Knowra Congestion pricing Congestion pricing Congestion pricing charges vehicles for using roads or entering areas when traffic is heavy. It aims to reduce peak demand by making drivers account for the delays their trips impose on others.
Road pricing : Charging vehicles to use roads, usually according to where, when, or how far they travel. Congestion pricing is a time- or place-targeted form of road pricing.
Singapore Area Licensing Scheme : A 1975 Singapore program that charged vehicles to enter the central business district during peak periods. It was an early urban scheme that directly charged for entry to a congested area.
Induced demand : The increase in travel that follows an expansion of transport capacity or a reduction in its cost. Removing a charge can draw more drivers onto roads and weaken congestion relief over time.
Fuel tax : A tax levied on fuels, commonly based on the amount purchased. Fuel taxes apply broadly to driving and do not directly target a particular road or peak period.
Marginal-cost pricing : Setting a price equal to the additional cost caused by one more unit of consumption. The ideal congestion charge reflects the delay an additional vehicle imposes on others.
Singapore Electronic Road Pricing : Singapore's electronic system of road charges, with rates that can vary by location and time. It shows how technology supports time- and place-sensitive congestion charges.
Transport equity : The fair distribution of transport access, costs, benefits, and burdens across social groups. A flat charge can weigh more heavily on lower-income drivers unless alternatives or protections exist.
Vehicle registration tax : A government tax or fee associated with registering a motor vehicle. Registration charges usually depend on vehicle ownership, not the time and place of a trip.
Traffic flow : The movement of vehicles through roads, shaped by demand, capacity, speed, and interactions among drivers. Charges seek to keep vehicle demand below the level where traffic flow breaks down.
London congestion charge : A charge for driving within a designated central London zone during specified operating hours. London's scheme is a prominent area-entry charge designed to reduce central traffic.
