摘要: 深入研究场面交通的复杂特性可以提高机场场面交通仿真模型的可靠性。在NS(NaSch)模型基础上,提出一种改进模型。新模型考虑了滑行时的随机因素和交叉口处的交通特性,并在交叉口处增加连接元胞来连接两个演化规则不同的路段,连接元胞的状态代表下一路段的飞机占用信息。大量仿真实验表明,仿真值与真实值的吻合度提高了13%,从流量与到达率的关系、密度与平均速度和平均流量的关系以及时空图等方面验证了新模型的可靠性和准确性,该模型可用于计算、推演和预测机场场面交通的运行态势。

Abstract: To increase the reliability of the airport scene traffic simulation model, the complex characteristics of scene traffic are researched. An improved model based on NS model is proposed. The influence of the stochastic factors on the taxiing process and the traffic characteristics at the intersection are considered, and the new cells are added to connect the two sections with different evolution rules. The state of the connected cells represents the occupancy of the next section. A large number of simulation experiments were processed, and the results show the goodness of fit between the simulation values and true ones increased by 13%. The reliability and accuracy of the model were verified by the relationship between flight flow and arriving rate, the relationship among flight flow density, average velocity and average flow, and the space-time map. The model can be used to calculate, deduce and predict the operation situation of airport traffic.

Key words: airport scene traffic, NaSch (NS) model, connected cell, evolution rule, cellular automaton
