An Automated Parking System is a mechanical device designed to minimize the space and/or amount required for storing vehicles. Compared to other parking systems that use manual controls or human supervision, an APS offers higher efficiency in parking. Unlike a conventional parking garage, an APS offers parking for vehicles on multiple floors where the cars are stacked to maximize available space while minimizing extra land-use costs. Moreover, an APS system can be used as a parking lot where vehicles are parked for extended periods. Such parking lot will be fully functional as long as the vehicles are not moved from the parking area until the day arrives when they need to be moved again. The APS may also be used to store cars that need repairs or regular maintenance and need parking for a long time. With these advantages, most people prefer to use automated parking units.
