I. Split Level Parking There are various possibilities concerning the traffic flow. You can see some examples in the following pictures. It should be mentioned that the representation of the traffic flow and the ramps refer to cars with left-hand drive in right-hand traffic. For left-hand traffic-operation this representation has to be mirrored accordingly.

This is the usual construction. Perspective: Picture 1-A-I Please click on the picture for enlargement   Picture 2-A-I: Traffic flow via ramps. To see the dimensioning please click on the picture. Further ground plans: Picture 3-A-I Two-way Traffic Double ramps result in a two-way traffic system (see illustration 4-B-I). This should only be preferred when there are extreme “rush hours” in a multi-storey car park, like in office car parks.

Further ground plans: Picture 6-B-I Picture 7-B-I Separate Traffic Flow In picture 8-C-I the lanes for incoming and outgoing cars are separated. The number of parking spaces, along which the incoming cars are led, is high; the traffic flow is simple and clear.

Mixed Traffic Flow The scheme in picture 10-D-I is suitable for a one-way traffic flow, as the traffic is led along all parking spaces. However, this kind of traffic flow can cause jams during rush hours, as the lanes for incoming and outgoing cars are not separated.
