Abstract EN
To be different from the traditional concept of congestion, congestion propagation based on the correlation between aircraft is given.
And the main resource shared and competed for in airspace is the air route network, especially the intersection linking the multiroute.
The system composed of congestion propagation units operates in airspace network, which is limited by the network geometry and the correlation between aircraft.
This paper presents models based on the congestion and propagation characteristics in complex network, predicting the trend of congestion propagation and the peak of congestion size.
By analyzing the relationships between system parameters and congestion propagation and accounting for the effects of propagation across networks, this paper enhances the current dynamics models of congestion propagation in airspace.
Firstly, a heterogeneous network model is introduced to reveal the propagation process of aircraft with different degrees of correlation.
This is followed by the specification of two simplified models for short-term prediction, just taking the sector capacity, propagation rate, and dissipation rate into account.
And the propagation rate and dissipation rate depend on the sector geometry and aircraft distribution.
Using them (sector capacity, propagation rate, and dissipation rate), the prediction models are accurate in predicting the evolution of congestion peak and propagation trend in comparison with the sample data of intersections in the sector.
Of them, the model with capacity limitation is more accurate on busy hour.
And on non-busy hour, capacity is insensitive in predicting congestion clusters.
Furthermore, the computing method of propagation rate and dissipation rate is given in our paper.
Finally, a numerical analysis is performed, in which it is demonstrated that system capacity, propagation rate, and dissipation rate have different effects on congestion propagation in airspace.
The results show that low propagation and high dissipation rates not only are nonlinear but also decrease the level of congestion in the propagation of congestion.
In particular, of the three parameters, system capacity affects the rate of convergence, with a low-capacity system reaching a stable state quickly and therefore providing a basis for sector partitioning.
The method proposed in this paper should enable air traffic controllers to better understand the characteristics of congestion and its propagation for the benefits of both congestion management and improvement of efficiency.
Significantly, airspace designers can take congestion propagation into consideration for optimizing the airspace structure in the future.
