technology, DCAS will reduce speeding and significantly improve safety on our streets. I am eager to see this model swiftly imposed on the personal vehicles of dangerous drivers across the city," said Council Member Lincoln Restler.
"My son Sammy was killed by a speeding driver just steps from our home," said Amy Cohen, founder and president of Families for Safe Streets. "Intelligent Speed Assistance is exactly the kind of proven, common-sense technology that prevents tragedies like ours. We applaud Mayor Mamdani and DCAS for tripling this commitment, and we urge every city fleet in the country to follow New York's lead."
"Safe vehicles save lives, and that starts with our city fleet," said Ben Furnas, Executive Director of Transportation Alternatives. "New York City's fleet has been a longtime leader on intelligent speed assistance, and we're incredibly excited that the highly successful program will triple in size. With these safety updates, we can ensure that city vehicles save lives, not take them and lead the way on vehicle safety. This is proof that this technology is ready for the city's most dangerous drivers, and we'll keep fighting to ensure Stop Super Speeders passes the city council and is implemented imminently."
