O'Hare International Airport Parking Demand Sensitivity Analysis Forecast

O'Hare has four general public parking areas on the airport containing six separate lots. In the core area grouped together are Lots A, B, and C, which provide 12,030 spaces of structure and surface parking for Terminals 1, 2, and 3; Lot D provides 937 spaces of surface parking for Terminal 5, also known as the international terminal; Lot E is a remote parking lot that provides 6,916 spaces of surface parking; and Lot F is another remote lot that provides 3,118 spaces of surface parking. The total supply of public parking is 23,001 spaces. There is also another remote surface lot available for overflow parking that could accommodate 1,200 vehicles. (This overflow lot was reconstructed and opened to provide full-time operation in early 2002. It provides 2,800 surface spaces to fulfill the unmet demand anticipated to be experienced during the construction of the new parking structures.) Parking demand had become so great that Lots A, B, and C were closing during mid-week because of business travel, and vehicles were being redirected to Lots E and F. In addition, Lots E and F were closing over holiday periods due to pleasure travel, and vehicles were being redirected to the overflow lot.
