Overview

ISO/TS 21219-23:2016 - TPEG2-RMR (Intelligent transport systems - Traffic and travel information via TPEG2 - Part 23: Roads and multimodal routes) defines the Roads and Multimodal Routes (RMR) application for TPEG Generation 2. It standardizes the representation and delivery of routing and multimodal trip information (including parking, car sharing, car rental and park-and-ride) from a central knowledge base to traveller devices. The specification supports both broadcast and Peer-to-Peer (P2P) communication models and provides machine-readable message structures to enable off-board navigation, cooperative infrastructure management and personalized routing services.

Key topics and requirements

• Message structure and components: standardized elements such as Route, RouteSegment, Parking, SegmentLocation, PointLocation and travel detail components (RoadTravelDetails, PTTravelDetails, PedestrianTravelDetails).
• Session and request messages: RMR request/response message models (e.g., RMRRequestMessage, RMRRouteReqParams, Activate/Terminate session parameters).
• Data types and tables: datatypes (WGS84Coordinate, EnergyConsumption, Operator) and lookup tables (RouteType, ModeType, ParkType, RouteObjectives, ErrorCode).
• Application constraints: application identification, version signalling, ordered components, extendibility and TPEG Service Component framing rules.
• Communication scenarios: support for broadcast (e.g., city routing) and P2P (for personalized routing) delivery.
• Physical representations: normative annexes defining TPEG-Binary and TPEG-ML (XML) representations for interoperability.
• Location referencing: integration with TPEG2 location referencing to support map-based and human-readable outputs.

Practical applications

• Multimodal trip planning that combines car, rail, transit and walking with parking recommendations (e.g., drive-to-station + park + train + local transit).
• Specialized routing services like eco routing and scenic routing.
• Real-time guidance for cooperative traffic management and harmonized in-vehicle navigation (including routing advice from variable message signs).
• Integration of shared mobility services (car sharing, rental) and parking availability into navigation apps.
• Personalized routing delivered via P2P to accommodate user preferences, vehicle type or energy consumption constraints.

Who uses this standard

• ITS service providers and content aggregators
• Navigation system manufacturers and in-car infotainment vendors
• Traffic Management Centers and municipal authorities
• Mobility-as-a-Service (MaaS) and multimodal trip planner developers
• Automotive OEMs and telematics platform providers

• ISO/TS 21219 series (TPEG Generation 2 core rules and toolkit)
• ISO/TS 21219-6 (Message Management) and ISO/TS 21219-7 (Location Referencing)
