Horizontal Circulation System (CLICK TO SEE MOVIE)

The most concentrated way of parking cars. Almost no wasted space. Usually used below ground with elevator access. It is possible to park one thousand cars in 120,000 square feet, 7 feet in height or 840,000 cubic feet. The platforms are circulated around the floor area horizontally by moving one line in one direction and an adjacent line in the opposite direction towards an empty space. The platforms on the ends are then transferred foreword and rearward, in opposite directions, to create a new empty space on the opposite ends of the two lines. Normally used for longer-term parking as recovery speeds can be slow for long systems. Mechanical design is fairly simple and installation costs should be moderate. Operational speeds are moderate but retrieval times can be increased with good design of input/output systems. These systems are made from structural steel which generally can be torn down and salvaged. Also the space can easily be reconfigured once the structural steel has been removed.
