38、ication (DSRC) and global navigation satellite systems (GNSS) both 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 d
39、efine metrics that measure the performance of the system as far as 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 e
40、xamination of the system capabilities both during acceptance and 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 acceptabl
41、e performances although this is not covered in this Technical Specification. This Technical Specification 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 examina
42、tion tests within an Examination Framework depends on the application and the respective context. Compliance with this specification is understood as using the definitions and prescriptions laid out in this Technical Specification whenever the respective system aspects are subjected to performance m
43、easurements, rather than using other definitions and examination methods than the ones specified in this Technical Specification. 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 t
44、he establishment of requirements for EFC systems and their later examination of the charging performance. These charging performance metrics are intended for use with any toll scheme, regardless of its technical underpinnings, system architecture, tariff structure, geographical coverage, or organiza
45、tional model. They are defined to treat technical details that may be different among technologies 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
46、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 inter
47、faces between Toll Service Providers and Toll Chargers as well as information on the end-to-end level. Metrics for the following 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 m
48、etrics which assess the overall performance of the charging process. The proposed metrics are specifically addressed to protect 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.
