FACILITY REQUIREMENTS Terminal Curb Roadways The key intermodal transfer between ground-mode and aviation-mode takes place at the terminal curb. In Eugene, this transfer, for dropping off departing passengers at ticketing/check-in, or picking up arriving passengers at bag claim, takes place on two parallel roadways. Adjacent to the terminal is the inner curb 12 roadway, three lanes wide, with 240 feet of legal, usable length at check-in, and 248 feet of legal, usable length at bag claim. This curb is predominantly used by privately owned vehicles (POVs), though commercial modes may drop passengers off at ticketing/check-in. The outer curb roadway (nominally three lanes, though with a single lane for access, egress, and across the center crosswalk) is reserved for the commercial modes, predominantly for pick-up. Spaces are designated for taxis (both pre-arranged and available-on-demand), Omni Shuttle, motor coaches (buses), and hotel and resort shuttles. The commercial vehicles wait in these zones in addition to actively loading passengers. Terminal curb roadway requirements are a function of the physical characteristics of the curbs (lengths, number and arrangement of lanes, number and width of crosswalks) and of the operational characteristics of the curb. Operational characteristics actually have a higher degree of influence on capacity, level of service, and therefore facility requirements, than do the physical characteristics of the curb. Key operational influences include the volume and location of pedestrians crossing the curb, the nature of traffic control (e.g., presence of STOP signs) on the curb, and especially, the volume and characteristics of the demand of vehicles, and how they are managed by airport staff or, at some airports, police. The greater the number of vehicles, and/or the longer they dwell at the curb to service passengers, the lower the capacity and level of service of the curb roadway. 3.7.2.1Inner Curb Roadway Table 3-23 presents the critical data used in, and the results of, the analysis of the inner curb roadway at Eugene under current (peak hour of the average day of the peak month – PH ADPM) conditions, and under the similar condition at the future planning activity levels (PALs 1 – 3). The volumes of vehicles (per hour) include those which stop to serve (drop-off or pick-up) a passenger, and those which pass by a curb as a “thru” vehicle. As is true for any linear curb at a single-level terminal, all vehicles stopping to drop off at departures are thru vehicles on the downstream arrivals curb, and all vehicles stopping to pick up at arrivals are thru vehicles on the upstream departures curb. At Eugene, however, there are additional thru vehicles due to the fact that all rental cars exiting the Airport leave by driving as thru vehicles across both the departures and arrivals curbs. Finally, a small number of thru vehicles on both curbs are those which are recirculating on Douglas Drive while waiting to pick up an arriving passenger. The more occupied the arrivals curb, the higher the number of such unnecessary thru vehicles. Thru vehicles reduce capacity, though not as much as stopped vehicles. The curb is analyzed both with and without the thru volumes, and an overall level of service is estimated, which is the critical value in the table. 12 Except at the center crosswalk, where there are two continuous lanes.
