本文档规定了电子收费（EFC）领域数据对象的语法和语义。数据类型的定义和语义的分配是根据ISO/IEC 8824-1中规定的抽象语法符号一（ASN.1）技术提供的。本文件定义了: --EFC字段内的ASN.1（数据）类型； --ASN.1（数据）类型具有更广泛的用途，在与EFC相关的标准中更具体地使用。 本文档并不试图定义主要与与EFC协同工作的其他领域相关的ASN.1（数据）类型，例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 semantics 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 field 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.
