Polly Trottenberg

Appointed in 2014 by Mayor Bill de Blasio, Commissioner Polly Trottenberg leads one of the nation’s largest and most diverse municipal transportation agencies, with 5,000 employees and a $14.5 billion 10-year capital plan. 

Responsible for overseeing New York City’s roads, bridges, traffic and lighting operations, parking, passenger ferry service and bicycle and pedestrian infrastructure, Commissioner Trottenberg has maintained the agency’s strong focus on safety, equity, sustainability and economic growth. She has helped lead New York City’s Vision Zero traffic safety initiative to reduce roadway fatalities and injuries, with a focus on redesigning hundreds of city streets. Among other critical efforts, Trottenberg has prioritized the expansion of street resurfacing and reconstruction, bridge rehabilitation and construction, improvement of bus system performance on city streets, building a cycling network of over 1,000 miles and doubling the country's largest bike share program.

Commissioner Trottenberg serves among the City's representatives on the Board of the Metropolitan Transportation Authority, the nation's largest transit agency. In 2015, she was named Chair of TRANSCOM, a coalition of 16 transportation and public safety agencies in the greater New York Metropolitan area that coordinate regional transportation management, data analysis and technology.

Trottenberg has over 24 years of experience in the public sector, including most recently at USDOT, where she served as the Under Secretary of Transportation for Policy and developed key initiatives for the Obama Administration, including the groundbreaking TIGER discretionary grant program. Previously, Trottenberg was the first Executive Director of Building America's Future, a non-profit organization that advocates for increased investment in infrastructure and major transportation policy reform. On Capitol Hill for 12 years, Trottenberg worked for U.S. Senators Charles Schumer, Daniel Patrick Moynihan and Barbara Boxer, and began her transportation career at the Port Authority of New York and New Jersey.

She graduated from Barnard College and received her Master's in Public Policy from the Kennedy School of Government.
