The invention discloses a limited airspace unit identification method based on a DBSCAN clustering algorithm. The method comprises the following steps: firstly, defining an airspace unit; secondly, collecting actual flight operation data and corresponding air route information, and matching the air route information with longitude and latitude coordinate data of an airspace unit to construct an air route network model; then, calculating flight delay data, downsampling the data, and associating the data with an airspace unit to obtain flight delay feature data; and finally, constructing an identification model of the limited airspace unit based on a DBSCAN clustering algorithm in combination with the airway network model and the flight delay characteristics. The limited airspace unit and the limited starting and ending time can be identified, and randomness caused by severe weather, air traffic control and other events can be solved. The starting time and the ending time of airspace limitation are determined, direct flight delay and delay caused by propagation can be separated, the propagation mechanism of flight delay is further explored, and the method has important significance in improving the accuracy of flight delay prediction.

    本发明公开了一种基于DBSCAN聚类算法的受限空域单元识别方法,该方法首先对空域单元进行定义;其次,收集航班实际运行数据与其对应的航路信息,将航路信息与空域单元的经纬度坐标数据相匹配构建航路网络模型;然后,计算航班延误数据,对数据降采样,并与空域单元进行关联得到航班延误特征数据;最后,结合航路网络模型与航班延误特征,基于DBSCAN聚类算法构建受限空域单元的识别模型。本发明方法可以识别受限空域单元和受限的起止时间,有助于解决恶劣天气、空中交通管制等事件引起的随机性。确定空域受限的起始时间和结束时间,可以将航班直接延误与传播引起的延误分开,进一步探索航班延误的传播机理,对提高航班延误预测的准确性具有重要意义。
