Yet another benefit from  congestion pricing.  ​While congestion pricing is routinely touted for its role in tempering traffic demand, smoothing travel times, and cleaning urban air, a new study from the National Bureau of Economic Research reveals a a related public safety dividend: faster emergency response.
​Analyzing New York City’s landmark cordon-based pricing program—implemented in January 2025—researchers Yulia Chikish, Gregory J. Colman, and their colleagues utilized a robust “difference-in-discontinuities” design to estimate the program’s impact from distinct from other operational variables. By examining approximately 1.6 million emergency medical service (EMS) incidents near the program’s 60th Street boundary, the authors demonstrate that the pricing scheme is not merely a traffic management tool, but a public health intervention.
Pricing led to a roughly 21 percent reduction in passenger vehicle traffic near the pricing boundary, which in turn yielded tangible improvements in emergency response times. As the authors conclude:
​”These findings suggest that cost-benefit analyses of congestion pricing systematically understate net social benefits by omitting emergency response improvements.”
​For urban planners and policymakers—especially those currently navigating the complexities of large-scale infrastructure and tolling projects—this evidence offers a powerful rejoinder to skeptics. When we clear the clutter of congestion, we aren’t just saving time for commuters; we are explicitly improving the efficacy of the critical systems that keep our cities resilient. The “social benefit” of congestion pricing is far larger, and more urgent, than our traditional metrics have acknowledged.  Maybe cities around the country can enlist ambulance companies and fire departments in helping to make the case for congestion pricing.
