Key takeaways

  • A new framework converts flight schedules into passenger arrival-intensity signals for forecasting.
  • A Temporal Fusion Transformer combines these signals with other data for improved accuracy.
  • The model achieved significantly lower forecasting errors than traditional methods at Atlanta Airport.
  • It supports advance staffing and operational planning without needing passenger-flight matching.

Summary

A new framework uses a Temporal Fusion Transformer to convert flight schedules into arrival-intensity signals, significantly improving hourly airport security checkpoint throughput forecasts. The model, tested at Hartsfield-Jackson Atlanta International Airport, achieved a 9.33% weighted mean absolute percentage error for direct six-hour forecasts, outperforming traditional neural networks.

This study introduces an innovative framework for accurately forecasting hourly passenger throughput at airport security checkpoints. The core of the approach involves transforming standard flight departure schedules into temporally aligned signals that represent passenger arrival intensity at security. This is achieved by distributing seat capacity across pre-departure hours using truncated Poisson kernels. These schedule-derived signals are then fed into a Temporal Fusion Transformer, alongside historical throughput data, scheduled activity, and temporal variables. The model demonstrated superior performance at Hartsfield-Jackson Atlanta International Airport, achieving a weighted mean absolute percentage error of 9.33% for direct six-hour forecasts, significantly better than recurrent neural network and long short-term memory models. The framework supports advanced staffing and operational planning without requiring individual passenger-flight matching.

Why it matters

Accurate forecasting of airport security demand allows for optimized staffing, reduced wait times, and improved passenger experience, leading to greater operational efficiency and customer satisfaction in a critical infrastructure sector.

How to implement this in your domain

  1. 1Implement the schedule-informed temporal fusion framework to generate more accurate hourly throughput forecasts for airport security.
  2. 2Integrate these improved forecasts into staffing and lane-opening decision-making processes at airports.
  3. 3Utilize the model's outputs for multi-day checkpoint planning to optimize resource allocation in advance.
  4. 4Collaborate with airport operations and security teams to validate and refine the model's predictions in real-world scenarios.
