Congestion pricing

Congestion pricing is a surcharge system applied to public goods experiencing overuse, like roads, public transport, and utilities, during peak demand. It aims to manage congestion by regulating demand, effectively reducing overcrowding without needing to expand the supply of the good or service. Examples include higher fees during rush hour for buses, electricity, trains, roads (road pricing), airport slots, and canal usage. This approach encourages users to shift their consumption to off-peak times or explore alternative options, ultimately improving efficiency and reducing overall congestion.
