适用范围：This document establishes the method of delivering Road Traffic Messages within a TPEG service. TheTPEG-RTM application is designed to allow the efficient and language independent delivery of roadinformation directly from service provider to end-users. The information provided relates to event and somestatus information on the road network and on associated infrastructure affecting a road journey. For example,limited information about abnormal operation of links in the network may be included, such as ferries, liftingbridges,etc.The term “application” is used in TPEG specifications to describe specific applications, such as in this casethe Road Traffic Message application, which comprises three information containers: the MessageManagement Container, the Application Event Container and the TPEG-Location Container. The first twoContainers are fully described herein and the TPEG-Location Container is described in CEN ISO/TS 18234-6.Each TPEG application (e.g. TPEG-RTM) is assigned a unique number that is called the applicationidentification (AID). An AID is defined whenever a new application is developed. The AID is used within theTPEG-Service and Network Information Application (CEN ISO/TS 18234-3) to indicate how to process TPEGcontent and allows routing of data to an appropriate application decoder.AID = 0001 is assigned to the TPEG-Road Traffic Message application, described in this specification.A hierarchical methodology has been developed to allow the creation of messages from a set of TPEG-RTMtables, which are essentially word oriented and cover most needs. Many of the TTI descriptive words, in theTPEG-RTM tables, were obtained from the DATEX dictionary (ENV 13106), which embodies European TTIknowledge of the last ten years or more, including a deconstruct of the phrase oriented RDS-TMC events list(EN ISO 14819-2). These TPEG-RTM tables (essentially word oriented data object dictionaries) comprise awide ranging ability to describe a TTI event and some status information, introducing new precision in anumber of areas such as “vehicle types”, “positional information on the carriageway” and “diversion routingadvice”.NOTE Explicit backwards compatibility with the RDS-TMC events list (EN ISO 14819-2) could not be achieved sincesome “update classes”, such as “29 Reference to Audio Broadcasts” and “30 Service Messages”, fall outside theTPEG-RTM remit.
