摘要
为优化终端区空域结构,提高空域运行效率,基于广义跟驰理论和终端区基本运行规则建立了进离场航空器运动模型与空域结构网络模型,仿真分析了等待定位点调整对交通流流量、速度及密度等参数的影响.仿真分析结果表明,交通流对等待定位点位置调整十分敏感,且等待定位点与下游汇聚点的航段长度与进场空中延误具有显著的二次非线性关系,该航段长度越长,交通流速度减小和密度增大越快,进入拥塞状态越迅速,同时拥塞消散越缓慢.
In order to optimize airspace structure and improve its operational efficiency,a motion model for aircrafts departure and arrival and an airspace structure network model are presented based on the generalized following theory and basic operation rules in terminal area.The airspace structure is changed by adjusting the coordinate of Holding Fix point and the influence of airspace structure adjusting on air traffic flow is analyzed by simulation.The simulation results show that the traffic flow is quite sensitive to coordinate adjusting of Holding Fix point.There is an obvious quadratic non-linear relationship between the airplane delay and length of Holding Fix point and downstream convergent point.With this length increased,it is found that the air traffic flows more slowly and the air traffic density increases more rapidly.In addition,the increase of the length would turn the air traffic into congested status more rapidly and make the congestion dissipate more tardily.
