基于速度障碍法的飞行冲突网络建模与分析

Modeling and analysis of flight conflict network based on velocity obstacle method

由于依据航空器相对位置关系构建的复杂网络模型未考虑速度、航向等信息,对航空器之间的冲突和空中交通的复杂情况反映能力有限。为解决这一问题,使用速度障碍模型优化飞行状态网络中航空器节点之间的连边和权重,在考虑航空器位置临近的同时,关注航空器的航向与速度状态,使网络能够反映出更多空域系统的内禀属性。通过程序仿真和长水机场雷达数据进行验证,结果表明,该模型相较于飞行状态网络能够更加准确地反映航空器之间的冲突关系和空域的复杂信息,减少飞行冲突的虚警数量,提升网络的信息价值。

Due to the lack of information such as the speed and direction of aircraft,the complex network model based on the relative position relationship has limited ability to reflect the conflicts between aircrafts and the complex situation of air traffic.In order to solve this problem,speed obstacle model is used in this paper to optimize the connection and weight between aircraft nodes in the aircraft state network.While considering the proximity of aircraft to positions,the direction and speed of aircraft are concerned,so that the network can reflect more intrinsic properties of airspace system.Program simulation and verification by radar data of Changshui Airport show that the model in this paper can more accurately reflect the airspace complexity information and the conflict between aircrafts compared with the aircraft state network,so that the number of false alarms for flight conflicts are reduced and the value of network information is improved.
