ISO 17575-1:2016定义了自动收费方案中前端（OBE加可选代理）和相应后端之间数据交换的格式和语义。它定义了用于生成包含特定时间间隔内车辆道路使用信息的充电报告的数据元素，这些数据元素从前端发送到后端。它还定义了可用于重新配置前端收集费用相关信息的持续过程的数据。范围如图1所示。 充电报告的构成取决于假定存在于前端的配置数据。可根据当地需求为每个单独的收费方案配置收费报告汇编。 根据ISO 17575本部分生成的充电报告符合ISO 17573:2010中定义的建筑概念的要求。 ISO 17575-1:2016中的定义包括 -报告数据，即用于将道路使用数据从前端传输到后端的数据，包括从后端到前端的响应， -用于支持安全机制的数据， -合同数据，即用于识别合同重要实体的数据， -道路使用数据，即用于报告道路使用量的数据， -用于管理支付账户的账户数据， -数据版本控制，以及 -合规性检查数据，即从ISO 12813:2015导入的数据，合规性检查通信中需要这些数据。 附录A包含使用ASN的数据类型规范。1.符号。 附录B中提供了协议实施一致性声明（PICS）形式。 附录C提供了第7条所述数据元素结构的图形表示。 附录D提供了ISO 17575的本部分如何在EETS环境中使用的信息，以及本标准如何满足欧盟第2009/750号决定中规定的要求。

ISO 17575-1:2016 defines the format and semantics of the data exchange between a Front End (OBE plus optional proxy) and corresponding Back Ends in autonomous toll schemes. It defines the data elements that are used to generate charge reports containing information about the road usage of a vehicle for certain time intervals, sent from the Front End to the Back End. It also defines the data that can be used to re-configure the ongoing process of gathering charge relevant information in the Front End. The scope is shown in Figure 1. The constitution of the charge report is dependent on configuration data that are assumed to be present in the Front End. The assembly of charge reports can be configured for each individual toll scheme according to local needs. Charge reports generated in accordance with this part of ISO 17575 are consistent with the requirements derived from the architectural concept defined in ISO 17573:2010. The definitions in ISO 17575-1:2016 comprise - reporting data, i.e. data for transferring road usage data from Front End to Back End, including a response from the Back End towards the Front End, - data for supporting security mechanisms, - contract data, i.e. data for identifying contractually essential entities, - road usage data, i.e. data for reporting the amount of road usage, - account data for managing a payment account, - versioning data, and - compliance checking data, i.e. data imported from ISO 12813:2015, which are required in compliance checking communication. Annex A contains the data type specifications using ASN.1 notation. The protocol implementation conformity statements (PICS) proforma are provided in Annex B. Annex C provides a graphical presentation of the structure of the data elements described in Clause 7. Annex D provides information on how this part of ISO 17575 can be used in EETS environment and how the requirements that are specified in the EU-Decision 2009/750 are addressed by this standard.
