标准摘要
[中文适用范围]： 本标准规定了智能运输系统路边模块AP-DATEX数据接口的第一部分的概述，包括ITS服务、数据交换要求、对话机制以及安全建议等内容 [外文原描述]： Field devices are a key component in intelligent transport systems (ITS). Field devices include traffic signals, message signs, weather stations, traffic sensors, roadside equipment for connected ITS (C-ITS) environments, etc. Field devices often need to exchange information with other external entities. Field devices can be quite complex, necessitating the standardization of many data concepts for exchange. As such, the ISO 22741 series is divided into several individual Parts. This document (Part 1) introduces the ISO 22741 series and provides normative content that applies to the rest of the series.
