This is probably the most efficient carpark layout. The spiral car park needs
to be about 16m wide and needs to be a minimum of 57m long to work well. Users
spiral up and down on the same ramps.
Split Level Car Park
The split level car park is a highly efficient shape, especially suited to a
site with a slope of 1.5m over the 32m width. The longer the better for
efficiency, it will normally be 32m wide.
Wide Split Level Car Park
The bigger and wider a car park, the more efficient in terms of cars per
square metre. In this case further decks of 16m × 72m have been added to a split
level car park system.
Split Level Car Park with Quick Return Ramp
In this variant of the split level carpark there is another ramp added at the
exit end to speed up exit. Drivers enter and go up by the long way, but go out
the short way. On very large car parks more ramps can be added.
External Ramp
External ramps can spiral round at one or both ends; or along one side
or both sides; or can wrap around 2 or more sides. External ramps can
provide the easiest access and exit solutions, but are not the most
efficient in cost per car or car per square metre.
