Intelligent transport systems — Traffic and travel information (TTI) via transport protocol experts group, generation 2 (TPEG2) — Part 18: Traffic flow and prediction application (TPEG2-TFP)
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. Generally, TFP focuses on the following requirements: — provides dynamic navigation systems with up-to-date traffic state information; — ensures travel safety for the driver; — enables the calculation of alternative routes; — avoids delays (e.g. traffic jams); — lowers traffic load on over-saturated parts of the network; — keeps the driver informed about current and upcoming traffic; — compact and efficient coding of the traffic information.

Introduction
History
TPEG technology was originally proposed by the European Broadcasting Union (EBU) Broadcast
Management Committee, who established the B/TPEG project group in the autumn of 1997 with a brief
to develop, as soon as possible, a new protocol for broadcasting traffic and travel-related information
in the multimedia environment. TPEG technology, its applications and service features were designed
to enable travel-related messages to be coded, decoded, filtered and understood by humans (visually
and/or audibly in the user’s language) and by agent systems. Originally, a byte-oriented data stream
format, which may be carried on almost any digital bearer with an appropriate adaptation layer,
was developed. Hierarchically structured TPEG messages from service providers to end-users were
designed to transfer information from the service provider database to an end-user’s equipment.
