DART (Data-driven AiRcraft Trajectory prediction research) addresses the topic “ER-02-2015 – Data Science in ATM” exploring the applicability of data science and complexity science techniques to the ATM domain. DART delivers an understanding on the suitability of applying big data and agent –based modelling techniques for predicting aircraft trajectories based on data-driven models and accounting for ATM network complexity effects, considering multiple correlated trajectories.
