There are many potential benefits from congestion pricing that depend upon the employed strategies and specific projects.
Decreased travel time from optimal traffic flow is associated with increased worker productivity, and decreased stress levels for drivers.
Improved air quality and reduced greenhouse gas emissions result from smoother flowing traffic.
Reduced expansion of the existing highway network thanks to efficient use of existing roadways minimizes impacts on neighborhoods, the environment, and local budgets.
Increased revenues from fees from congestion pricing are often re-invested to continually improve the road network and increase public transit availability.
Increased attractiveness of alternative transportation options may encourage motorists to use alternative travel modes, further benefiting air quality and mobility by removing vehicles from the road.
