摘要：

Taxiway is the main resource for airport operation, connecting the runway and apron. The specific traffic flow characteristic emerges with the increase of aircraft at the taxiway. The taxiway traffic flow cell transmission model is established by combining cell transmission model (CTM) and operation regulation of taxiway. Based on the system dynamic simulation platform NetLogo, the model is validated by taking the aircraft taxiway operation at a large airport in China as an example. Then the relationships and phase transition among traffic flow parameters are deduced. The study shows that the taxiway traffic flow transfers among three phases: free, synchronized and block flow. Synchronized flow is very sensitive to the density, where the flux decreases from 0.15 to 0.10 flight/min, velocity decreases from 20 to 7.64 m/s with the increase of density. As the ratio of departure rate and arrival rate decreases from 0.2 to 0.15, the critical value of flux drops from 0.15, 0.10 to 0.13, 0.05 flight/min. The critical value of velocity remains the same in free phase, and drops from 7.64, 1.07 to 0.88, 0.25 m/s for synchronized and block flow. The critical value of density drops from 0.50 to 0.46 flight/km in free phase, but increases from 0.88, 6.21 to 3.77, 13.17 flight/km for synchronized and block flow. The study in this paper reveals the evolution mechanism of taxiway traffic flow congestion, which provides the theory basis for the scientific taxiway management and control strategy. © 2019, Editorial Board of JBUAA.
