In the first month of congestion pricing, the MTA reported over 1 million fewer vehicle entries into the toll zone than would be expected without the program, driving the significant traffic reduction seen above. It’s also worth noting that the above chart shows reduction in travel times rather than congestion—in many cases, congestion has completely disappeared, and the new travel times represent a congestion-free trip. This reduction reverses a years-long trend of rising traffic into Manhattan - congestion pricing took a worsening gridlock problem and solved a significant portion of it overnight. Additionally, while there were fears that congestion pricing would just re-route traffic to other boroughs, the data from the first months of congestion pricing suggests that traffic has not increased elsewhere in the city.
Transit ridership has seen a notable spike since the implementation of congestion pricing as travelers into Manhattan are switching from driving to transit.
The MTA as a whole is averaging 448K more public transit riders per day this year. To put this into perspective, the second-highest ridership subway in the US is the DC Metro, which averaged 304K riders per day in January this year. The MTA ridership growth since congestion pricing went into effect is almost 50% larger than the total ridership of America’s next-largest subway system.
Unsurprisingly, bus ridership has seen the greatest relative growth, likely due to the fact that it most immediately benefits from congestion pricing thanks to faster travel times.
congestion pricing has been pretty consistently found to make air quality better for obvious reasons (fewer cars on the roads) so you can safely infer this is also the case here. unfortunately, there are several significant air quality variables outside of NYC's control that are probably going to make reductions less obvious than, say, Stockholm or London. most recently, nearby and unseasonable wildfires caused the city to have several days of terrible air quality. back in 2023, those huge Canadian wildfires caused the same problems on and off for their entire duragion.
