Integrated Airside Landside Framework To Assess Passenger Missed Connections with Airport Departure Metering

Airport capacity can be optimized by managing departing and arriving traffic, but this can also have a significant impact on transfer passengers. In particular, the reallocation of departure gates must meet an integrated consideration of landside and airside requirements.

This study was conducted based on data from Singapore Changi Airport. The landside passenger movements in the terminal were simulated under the condition of minimum transfer times. Real runway and apron data (taxiways and apron movements) from the A-SMGCS system were available for the airside simulation. By controlling the aircraft pushback at the gate and the ground movements, the waiting time on the apron can be reduced by up to 12 minutes. However, the aircraft then stand at the gates and prevent reuse by subsequent flights. This increased conflict at the gates delays the gate-in time of an arriving aircraft by an average of 2-7 minutes. Integrated gate reallocation, taking into account transfer passengers, reduces both gate conflicts and passenger delays. In the selected airport environment, a minimum transfer time of 70 minutes is sufficient to significantly reduce the probability of missed connecting flights.
