The new head of the Metropolitan Transit Authority in New York City is Jay H. Walder, the creator of a congestion pricing system in London, and observers have noted the renewed possibility of congestion pricing for drivers of new and used cars in New York.

It’s a system that advocates say relieves rush hour traffic by charging drivers different rates at toll points based on the number of vehicles in an area, and a commentary on Cars.com casts doubt on some of the benefits. While it has been proven to improve traffic flow by limiting the numbers of cars at peak hours, there may be less of an environmental impact because of the decreased usage of mass transit options.

A Wall Street Journal editorial noted that a traffic program that made sense in city like New York would include tolls on all bridges and impose costs for parking curbside throughout the metropolitan area. As the Cars.com piece noted, doing so could increase the number of people who use mass transit to commute into New York City.

While previous debates have had little effect on the problem, owners of used cars in New York may want to factor potential tolls and parking costs into the budget for their next vehicle.
