Establishes the top-level "containers" for TPEG messages in XML and the common data types that are used by tpegML applications (e.g. tpeg-ptiML).

This document establishes the top-level “containers” for TPEG messages in XML and the common data types that are used by tpegML applications (e.g. tpeg-ptiML). Inherently tpegML is designed to “map” TPEG Binary (ISO/TS 18234 series), however additional tags are provided to create a message and message set structure to facilitate internet file delivery.

The TPEG applications are intended to convey information to end-users. The information provided relates to event and status information on transport networks and on associated infrastructure affecting a journey. For example, limited information about abnormal operation of links in the network may be included, such as ferries, lifting-bridges, etc.

The TPEG applications have the broad objective to allow the generation of Traffic and Travel Information (TTI) messages, for delivery to the end-user by one or more bearers. A hierarchical methodology has been developed to allow the creation of messages from a set of TPEG tables, which are essentially word-oriented and cover most needs.

These TPEG tables (essentially word-oriented data object dictionaries) comprise a wide ranging ability to describe a TTI event and some status information, introducing new precision in a number of areas such as “Vehicle types”, “Positional information on the carriageway” and “Diversion routing advice”.

It is vital, for further understanding of this document, to have more than a passing understanding of the TPEG binary specifications which describe, among other things, in a step-by step approach: Message Management, Level One Classes and how they are structured hierarchically to provide a full message/information application message together with the TPEG Location Referencing system.
