Passenger Terminal Requirements
Methodology and key assumptions
KEY POINTS
• For the development of
terminal facility
requirements, the ACRP
terminal requirements
model was used. The
ACRP model evaluates
facility requirements of
major functional areas
based on performance
metrics.
• Facility requirements for
the following areas of
the terminal were
determined:
— Apron gates
— Ticketing / Check-in
— Security checkpoint
— Outbound baggage
screening
— Outbound baggage
make-up
— Concessions
— Holdrooms
— Baggage claim
— Restrooms
— Secondary and other
areas
Terminal requirements are driven by forecast aviation demand:
• Based on projected levels of passenger activities at 2.5, 3.0 and 4.0 million annual passengers (MAP)
which is expected to occur around 2018, 2027, and 2042, respectively
• Peak period demand derived from the forecast are used as a basis for sizing the facility requirements.
Number of passengers during the peak hour is shown in Figure 27. Rolling hourly enplaned
passengers are shown on Figure 28.
Development of terminal requirements are based on airport data and industry design standards:
• The industry-standard Airport Cooperative Research Program (ACRP) terminal requirements model
are used to assess the facility requirements for each PAL.
• The ACRP model looks at the major functional areas of both airside and landside terminal operations
to evaluate the facility requirements based on performance metrics such as targeted passenger wait
time and level of service (LOS). Key assumptions were developed from data provided by the Airport,
as well as data collected at other similar U.S. airports.
Level of Service (LOS) is defined as:
• A qualitative and quantitative measurement of comfort experienced by passengers using the airport
terminal facility. The capacity of each element of a terminal facility can vary depending on the level of
crowding and/or processing time that is considered acceptable. Terminal should be designed to
maintain a certain LOS, even during the peak periods of the day, typically chosen as the peak hour of
the average day in the peak month (ADPM). The International Air Transport Association (IATA)
delineates level of service into 6 categories:
1,800
1,600
1,400
1,200
1,000
800
600
400
200

• MAP stands for Million
Annual Passengers, and
includes enplaning and
deplaning passengers.
• LOS C is typically recommended as a design objective since it denotes good service at a
reasonable investment. Therefore, the facilities for DSM are planned for LOS C.
• Some factors that influence LOS for terminal planning are :
– Passenger queuing space
– Target maximum wait time
– Linear frontage (e.g. for baggage claim)
