作为空中交通管理 (ATM) 自动化工具的核心组件之一，轨迹预测器对 ATM 自动化乃至 ATM 系统的性能具有重大影响。在之前的努力的基础上，本文应用了一个框架来协助开发轨迹预测器的性能指标。根据现有轨迹预测器 (TP) 性能评估，定义了轨迹预测的关键性能区域。输入和输出指标的准确性关键性能区域中描述了基本指标。基本指标依赖于事件的精确定义。讨论了与事件定义相关的问题，并提供了处理这些问题的方法。定义说明符是为了进一步细化所有性能领域的指标定义。通过借鉴文献中的例子来说明基本指标、事件和说明符的应用。提供了轨迹预测精度对冲突探测性能影响的示例，以说明在开发 TP 性能指标时必须考虑对更高级别系统的影响。
As one of the central components of air traffic management (ATM) automation tools, trajectory predictors have a significant impact on the performance of ATM automation and hence the ATM system. Building on prior efforts, this paper applies a framework to assist in the development of performance metrics for trajectory predictors. Key performance areas are defined for trajectory prediction based upon existing trajectory predictor (TP) performance evaluations. Basic metrics are described within the accuracy key performance area for both input and output metrics. The basic metrics rely on precise definitions of events. Issues associated with the definition of events are discussed and approaches are provided for dealing with these. Specifiers are defined to further refine the definition of metrics in all performance areas. The application of basic metrics, events and specifiers is illustrated by drawing upon examples from the literature. An example of the impact of trajectory prediction accuracy on conflict probe performance is provided to illustrate considerations that must be given to the impact on higher-level systems when developing metrics for TP performance.
