智能交通系统

[中文适用范围]： 本文件提供了通过应用地理围栏管理受控区域 (CZ) 道路交通的信息和规范。具体而言，本文件规定了用于管理受控区域的“受控区域数据字典”(CZDD)，并提供了一个可扩展的工具包，监管机构可以使用该工具包，例如，向潜在的 CZ 用户（例如车辆）告知以下内容： — CZ 区域，即 CZ 的地理边界； — CZ 访问条件（包括豁免）； — 指示这些 CZ 访问条件何时适用的时间窗口。这允许潜在的 CZ 用户通过预先规划或临时重新规划来选择合适的路线。本文件还提供了如何使用该工具包的说明和指南。该工具包是根据 ISO 21217 中规定的通用 ITS 站和通信架构以及可选适用的 C-ITS 协议和程序设计的，例如关于“服务公告”的 ISO 22418、关于“本地动态地图”的 ISO 18750 和关于全球唯一标识符的 ISO 17419。可以通过符合 ISO 21177 来提供网络安全规定。执行超出了本文档的范围。 [外文原描述]： This document provides information and specifications on the management of road traffic in controlled zones (CZ) through the application of geofencing. Specifically, this document specifies a “Controlled Zone Data Dictionary” (CZDD) for management of controlled zones, and provides an extendible toolkit that regulators can use, for example, to inform potential CZ users (e.g. vehicles) about: — the CZ area, i.e. the geographical boundaries of the CZ; — CZ access conditions including exemptions; — time windows indicating when these CZ access conditions are applicable. This allows potential CZ users to select an appropriate routing, either by pre-trip planning or ad hoc re-routing. This document also provides illustrations and guidelines on how to use this toolkit. The toolkit is designed in accordance with the general ITS station and communications architecture specified in ISO 21217, and with optionally applicable C-ITS protocols and procedures, e.g. ISO 22418 on “Service Announcement”, ISO 18750 on the “Local Dynamic Map”, and ISO 17419 on globally unique identifiers. Cybersecurity provision can be provided through conformance to ISO 21177. Enforcement is out of scope of this document.
