TÓM TẮT
Previously, we can possibly describe the dynamics of every aircraft in the airspace using Lagrangian method. Airspace traffic models using Lagrangian method might have high accuracy in terms of predicting the trend of the air traffic flow. The most significant disadvantage of those models is that they require a lot of computational effort (due to the spherical surface of the Earth and the complexity in the dynamics of aircraft). Recent research shows that Eulerian method is a potential approach for modeling the airspace traffic. Models using Eulerian method can be simple, low-order, and computational friendly besides providing reasonable accuracy. In this paper, we first revise some popular models using Eulerian method in order to extract the strong points of these models. Secondly, we propose a systematic approach to form an improved version of the Modified Cell-Transmission Model. The proposed model maintains the advantages of existing models such as vector-based aircraft count state, low-order system, while it can still cover a larger air area.
