45 Common Disadvantages A common disadvantage among the APPF alternatives is that the facilities would be constructed in what is likely an already congested central terminal area, which would result in high construction costs and potentially significant opera- tional disruptions. In the case of Alternative 4, it may be that a support facility of this scope would replace too many ter- minal functions, leading to large amounts of redundant space and roadway capacity. Because more passenger processing would be occurring in an adjacent facility, each alternative may result in longer walking distances because passengers are required to cross a roadway or take an elevated walkway crossing to reach their desired locations. Alternative 4 would likely require that POVs and CVs be inspected because of the large numbers of pedestrians in the facility, which would in- volve passenger inconvenience and increased operating costs. Alternatives Evaluation Two sets of criteria were developed to evaluate the alterna- tives. The first set of criteria relates to passengers; the second set of criteria relates to feasibility of implementation.

47 Figure 5-6. APPF concept example--section. POV departing passenger drop-off would occur on an upper level of the structure, and POV arriving passenger pickup would be accommodated on a lower level. In this example, CV passenger pickup and drop-off would be accommodated at the terminal building curbside. The POV passenger drop-off area would be connected directly to the terminal via a pedestrian bridge. The elevation of the pedestrian bridge and the location of the POV curbsides would vary depending upon the config- uration of the terminal building and curbside roadway system. The APPF conceptual layout of the upper-level facilities is shown in Figure 5-7. POVs destined for the passenger drop-off areas would have the option of accessing the bag-check plaza to check-in for their flight and drop off their baggage. POVs would then proceed to the supplemental curbside located in the parking structure for passenger drop-off. In this example, a passenger assistance parking area accessed directly from the POV passenger drop-off curbside is provided to accommodate passengers desiring assistance in unloading (limited to 10- to 15-min dwell times). In addition, direct access to a short-term parking area (e.g., 1-hr parking) is also provided via the POV Figure 5-7. APPF concept example--upper level. passenger drop-off roadway.
