基于三维轨迹管的终端区交通流潜在冲突识别
Potential Conflict Identification of Terminal-Area Traffic Flow Based on Three-Dimensional Trajectory Tube Structures
摘要
Abstract
With the rapid development of aviation industry,the density of terminal-airspace traffic has increased significantly,resulting in higher potential conflict among aircraft.To address this issue,this study proposes a potential conflict identification method for terminal airspace based on three-dimensional(3D)trajectory tube structures.The approach first clusters arrival trajectories to identify major traffic flows and constructs corresponding 3D trajectory tubes.It then introduces traffic-flow parameters into a probabilistic model,which is combined with three-dimensional airspace gridding to identify and locate potential conflict regions.The results demonstrate that the proposed method can effectively detect potential conflict areas within a 15 min time window and analyze the interactions among traffic flows within these regions.This research provides a valuable framework for improving the safety and efficiency of terminal airspace operations,offering both theoretical and practical significance for airspace optimization and decision-support enhancement.关键词
