ISO 14819-1:20 03规定了无线电数据系统的编码协议-交通消息信道(RDS-TMC)-RDS-TMC使用ALERT-C协议,该协议被设计成主要提供面向事件的道路驾驶员信息消息。
为未来的开发留下了许多“钩子”,并且确实包括了一些面向状态的道路驾驶员信息消息。该协议旨在与ALERT-Plus协议紧密相连,ALERT-Plus协议是专门为面向状态的道路驾驶员信息而设计的;这两种协议可以在同一RDS传输中可用。
ENV 12313-4中规定了ALERT-Plus协议。
ISO 14819-1:2003 specifies the coding protocol for Radio Data System - Traffic Message Channel (RDS-TMC) - RDS-TMC using the ALERT-C protocol that is designed to provide mostly event-orientated road driver information messages.
Many "hooks" have been left for future development and indeed a few status-orientated road driver information messages were included. This protocol is designed to be closely linked to the ALERT-Plus protocol, which is specifically designed for status-orientated road driver information; both protocols may be available in the same RDS transmission.
The ALERT-Plus protocol is specified in ENV 12313-4.
