机场飞行区飞行轨迹数据库

机场飞行区飞行轨迹数据主要由国家重点研发计划项目 “机场飞行区绿色运行环境治理技术”（项目编号：2022YFB2602000）自可题4“降噪减排多目标约束下的终端区飞行程序协同优化方法研究”所研制的多模式机场群协同运行下的异质交通流冲突预警原型系统提供，通过由交通大数据联合研究中心（中国民航科学技术研究院）所获得的某机场运行航班数据等初始数据经过进行加工处理后获得，主要包括航班运营机型，航迹空间信息、速度、高度等。该类数据反映了某机场终端区航迹分布情况，可用于辅助研究交通运行态势分析、空域运行状态评估、交通流调配策略制定等内容

Airport flight zone flight trajectory data is mainly provided by the prototype system for heterogeneous traffic flow conflict warning under multi-mode airport cluster collaborative operation, developed by Sub-topic 4 "Research on Collaborative Optimization Method of Terminal Area Flight Procedures under Multi-objective Constraints of Noise Reduction and Emission Reduction" of the National Key R&D Program of China project "Green Operation Environment Governance Technology for Airport Flight Zones" (Project No. 2022YFB2602000). The data was obtained by processing initial datasets including flight operation data of a specific airport acquired through the Joint Research Center for Traffic Big Data (China Academy of Civil Aviation Science and Technology). It mainly covers aircraft types used in flight operations, spatial trajectory data, speed, altitude, and other related operational parameters. This dataset reflects the trajectory distribution within the terminal airspace of the specific airport, and can support research in areas including traffic operation situation analysis, airspace operation status assessment, and traffic flow allocation strategy formulation, among other related research topics.
