本文件规定了TPEG应用流量和预测（TFP）。它被专门设计为使用不同的渠道向各种接收器提供信息，首先包括数字广播和互联网技术。交通流和预测信息用于车内应用，也可以通过文本、语音和图形输出设备直接呈现给用户。 TFP以状态为导向，即传输的信息不断更新接收器对专用道路网络的知识。特别是，即使没有异常交通状况，交通状态也会在任何时间、网络的所有路段上进行传递。 交叉引用:ISO 17572-3ISO 21219-5ISO 17572-2ISO 21219-6ISO/TS 24530（系列）ISO/TS 21219-9ISO 21219-2ISO 21219-3ISO/TS 18234（系列）ISO/IEC 19501:2005ISO/TS 21219-21ISO/TS 21219-1ISO/TS 21219-22ISO 21219-4ISO/TS 21219-15ISO/TS 21219-7购买本文件时可提供的所有现行修订。

This document specifies the TPEG application Traffic Flow and Prediction (TFP). It has been specifically designed to provide information to a variety of receivers using different channels, including in the first instance digital broadcasting and Internet technologies. Traffic flow and prediction messages are intended for in-car applications and can also be presented directly to the user by textual, voice and graphical output devices. TFP is status oriented, i.e. the transmitted information continuously updates the receiver's knowledge for a dedicated road network. In particular the traffic states are delivered any time and for all road sections of the network, even when there are no abnormal traffic situations.Cross References:ISO 17572-3ISO 21219-5ISO 17572-2ISO 21219-6ISO/TS 24530 (series)ISO/TS 21219-9ISO 21219-2ISO 21219-3ISO/TS 18234 (series)ISO/IEC 19501:2005ISO/TS 21219-21ISO/TS 21219-1ISO/TS 21219-22ISO 21219-4ISO/TS 21219-15ISO/TS 21219-7All current amendments available at time of purchase are included with the purchase of this document.
