区域多扇区耦合容量评估

ACC Sectors Coupled Capacity Assessment

明确空域单元内部交通流特性及其动态演变机制是评估区域多扇区耦合通行能力的基础,对于提升空中交通管理效率至关重要。基于改进的元胞传输模型(CTM),以实际飞行数据为基增量仿真推演分析了交通流流量、速度与密度间的宏观基本图(MFD)。进一步表征区域多扇区之间的耦合作用,建立区域多扇区耦合快时仿真模型。通过分析区域多扇区需求平均延误关系对区域多扇区耦合容量进行评估,揭示区域运行瓶颈。以合肥区域管制扇区为例,评估了区域多扇区耦合容量,并依据各扇区的延误贡献识别了该区域多扇区运行瓶颈主要集中在ZSOFAR02扇区和ZSOFAR01扇区。研究成果可为提高区域多扇区航路航线网络通行能力提供科学的理论支撑。

Clarifying the characteristics of traffic flow within a specific airspace sector and its dynamic evolution mechanism is fundamental for assessing the coupled traffic capacity of multiple sectors in a region,which is crucial for enhancing the efficiency of air traffic management.Based on the improved Cell Transmission Model(CTM),this paper uses actual flight data for incremental simulation to analyze the macroscopic fundamental diagram(MFD)of traffic flow,velocity,and density.Furthermore,it characterizes the coupling effect between multiple sectors in the region and establishes a regional multi sector coupled rapid simulation model.By analyzing the demand average delay relationship in regional multi sectors,the coupled capacity of multiple sectors is assessed,revealing the operational bottlenecks of the region.Taking the Hefei area control sectors as an example,the coupled capacity of multiple sectors is evaluated,and the main operational bottlenecks in the region are identified as being primarily concentrated in the ZSOFAR02 and ZSOFAR01 sectors.The research results can provide scientific theoretical support for improving the traffic capacity of the regional multi sector air route network.
