Chicago O’Hare International Airport
L&B’s study involved the development and simulation of new security screening checkpoint (SSCP) arrangements for Terminal 5 (T5) at Chicago O’Hare International Airport (ORD). The new SSCP at T5 is designed to maximize concession revenue while maintaining a high level of service (LOS) when processing passengers.
At the start of the study, L&B administered field observations of current passenger activity at the SSCP aimed at understanding the behavior of passengers utilizing the existing facilities. Results were then used to calibrate the simulation model to depict these existing conditions as closely as possible yielding reliable results when applied to anticipated future demand.
The operational assessment utilized computer simulation software (ARCport) to analyze the movement and LOS of passengers processing through the existing and preferred SSCP configuration, as well as analyzing different impacts that changes in TSA staffing will have on passenger throughput, queue lengths, and wait times.
