电子收费

[中文适用范围]： 本文件建立了用于增强自主电子收费 (EFC) 系统中定位的短距离通信要求。定位增强用于向车载设备 (OBE) 告知地理位置和收费对象的标识。本文件规定了位置和航向信息的提供以及防止使用虚假 RSE 操纵 OBE 的安全手段。定位增强通信 (LAC) 发生在车辆中的 OBE 和固定 RSE 之间。本文件适用于自主操作模式下的 OBE。本文件通过使用 DSRC 第 7 层提供的专用短距离通信 (DSRC) 通信服务指定了用于定位增强的属性和功能，并使这些 LAC 属性和功能可供 RSE 和 OBE 上的 LAC 应用程序使用。属性和功能在应用程序数据单元 (ADU；参见图 1) 级别指定。如图 1 所示，本文件适用于： — OBE 和 RSE 之间的应用程序接口定义； — DSRC 应用层接口，如 ISO 15628 和 EN 12834 所规定； — DSRC 堆栈的使用。LAC 适用于多种短距离通信媒体。本文件提供了有关 EN 15509 所规定的 CEN-DSRC 堆栈的具体定义。附件 C、D、E 和 H 规定了 ETSI/ES 200 674-1[9]、ISO CALM IR[3]、ARIB DSRC[10] 和 WAVE DSRC[11] 所规定的意大利 DSRC 的使用。本文件的附件 B 中包含协议实施一致性声明 (PICS) 形式，附件 F 中包含事务示例。附件 G 重点介绍了如何将本文件用于欧洲电子收费服务 (EETS)。测试规范不属于本文件的讨论范围。关键 AP 申请流程 ADU 应用数据单元 LAC 定位增强通信 OBE 车载设备 RSE 路边设备 图 1 — LAC 应用界面 [外文原描述]： This document establishes requirements for short-range communication for the purposes of augmenting the localization in autonomous electronic fee collection (EFC) systems. Localization augmentation serves to inform on-board equipment (OBE) about geographical location and the identification of a charge object. This document specifies the provision of location and heading information and security means to protect against the manipulation of the OBE with false RSE. The localization augmentation communication (LAC) takes place between an OBE in a vehicle and fixed RSE. This document is applicable to OBE in an autonomous mode of operation. This document specifies attributes and functions for the purpose of localization augmentation, by making use of the dedicated short-range communications (DSRC) communication services provided by DSRC Layer 7, and makes these LAC attributes and functions available to the LAC applications at the RSE and the OBE. Attributes and functions are specified on the level of application data units (ADUs; see Figure 1). As depicted in Figure 1, this document is applicable to: — the application interface definition between OBE and RSE; — the interface to the DSRC application layer, as specified in ISO 15628 and EN 12834; — the use of the DSRC stack. The LAC is suitable for a range of short-range communication media. This document provides specific definitions regarding the CEN-DSRC stack as specified in EN 15509. Annexes C, D, E and H provide for the use of the Italian DSRC as specified in ETSI/ES 200 674-1, ISO CALM IR ARIB DSRC and WAVE DSRC. This document contains a protocol implementation conformance statement (PICS) proforma in Annex B and transaction examples in Annex F. Annex G highlights how to use this document for the European Electronic Toll Service (EETS). Test specifications are not within the scope of this document.
