Application of simulation models in airport facility design

Lester B. Pearson - Toronto International Airport is undertaking a $4.4B development program comprising a new 390000 sq. m. terminal building (replacing two aging terminals), three new runways, cargo facilities, a central utilities plant, and an expanded road system and parking facilities. This activity is proceeding while the airport continues to operate and while requirements evolve in response to rapid changes in the airline industry. The airport has used and continues to use airport simulation models to assist in the development of program requirements and to validate design. For example, computer models have been used to generate population estimates to determine impacts on HVAC requirements and to simulate queuing at check-in counters and pre-board security screening points. This paper discusses calibration methods and the application of simulation results in the design process. Finally, the impact of the changed environment since September 11, 2001 on airport design is discussed.
