摘要
面向空中交通流场景中异质航空器运行安全及稳定性的需求,提出了一种全新的异质航空器跟驰行为模型,促使异质交通流更加安全和稳定地运行.首先,考虑了空中交通流中同向飞行的前后航空器之间的间距变化,以及后机自身当前与历史时间的速度差,更好地描述了跟驰行为中的非线性运动现象;然后,采用稳定性分析方法对异质航空器跟驰模型的稳定性进行了推导和分析,得出了初始纵向飞行间隔与后机反应敏感度之间的关系;最后,验证结果表明,该模型能够使后机更快地达到新的目标速度,与前机形成新的稳定跟驰状态,能够有效地缓解交通拥堵,具有广阔应用前景.
Abstract
Aiming at the requirements of safety and stability of heterogeneous aircraft operation in air traffic flow scenarios,a new heterogeneous aircraft following behavior model is proposed to promote safer and more stable operation of heterogeneous traffic flow.Firstly,the changing spacing between the front and rear aircraft flying in the same direction in air traffic flow is considered,as well as the speed difference between the current and historical time of the following aircraft,it better describes the nonlinear motion phenomenon in the following behavior.Then,the stability analysis method is used to derive and analyze the stability of the heterogeneous aircraft following model,the relationship between the initial longitudinal flight interval and reaction sensitivity of the following aircraft is obtained.Final-ly,the verification results show that the model can enable the following aircraft to reach the new target speed faster and form a new stable following state with the leading aircraft,it can effectively alleviate traffic congestion and has broad application prospects.
