The availability and cost of parking is an important determinant of whether or not people choose to drive to a particular destination, and also whether they choose to own a car at all. Local authorities have direct control over the use of kerb-space in their areas, and therefore of the supply and price of on-street parking. Many authorities own public off-street car parks, over whose use and price they also have control. They also have some control over the level of parking that is provided in new developments.
Traffic and demand management refers to measures such as parking management, reallocating urban space in favour of sustainable modes of transport (including shared space), access controls, road pricing, and traffic signal control strategies.
