标准范围

可变信息标志（VMS）安装在交通管理人员发现经常需要向出行的公众传达信息的区域，例如立交桥上游，以及时提醒公众下游拥堵，以便他们改变路线。这使得交通管理人员能够提高旅客出行的效率、安全性和质量。为了管理虚拟机的操作和显示的消息，需要在管理系统和虚拟机之间进行信息交换。本文件确定了用户对发光二极管（LED）矩阵虚拟机管理的基本需求，并将这些需求追溯到可互操作的设计。这包括识别设备、其功能和状态的能力。注？1？本文件类似于NTCIP 1203 v03的部分内容，它定义了如何使用旧版本的SNMP管理虚拟机，是本文件中的规范性参考。注2:ISO 20684-1提供了关于本系列标准与ITS体系结构整体关系的更多细节。

Variable message signs (VMSs) are installed in areas where traffic managers identify a frequent need to convey information to the travelling public, such as upstream from interchanges to alert the public to downstream congestion in time for them to alter their routes. This allows traffic managers to improve the efficiency, safety, and quality of traveller journeys.In order to manage the operation of a VMS and the messages displayed, information exchange between the management systems and the VMS is needed.This document identifies basic user needs for the management of light-emitting diode (LED) matrix VMSs and traces these needs to interoperable designs. This includes the ability to identify the device, its capabilities, and its status.NOTE 1   This document is similar to portions of NTCIP 1203 v03, which defines how to manage VMSs using an older version of SNMP and is a normative reference in this document.NOTE 2   ISO 20684-1 provides additional details about how this series of standards relates to the overall ITS architecture.
