标准范围

ISO/TS 17444-1:2017定义了电子收费（EFC）系统在与收费计算相关的错误水平方面的收费性能指标。ISO/TS 17444-1:2017是量度的工具箱标准。度量的详细选择取决于应用程序和各自的上下文。ISO/TS 17444-1:2017描述了一组具有适当定义、原则和公式的指标，这些指标共同构成了一个参考框架，用于制定EFC系统的要求，以及随后对充电性能的检查。ISO/TS 17444中定义的充电性能指标-1:2017适用于任何收费方案，无论其技术基础、系统架构、电价结构、地理覆盖范围或组织模式如何。它们被定义为将技术细节视为“黑匣子”，这些细节可能因技术和供应商而异，也可能随时间而变化。它们只关注充电过程的结果，即相对于预先测量或理论上正确的量的充电量，而不是来自传感器等各种组件的中间变量，如定位精度、信号范围或光学分辨率。这种方法确保在所有相关情况下，每个指标的结果都具有可比性。这些指标旨在涵盖前端接口上交换的信息，以及收费服务提供商、收费员和道路用户之间以及端到端层面上的互操作性接口。

ISO/TS 17444-1:2017 defines metrics for the charging performance of electronic fee collection (EFC) systems in terms of the level of errors associated with charging computation.ISO/TS 17444-1:2017 is a toolbox standard of metrics. The detailed choice of metrics depends on the application and the respective context.ISO/TS 17444-1:2017 describes a set of metrics with appropriate definitions, principles and formulations, which together make up a reference framework for the establishment of requirements for EFC systems and their later examination of the charging performance.The charging performance metrics defined in ISO/TS 17444-1:2017 are intended for use with any Charging Scheme, regardless of its technical underpinnings, system architecture, tariff structure, geographical coverage, or organizational model. They are defined to treat technical details that can be different among technologies and vendors or vary over time as a "black box".They focus solely on the outcome of the charging process, i.e. the amount charged in relation to a pre-measured or theoretically correct amount, rather than intermediate variables from various components as sensors, such as positioning accuracy, signal range, or optical resolution. This approach ensures comparable results for each metric in all relevant situations.The metrics are designed to cover the information exchanged on the Front End interface and the interoperability interfaces between Toll Service Providers, Toll Chargers and Road Users as well as on the End-to-End level.
