ISO/TS 24530-4:2006-Traffic and Travel Information (TTI) — TTI via Transport Protocol Experts Group(TPEG) Extensible Markup Language(XML) — Part 4: tpeg-ptiML
This document establishes the XML encoding of the method of the Public Transport Information application.
The Public Transport Information Application is intended to cover all modes of public (ie collective) transport as well as inter-urban and intra-urban travel. The application itself is designed to allow the efficient and language independent transmission of public transport information either directly to an end-user, be it the public or another service provider, such as broadcasters, service operators or other information disseminating points or centres for onward transmission.
It is important to bear in mind that these "views” are merely presentational aides; they have little to do with the content in the individual data elements. They do, however, indicate how data elements must be grouped if a presentation in any of these views is intended. Unlike the TPEG-RTM application, TPEG-PTI benefits from the nodal structure of public transport, making use of its discrete start, end and stopping points as well as being limited to fixed, be it real or virtual, routes.
It is vital, for further understanding of this document, to have more than a passing understanding of the TPEG-PTI Binary specification which describes, among other things, in a step-by step approach: Message Management, Report views and how they are structured hierarchically to provide a full Public Transport Information message together with the TPEG Location Referencing system.
