ISO TS 18234-4:2006确立了在TPEG服务中传递道路交通信息的方法。TPEG-RTM应用程序旨在让道路信息能够从服务提供商直接高效、独立于语言地传递给最终用户。所提供的信息与事件和一些状态信息有关，这些信息涉及道路网络和影响道路行程的相关基础设施。例如，可以包括关于网络中链路的异常操作的有限信息，例如渡轮、吊桥等。

ISO TS 18234-4:2006 establishes the method of delivering Road Traffic Messages within a TPEG service. The TPEG-RTM application is designed to allow the efficient and language independent delivery of road information directly from service provider to end-users. The information provided relates to event and some status 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, lifting-bridges, etc.
