Capacity Impacts and Optimal Geometry of Automated Cars’ Surface Parking Facilities

Table 2

Percentage difference in parking capacity between two human parking space dimensions (“small” and “large”) and dimensions required for the four AV maneuvers (“front-in,” “reverse-in,” “toing/froing,” and “translation”). Values in each cell represent percentage differences for rectangles with   having the same area as square facilities with sides of 250′  × 250′ (62,500 sq. ft.), 500′  × 500′ (250,000 sq. ft.), and 1000′  × 1000′ (1,000,000 sq. ft.).

	Human “small”	Human “large”
AV “front-in”	+3.8%, +6.2%, +7.5%	+6.7%, +10.5%, +11.7%
AV “reverse-in”	+28.6%, +33.9%, +27.1%	+32.2%, +39.3%, +32.1%
AV “toing/froing”	+28.6%, +39.6%, +37.3%	+32.2%, +45.3%, +42.7%
AV “translation”	+53.5%, +52.2%, +43.2%	+57.8%, +58.4%, +48.9%
