Vertical design of parking lots refers to the arrangement and organization of parking spaces in a multi-level structure. It involves efficient use of space by stacking parking spaces vertically, often through the use of elevators, escalators, and ramps. This design is particularly useful in urban areas where land is scarce. It includes considerations such as the size and spacing of parking spaces, circulation systems, and safety measures. Some common types of vertical parking structures include garages, parking decks, and multi-level parking facilities.
