31、h subject to a certain random behaviour that may affect the computation of the charges. Thus, in order to protect the interests of the different involved stakeholders, in particular Service Users and Toll Chargers, it is essential to define metrics that measure the performance of the system as far a

32、s computation of charges is concerned and ensure that the potential resulting errors in terms of size and probability are acceptable. These metrics will be an essential tool when establishing requirements for the systems and also for examination of the system capabilities both during acceptance and

33、during the operational life of the system. In addition, in order to ensure the interoperability of different systems, it will be necessary to agree on common metrics to be used and on the actual values that define the required acceptable performances although this is not covered in this document. Th

34、is document is defined as a toolbox standard of examination tests plus a method for defining and documenting Specific Examination Frameworks to meet specific needs. The detailed choice of the set of examination tests within an Examination Framework depends on the application and the respective conte

35、xt. Compliance with this specification is understood as using the definitions and prescriptions laid out in this document whenever the respective system aspects are subjected to performance measurements, rather than using other definitions and examination methods than the ones specified in this docu

36、ment. ISO/TS 17444-1 defines a set of charging performance 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. These charging per

37、formance metrics are intended for use with any toll scheme, regardless of its technical underpinnings, system architecture, tariff structure, geographical coverage, or organizational model. They are defined to treat technical details that may be different among technologies as a “black box”. They fo

38、cus 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 co

39、mparable 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 and Toll Chargers, as well as information on the end-to-end level. Metrics for the fo

40、llowing information exchanges are defined: Charge Reports; Toll Declarations; Billing Details and associated event data; Payment Claims on the level of user accounts; End-to-End Metrics which assess the overall performance of the charging process. The proposed metrics are specifically addressed to p

41、rotect the interests of the actors in a toll system, such as Toll Service Providers, Toll Chargers and Service Users. The metrics can be used to define requirements (e.g. for requests for proposals) and for performance assessment. ISO 2017 All rights reserved vii ISO/TS 17444-2:2017(E) Toll schemes

42、take on various forms as identified in the ISO 17575 series and ISO 14906. In order to create a uniform performance metric specification, toll schemes are grouped into two classes based on the character of their primary charging variable: charging based on discrete events (charges associated to the

43、fact that a vehicle is crossing or standing within a certain zone); those based on a continuous measurement (duration or distance). In all these toll schemes, tolls may additionally vary as a function of vehicle class characteristics such as trailer presence, number of axles, taxation class, operati

44、ng function, and depending on time of day or day of week, such that, for example, tariffs are higher in rush hour and lower on the weekends. With this degree of complexity, it is not surprising to find that the attempts to evaluate and compare technical solutions for Service User charging have been

45、made uniquely each time a procurement or study is initiated, and with only limited ability to reuse prior comparisons made by other testing entities. Examination Framework The Examination Framework that is defined in this document is designed for measuring the metrics defined in ISO/TS 17444-1. The

46、general aim is to achieve a maximum comparability and reproducibility of the results without restricting the technological choices in system design. Specific Examination Frameworks may be defined for the Evaluation and Monitoring Phases of a project due to the differences in the availability of equi

47、pped vehicles. Evaluation Phase This phase encompasses system evaluation and selection, as well as commissioning and ramp up during implementation. Important aspects of this phase are relatively small sample sizes, and well controlled behaviour of test vehicles. Monitoring Phase After the system has

48、 gone into operation, its behaviour needs to be monitored for several reasons, such as fine-tuning of the system performance, monitoring of SLAs between contractual partners (supplier, Toll Charger, Toll Service Provider, etc.). In this phase, the following system aspects can be expected: very large

49、 sample sizes possible, but with unknown behaviour of the vehicles; in principle all measurements from implementation phase possible, too.
