Congestion pricing is a vehicle tolling system that imposes fees to drive within a congested area, typically a downtown district. Cities that already have congestion pricing policies in place have been studied extensively. Notable examples are Singapore, London, Stockholm, Milan, and Gothenburg. These cities have appreciated a range of benefits from congestion pricing, including reductions in peak traffic, vehicle miles traveled, and emissions, as well as increased revenues for transportation investments.
