空中交通流特性分析是空中交通流理论研究的重要内容,是空中交通管理的重要依据。基于终端区交通流混杂动力特征,采用模糊逻辑方法提出了航空器动态期望间隔控制策略,运用“刺激-反射”跟驰理论和局域先到先服务(FCFS)的原则建立了终端区交通流广义跟驰模型,并基于NetLogo构建了终端区交通流多智能体仿真平台,结合广州白云机场(ZGGG)02R跑道进场实例,演析了终端区进场交通系统涌现行为,揭示了交通流的速度、密度和流量3个基本参数之间的相互关系,发掘了空中交通蕴含的自由态、畅行态、亚稳态、伪拥塞态和同步态等5个演变相态,剖析了不同交通组织、间隔标准和流控策略下交通流的相变规律。研究成果可为丰富完善空中交通流理论奠定部分基础,为科学管控空中交通提供重要基础支撑。
Air traffic flow characteristics analysis is an important part of the study of air traffic flow theory and an important basis for air traffic management. Based on the hybrid dynamic characteristics of traffic flow in terminal area, the dynamic expectation interval control strategy of aircraft is proposed by using fuzzy logic method. The terminal traffic is established by the principle of “stimulus-reflection ” car-following theory and local first come first served (FCFS) Flow generalized car-following model, and based on NetLogo, a simulation platform of terminal traffic flow multi-agent is constructed. Based on the example of entering runway 02R of Guangzhou Baiyun Airport (ZGGG), the emergence behavior of traffic system in terminal area is analyzed and the traffic flow Velocity, density and flow of the three basic parameters of the relationship between the excavated air traffic contains free state, smooth state, metastable state, pseudo-congested state and synchronous state of five evolution phase, analysis of different traffic organizations , Interval standard and the flow control law under the traffic flow of the law of phase transition. The research results lay a foundation for enriching and improving the air traffic flow theory and provide an important foundation for scientific control of air traffic.
