本文档定义了电子收费（EFC）领域的语法和语义。根据ISO/IEC 8824 1中规定的抽象语法符号1（ASN.1）技术提供数据类型和值的分配。本文件特别规定: -ASN.1（EFC和道路用户收费领域内的数据）类型； -ASN.1（数据）一种更通用的类型，在与EFC相关的标准中更具体地使用。 本文件不试图定义ASN.1（数据）类型，这些类型主要与与EFC相关的其他领域有关，如合作智能交通系统（C-ITS）、金融部门等。

This document specifies the syntax and semantics of data objects in the field of electronic fee collection (EFC). The definitions of data types and assignment of values are provided in accordance with the abstract syntax notation one (ASN.1) technique, as specified in ISO/IEC 8824‑1. This document defines: —    ASN.1 (data) types within the fields of EFC; —    ASN.1 (data) types of a more general use that are used more specifically in standards related to EFC. This document does not seek to define ASN.1 (data) types that are primarily related to other fields that operate in conjunction with EFC, such as cooperative intelligent transport systems (C-ITS), the financial sector, etc.
