| Puzzle Parking System | Motorized platforms move vertically and horizontally to position vehicles in a free parking space. | Approximately 6–50 vehicles per installation, depending on the number of levels and bays. | About 2–5 minutes for a standard retrieval cycle. | Usually saves approximately 30–60% of the parking footprint compared with conventional surface parking. | Residential buildings, commercial properties, hotels and small urban sites. | Modular design, relatively simple civil works and good use of irregular or narrow plots. | Some parking spaces may be temporarily unavailable while platforms are repositioned; vehicle dimensions and weight are restricted. |
| Tower Parking System | A central lift moves vehicles vertically while transfer mechanisms place them into parking bays arranged around the lift shaft. | Approximately 20–70 vehicles in a single tower, with higher capacities available in multi-tower projects. | About 2–4 minutes under normal operating conditions. | Can reduce the required ground footprint by approximately 60–80% compared with conventional parking layouts. | Dense urban developments, mixed-use towers and sites with limited land area. | High vertical capacity, compact land use and controlled pedestrian access. | Requires sufficient structural height, careful integration with building codes and access for maintenance. |
| Shuttle-Based Parking System | Automated shuttles transport vehicles along aisles, while lifts move them between floors and transfer units position them in storage bays. | Approximately 50–500 vehicles per facility, depending on the number of levels, aisles and shuttles. | About 2–5 minutes, with multiple shuttles able to operate simultaneously. | Typically provides approximately 40–70% greater parking density than conventional parking. | Large residential, office, airport, hospital and public parking facilities. | Scalable capacity, high throughput and potential redundancy when multiple shuttles are installed. | Higher capital cost, more complex controls and a greater need for coordinated maintenance. |
| Pallet-Based Parking System | Vehicles are parked on pallets that are moved by lifts, conveyors, transfer carts or rotating mechanisms. | Approximately 20–300 vehicles, depending on the layout and number of handling devices. | About 2–5 minutes for a typical retrieval, subject to vehicle position and system traffic. | Commonly achieves approximately 30–60% higher space utilization than conventional parking. | Basements, underground garages, commercial buildings and retrofit projects. | Accurate vehicle positioning, flexible layouts and reduced door-opening or pedestrian movement inside the garage. | Pallet handling adds equipment weight, operating steps and ongoing inspection requirements. |
| AGV or Robotic Parking System | Autonomous guided vehicles or robotic transporters collect vehicles and deliver them to designated storage positions without fixed parking aisles. | Approximately 100–1,000 vehicles in large-scale facilities, depending on the number of robots and storage levels. | About 2–5 minutes in optimized systems; peak-hour time depends on fleet size and traffic management. | Can provide approximately 50–70% higher density than conventional parking by reducing ramps and drive aisles. | Large underground garages, transport hubs, airports and high-density urban developments. | Flexible storage layout, high automation and reduced need for internal driving lanes. | Requires sophisticated software, precise vehicle positioning, charging or battery management and strong system integration. |
| Rotary Parking System | Vehicle platforms circulate vertically or horizontally on a continuous loop to bring the selected vehicle to the access level. | Usually 6–20 vehicles per module, with multiple modules used for larger capacity. | About 1–3 minutes for a single retrieval cycle. | Often reduces the ground area required per vehicle by approximately 40–70%. | Small commercial sites, residential properties and constrained urban plots. | Compact installation, comparatively fast operation and suitability for limited spaces. | Capacity is limited per module, vehicle loading order can affect retrieval time and maximum vehicle dimensions must be observed. |
| Semi-Automated Lift-and-Slide System | Hydraulic or electromechanical platforms lift vehicles vertically and slide them horizontally into available positions. | Approximately 2–30 vehicles, depending on the number of levels and platform arrangement. | About 1–4 minutes for a standard retrieval. | Typically improves parking capacity by approximately 40–100% compared with the same uncovered area. | Apartment buildings, small offices, dealerships and parking retrofits. | Lower complexity than fully robotic systems, flexible installation and relatively small construction requirements. | Drivers may need to follow loading procedures, and some configurations can require moving another vehicle before retrieval. |
