ISO/TS 21219-23:2016描述了新的移动服务，如汽车共享、汽车租赁或停车换乘，以及通过多式联运或非车载导航整合不同的运输模式，正变得越来越重要。此外，交通基础设施的合作管理需要提供从中央知识库到旅行者移动设备的专用路线的精确信息和指导。 此类用例由本文档中定义的TPEG应用程序解决。 道路和多式联运路线（RMR）应用程序可以为道路路线和多式联运路线提供服务，包括多种运输模式和停车场。例如，最佳多式联运路线可能包括一辆汽车到一个有停车设施的火车站，一辆火车连接到目的地附近的一个车站，以及从火车站到旅客目的地的当地公共交通设施。 通过TPEG技术，路由信息的标准化交付对RMR TPEG服务的用户有一些潜在的好处，例如: -启用特殊的路由服务，如风景路由或生态路由； -充分利用整个交通网络，即不仅仅是道路网络； -为旅行者节省成本和时间； -协调车内导航和交通管理，例如通过可变信息标志提供路线建议； -个性化服务供应，即考虑用户特定特征的信息服务。 上面的一些用例，尤其是个性化服务，可能需要对等方- 对等（P2P）通信，而其他人可能采用广播通信方法，例如城市路由。

ISO/TS 21219-23: 2016 describes new mobility services like car sharing, car rental or park and ride as well as the integration of different transport modes by multimodal or off-board navigation are gaining increasing importance. Furthermore, the cooperative management of the transport infrastructure requires the provision of precise information and guidance on dedicated routes from a central knowledge base to a traveller's mobile device. Such use cases are addressed by the TPEG application defined in this document. The Road and Multimodal Routes (RMR) application enables the service provision for road routes as well as multimodal routes including more than one transport mode and parking. For example, an optimal multimodal route may include a drive by car to a train station with parking facility, a train connection to a station nearby the destination and a local public transport ride from the train station to the traveller's destination. The standardized delivery, via TPEG technology, of routing information has some potential benefits for the users of an RMR TPEG service, for instance: - Enabling of specialized routing services like scenic routing or Eco routing; - The best use of the overall transport network, i.e. not only the road network; - Cost and time savings to traveller; - Harmonization of in-car navigation and traffic management, e.g. routing advices by variable message signs; - Personalized service provisioning, i.e. information services considering the specific characteristics of a user. Some of the use cases above, in particular personalized service, may require a Peer-to-Peer (P2P) communication while others may apply a broadcast communication approach, e.g. city routing.
