Abstract

This paper explores the optimization of Ground Delay Programs (GDP), a prevalent Traffic Management Initia- tive used in Air Traffic Management (ATM) to reconcile capacity and demand discrepancies at airports. Employing Reinforce- ment Learning (RL) to manage the inherent uncertainties in the national airspace system—such as weather variability, fluc- tuating flight demands, and airport arrival rates—we developed two RL models: Behavioral Cloning (BC) and Conservative Q-Learning (CQL). These models are designed to enhance GDP efficiency by utilizing a sophisticated reward function that integrates ground and airborne delays and terminal area congestion. We constructed a simulated single-airport envi- ronment, SAGDP ENV , which incorporates real operational data along with predicted uncertainties to facilitate realistic decision-making scenarios. Utilizing the whole year 2019 data from Newark Liberty International Airport (EWR), our models aimed to preemptively set airport program rates. Despite thor- ough modeling and simulation, initial outcomes indicated that the models struggled to learn effectively, attributed potentially to oversimplified environmental assumptions. This paper discusses the challenges encountered, evaluates the models’ performance against actual operational data, and outlines future directions to refine RL applications in ATM.
