摘要
为了揭示汇聚交通场景中冲突风险的总体水平以及动态变化规律,提出了基于蒙特卡罗仿真的汇聚交通流冲突风险评估方法。通过分析汇聚航路的几何特性,构建了汇聚交通流的冲突航段模型,从而确定汇聚交通流产生冲突的范围。并设计了基于蒙特卡罗仿真的冲突风险评估方法,通过实时对比四维轨迹,对冲突率、冲突严重程度、冲突风险、总冲突风险等指标进行了评估,实现了对汇聚交通流从局部到整体,从宏观到微观的冲突风险分析。最后,针对A593航路与R343航路在VMB点汇聚的实际汇聚交通场景,在分析实际运行数据分布的基础上对其冲突风险进行了评估。
In order to unveil the overall states and dynamic variation of conflict risks for converging air traffic,a conflict risk assessment method based on Monte Carlo simulation was proposed.Based on the analysis of the geometry characteristic of the converging airways,the conflict route segment model is proposed to determine the conflict ranges that are caused by converging air traffic.The conflict risk assessment method based on the Monte Carlo Simulation was designed.The conflict risks of converging air traffic were assessed from macroscopic and microscopic levels by comparing the 4Dtrajectories,conflict rate,conflict severity,conflict risk and total conflict risks.Finally,the conflict risks were assessed for the convergence of Route A593 and Route R343 at VMB by the simulation as an example based on statistical analysis of historical operation data.
