Description: Transportation Demand Management or Cordon Area Congestion Pricing (also called Value Pricing by the Federal Highway Authority) is considered by most transportation experts to be the most effective strategy of reducing congestion, a potential proxy for vehicle miles traveled and emissions.
Congestion pricing is a way of harnessing the power of the market to reduce emissions associated with traffic congestion. Congestion pricing works by shifting some rush hour highway travel to other transportation modes or to off-peak periods.
Studies also indicate that congestion pricing will result in increased walking, biking, and use of transit.
Goal: Reduce vehicle miles traveled (VMT) by congestion pricing, particularly of solo-occupant motor vehicles and during peak hour times. Reduced VMTs will reduce GHG emissions by the city’s transportation sector and incentivize use of other modes of transportation.
Raise revenue to improve public transportation and promote walking and biking.
Measurement: Reduced VMT, increased mph, reduced congestion (level of service)
Time to Implement: Varies

London – Congestion Charge
Stockholm – Congestion Tax
In the U.S., New York has adopted congestion pricing for New York City; Seattle, Los Angeles, and Portland are considering forms of congestion pricing.
