• New York City is poised to launch the first congestion pricing plan to reduce traffic in a major U.S. metropolitan area.
• Like many journeys in the Big Apple, this one has been punctuated by delays.
• Once the system starts up, however, it’s expected to significantly reduce gridlock in Manhattan and generate billions of dollars to improve public transit citywide.
• As an urban policy scholar, I’m looking forward to seeing New York’s plan go into effect.
• But given the heavy costs that traffic imposes on public health and productivity, I’m encouraged to see a major U.S. city finally test this approach.

Nudging drivers

• Congestion pricing is a response to externalities – costs or benefits that are generated by one party but incurred by another.
• Clogged city streets and air pollution are externalities created by urban car users, many of whom live outside the city.
• This approach is behind behavioral economics, the policy strategy of using “nudges” that preserve choice but encourage certain actions.

Public transit receives priority

• The New York plan was presented to the board of the Metropolitan Transit Authority in November 2023 after years of study and a detailed environmental impact assessment, required by federal law.
• It also would generate US$15 billion for capital improvements to the city’s public transit system, including making stations accessible for passengers with disabilities and buying new electric buses and commuter rail and subway cars.
• More than 75% of all trips into the central business district are made by public transit.

• Over several months of public hearings, the MTA heard both broad support for congestion pricing and thousands of requests for credits, discounts and exemptions, most of which were denied.
• The limited number of exemptions includes private commuter buses, school buses and city-owned vehicles, including emergency vehicles.
• New Jersey is suing the MTA, arguing among other things that the plan is unconstitutional because it burdens interstate commerce.

Starting the journey

• And how will commuters respond when they find that trains and subways initially are more crowded, before capital upgrades improve the system?
• But freedom for car users has imposed health and economic costs on millions of New Yorkers for many years.
• But if New York’s experiment succeeds, it could provide a model and valuable insights for other traffic-clogged U.S. cities.
