ISO 17438-1:2016规定了室内导航系统体系结构，包括添加到现有ITS系统中的附加组件，以及为各类用户（包括使用个人和车辆ITS站的驾驶员、乘客和行人）提供室内导航的用例。 -个人车辆及其站点作为最终用户终端运行室内导航功能。 -包含室内几何结构、网络拓扑和反映室内空间特征的POI数据的室内地图。 -包含定位基础设施信息的室内定位参考数据:WiFi AP、RFID阅读器、蓝牙AP等。 -数据提供商提供室内地图或室内定位参考数据。 -室内数据服务器注册表，用于提供室内数据服务器的信息。 -使用室内定位参考数据，个人车辆及其站点中的室内定位功能。 -使用室内定位参考数据在中央ITS站实现室内定位功能。 -P/V ITS站和中央ITS站之间的接口，用于传输室内地图数据和室内定位参考数据。 ISO 17438-1:2016包括“一般信息”，它提供了ISO 17438各部分的一般概述和结构。它还规定了与个人和车辆及其站点的室内导航相关的“用例”。

ISO 17438-1:2016 specifies the indoor navigation system architecture including additional components that are added to the existing ITS system and use cases in providing indoor navigation to various types of users including drivers, passengers, and pedestrians using personal and vehicle ITS stations. - The personal and vehicle ITS station in the role of end user terminal running indoor navigation functionality. - Indoor map containing indoor geometry, network topology, and POI data reflecting characteristics of indoor space. - Indoor positioning reference data containing information of positioning infrastructure: WiFi AP, RFID Reader, Bluetooth AP, etc. - Data providers to provision the indoor map or indoor positioning reference data. - Indoor data server registry to provision the information of indoor data server. - Indoor positioning functionality in the personal and vehicle ITS station using indoor positioning reference data. - Indoor positioning functionality in the central ITS station using indoor positioning reference data. - Interface between the P/V ITS station and central ITS station to communicate indoor map data and indoor positioning reference data. ISO 17438-1:2016 includes "General Information", which provides a general overview and structure of each part of ISO 17438. It also specifies "Use Cases" related to the indoor navigation for personal and vehicle ITS stations.
