Parking is the act of stopping and disengaging a vehicle and leaving it unoccupied. Parking on one or both sides of a road is often permitted, though sometimes with restrictions. Some buildings have parking facilities for use of the buildings' users. Countries and local governments have rules for design and use of parking spaces.
Car parking is essential to car-based travel. Cars are typically stationary around 95 per cent of the time. The availability and price of car parking supports and subsidize car dependency. Car parking uses up a lot of urban land, especially in North America - as much as half in many North American city centers.
