标准摘要
[中文适用范围]： 本国际标准规定了车载导航系统使用的消息内容和格式。 它的重点是生成或增强路由指令所需的消息。 特别关注不一定包含在更一般的流量管理消息列表中的消息。 尽管该国际标准强调了对利用车载地图数据库的本地确定路线引导（LDRG）系统的要求，但它还包括主要由集中确定路线引导（CDRG）系统使用的消息和某些增值消息。 [外文原描述]： ISO 15075:2003 specifies message content and format utilized by in-vehicle navigation systems. Its emphasis is on messages that are required to generate or enhance routing instructions. There is a particular focus on messages that would not necessarily be included in a more general traffic management message list. Although ISO 15075:2003 emphasizes requirements for Locally Determined Route Guidance (LDRG) systems that utilize on-vehicle map databases, it also includes messages that would be utilized primarily by Centrally Determined Route Guidance (CDRG) systems and certain value-added messages.
