基于Event的垂直碰撞风险改进模型研究

摘要

空中交通流量的快速增长,导致空域资源紧张和大量航班延误.使用新航行技术缩小间隔标准可以有效地缓解上述问题.因此,对航路的碰撞风险进行评估具有重要意义.传统Event模型的碰撞模板是一个长方体模板,本文在前人研究的基础上提出了用椭球体代替长方体碰撞模板的思想,并对飞机穿越垂直间隔片的概率重新进行计算.结果表明,在相同条件下改进后的Event碰撞风险模型是原模型碰撞概率的53.38％,改进的碰撞风险评估模型更加精确合理.%With the rapid growth of air traffic flow, airspace resource is strained and large number of flights delay. Using new traffic technology to reduce the separation standard can effectively solve this problem. Therefore, it is meaningful to assess the route collision risk. Traditional Event model is based on rectangular collision risk model. In this paper, using the ellipsoid collision model instead of a rectangular collision model and re -calculated the probability of the aircraft through the vertical separation sheet. The results show that, under the same conditions improved Event collision risk model is 53.38% compared to the original model, improved assessment of collision risk model is more accurate and reasonable.
