O'HARE INTERNATIONAL AIRPORT PARKING DEMAND SENSITIVITY ANALYSIS FORECAST

摘要

In early 2000, the City of Chicago's Department of Aviation (CDOA) unveiled an ambitious capital improvement program for O'Hare International Airport termed the World Gateway Program (WGP), which would basically add two new terminals and reconfigure the utilization of the existing terminals. The WGP would modify the distribution of the major airline carriers and their alliances among the terminals, and thereby would likely affect where passengers would wish to park their vehicles. It was essential to perform a sensitivity analysis forecast to determine the amount and locations of parking demand under the proposed WGP. Furthermore, in the years leading up to the announcement of the WGP, the demand for public parking at O'Hare had nearly exceeded the available supply because of the growth in air travel and other factors. The need to construct additional parking facilities was imminent. The original report that was the basis for this paper was completed in December 2000. (Kitsakos et al., 2000). 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.
