The principal bay dimensions are simply the length and width. Default values for these vary according to the vehicle class, service type, and bay angle.
Click on the Bay Dimensions tab.
The window shows the bay dimensions for every combination of service type, vehicle class and bay angle. The default Length and Width are taken from the values for the vehicle class. The Depth (the distance from the baseline to the entrance line) is calculated from simple geometry based upon the bay angle. Any or all values may be over-written with preferred values.
The default 1 Way and 2 Way aisle widths are taken from the values for the service type. They may be over-written with preferred values.
All values taken from the standard are shown in blue, calculated values are shown in red and explicitly entered values are shown in black.
Current parking standards often require that the default values are over-ridden. For example, the aisle width required for angled bays is normally less than that required for 90 degree bays. To change a value, simply click in the field and enter the new value.
