基于Netlogo的终端区进场交通流建模与仿真

终端区进场交通流特性参数研究对于解决复杂空域结构下航空器拥堵、航班延误具有重要的实际意义。基于元胞传输模型将进场航线划分元胞，并且在数理推导的基础上，基于Netlogo仿真建模平台搭建进场交通流元胞传输模型仿真环境，对进场交通流的宏观涌现行为进行仿真模拟，得到交通流基本参数速度、流量、密度之间演变趋势。研究结果表明，终端区进场交通流三大基本参数之间存在明显的数量关系，关系曲线相对应分为自由流、拥挤流和阻塞流三种状态，并且受到管制间隔、飞行程序、管制策略的影响。利用相关研究成果，可通过改变管制策略、调整管制间隔、优化飞行程序的方法使得交通流特性向着可预知的方向演变，因此对终端区交通态势的判断具有应用价值。

Characteristics Analysis of Arrival Traffic Flow in Terminal Area Based on Cell Transmission Model

Research on characteristics of approach air traffic flow in terminal area is of great significance to alleviate air traffic congestion under a complex aerospace. This paper divided approach pattern into cells based on cell transmission model,combined with mathematical induction,construct a terminal arri-ving traffic flow model based on a multi-agent simulation tool-Netlogo. Simulate the macroscopic burst behavior of the traffic flow,eventually get the evolution trend of the relationship between the speed,traffic flow and density The results show that the three of the basic parameter of the terminal approach traffic have an obvious quantity relationship with each other, relation curves are divided into three different states,they are free flow, congestion flow and blocked flow, which affected by control separation, flight procedure and control strategies. Results from this paper can make it possible that traffic flow goes as what we expect by changing the control strategies,adjusting control separation and optimizing flight procedures. Therefore,it has great value of practical application for estimating terminal traffic states.
