随着交通流量的增加，为了提高空域通行能力和减少延误，需要降低间隔标准。减少的间隔最小值如果被证明是安全的，就可以应用于空中交通管理，因此对不同垂直间隔的碰撞风险进行了评估，以满足目标安全水平。建立了垂直间隔的碰撞风险模型，并推导了计算方法。最后，讨论了垂直间隔对碰撞风险的影响，结果表明，如果垂直间隔最小降到300m，碰撞风险满足安全要求，随着交通流量的增加，碰撞风险在未来15年内保持安全水平。
With the increasing traffic flow,the separation standard is required to be reduced in order to enhance airspace capacity and decrease delays.The reduced separation minima is able to be applied to the air traffic management if it is proved to be safety,so collision risk for different vertical separation is evaluated in order to meet the target level of safety.A vertical collision risk model is established and the calculation methods are deduced.Finally how the vertical separation influence collision risk is addressed and the results show that the collision risk meets the safety requirements if vertical separation minima are reduced to 300 meters,and the collision risk maintains safety level in the next fifteen years with the increasing traffic flow.
