Semi-automated parking uses mechanical lifts, platforms or pallets to store vehicles more densely, while the driver still drives onto the platform and leaves the car. Unlike a fully automated parking system, the machine moves the platform, not the car through a building.
Common types are stackers, which lift one car above another, and puzzle systems, which shift platforms sideways and vertically to bring the requested car to the entry level. They are widely used in dense cities, residential buildings and sites where a ramped garage will not fit.
Advantages
- More cars in the same footprint, often roughly doubling capacity in a given area.
- Lower cost and complexity than fully automated systems.
- Fits under buildings and in tight sites without long ramps.
Trade-offs
- Retrieval time. Users may wait for platforms to move. See retrieval time.
- Vehicle limits. Height, length and weight limits can exclude larger vehicles.
- Maintenance. Mechanical systems need service contracts and backup plans for outages.
- Charging. EV charging on moving platforms needs special equipment.
- Code review. The AHJ may treat systems differently for fire protection and exiting. See AHJ.
The Parkonomics view
Semi-automated parking is the practical middle ground: more density than a ramp, less risk than a robot. It works best where users park daily and learn the routine.
