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

Table 1

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 mean (standard deviation), calculated across square facilities with sides 100′ to 1000′ in 1′ increments.

	Human “small”	Human “large”
AV “front-in”	+10.9% (6.9%)	+15.0% (7.1%)
AV “reverse-in”	+34.2% (7.9%)	+39.1% (8.1%)
AV “toing/froing”	+40.8% (8.3%)	+45.9% (8.5%)
AV “translation”	+44.0% (8.5%)	+49.3% (8.7%)
