The Federal Highway Administration’s (FHWA) Office of Operations recently released the report Synthesis of Congestion Pricing-Related Environmental Impact, which summarizes the state of the practice and provides a framework for evaluating the environmental impacts of congestion pricing projects. Examples of congestion pricing include high-occupancy toll (HOT) lanes and cordon or area pricing schemes. The environmental impact focuses include air quality, noise, and environmental justice. The report also discusses the evaluation of travel impacts caused by congestion pricing, which include traffic, transit, and travel behavior.
