Road Tolls: Tolls are a common way to fund highway and bridge improvements. Such tolls are a fee-for-service, with revenues dedicated to roadway project costs.
Congestion Pricing: (also called Value Pricing) refers to variable road tolls (higher prices under congested conditions and lower prices at less congested times and locations) intended to reduce peak-period traffic volumes to optimal levels.
Cordon (Area) Tolls: are fees paid by motorists to drive in a particular area, usually a city center. Some cordon tolls only apply during peak periods, such as weekdays.
HOT Lanes: High Occupancy Toll (HOT) lanes are High Occupancy Vehicle (
HOV) lanes that also allow use by a limited number of low occupancy vehicles if they pay a toll.
Vehicle Use Fees: Distance-Based Charges such as mileage fees can be used to fund roadways or reduce traffic impacts, including congestion, pollution and accident risk.
Road Space Rationing: A variation of road pricing is to ration peak period vehicle-trips or vehicle-miles using a revenue-neutral credit-based system. Look for
