New study provides evidence about New York City's speed camera program

This study evaluates the largest automated speed enforcement program in the United States—2,000 cameras deployed across New York City from 2014 to 2023. Leveraging data on 700,000 collisions and 18 million speeding tickets, the analysis finds that cameras lead to persistent and sustained reductions in crashes. These results demonstrate that automated enforcement can meaningfully improve road safety while avoiding the harms associated with conventional traffic safety approaches.
