本文件构成CEN 16157 DATEX II系列标准和技术规范的一部分。本系列指定并定义了支持交通和旅行领域数据和信息交换和共享使用的组件方面。组件方面包括用于交换的框架和上下文、建模方法、数据内容、数据结构和关系以及通信规范。本文件第9部分规定了适用于城市环境中交通信号管理应用的附加数据模型结构。本部分规定了数据概念，以支持以与现有C-ITS标准和技术规范一致的方式交换交通信号状态信息、交叉口几何定义和属性。它为以下参与者的任意两个实例之间的数据交换建立规范:-交通信息中心，-交通管制中心（TCC），-服务提供商（SP）。本文件的使用可能适用于其他参与者。

This document constitutes a part of the CEN 16157 DATEX II series of standards and technical specifications. This series specifies and defines component facets supporting the exchange and shared use of data and information in the field of traffic and travel. The component facets include the framework and context for exchanges, the modelling approach, the data content, the data structure and relationships and the communications specification. Part 9, this document, specifies additional data model structures that are applicable for traffic signal management applications in the urban environment. This part specifies data concepts to support the exchange of traffic signal status messaging, intersection geometry definition and attribution in a consistent way with existing C-ITS standards and technical specifications. It establishes specifications for data exchange between any two instances of the following actors: - Traffic Information Centres (TICs), - Traffic Control Centres (TCCs), - Service Providers (SPs). Use of this document may be applicable for use by other actors.
