ISO 21219-16:2023

Overview

ISO 21219-16:2023 specifies the TPEG2 Fuel Price Information and Availability application (TPEG2‑FPI), part of the ISO 21219 series for Intelligent Transport Systems (ITS). TPEG2‑FPI standardizes delivery of fuel station data - location, fuel types, pricing and availability - using TPEG (Transport Protocol Experts Group) generation 2 messaging. Published as an International Standard in 2023 (first edition), it replaces the earlier Technical Specification and expands fuel-kind support for evolving markets.

Key SEO phrases: ISO 21219-16, TPEG2, fuel price information, fuel availability, intelligent transport systems, TPEG FPI.

Key technical topics and requirements

• FPI structure and message design: Defines the overall FPI message architecture, including factoring out reusable definitions and support for large numbers of stations with modest bandwidth.
• Message components and datatypes: Specifies components such as FuelingDefinitions, StationFuelingInformation, StationExtraInformation, StationSiteInfo and location clusters (map, POI, navigation-along-road) plus associated datatypes (fuel types, prices, contact info, coordinate formats).
• Application lifecycle controls: Application identification, version number signalling, ordered components, and extension mechanisms to ensure interoperability and graceful evolution.
• Transmission models: Guidance for transmission of tables and use of MMC (Message Management Container) for message combinations and large datasets.
• Normative encodings: Includes normative representations for TPEG binary and TPEG‑ML (see Annex A and B) to ensure consistent encoding/decoding across systems.
• Reference tables: Predefined FPI tables (e.g., FuelKindType, PaymentMethodType, FuelBrand) standardize values and semantics across implementations.

Practical applications

• Navigation and in‑vehicle systems: Integrate live fuel prices and availability into route planning and POI displays, enabling drivers to find cost‑effective refuelling stops.
• Fleet management and telematics: Optimize refuelling strategies and reduce operational costs by incorporating standardized fuel price feeds into fleet planning tools.
• Traffic and travel service providers: Add FPI as an add‑on service alongside traffic information to enrich travel information services.
• Fuel retailers and aggregators: Distribute standardized price and availability data to third‑party services and navigation apps.
• Road authorities and safety services: Improve safety and reduce instances of vehicles running out of fuel by conveying availability information.

Who should use this standard

• ITS developers, navigation system OEMs, telematics vendors and app developers
• Traffic and travel information providers and broadcasters
• Fleet operators, fuel price aggregators and fuel station operators
• Standards implementers and national ITS authorities

Related standards

• ISO 21219 series (TPEG2 applications)
• For electric vehicle charging information, use TPEG2‑EMI (ISO/TS 21219‑25) - TPEG2‑FPI is not intended as the primary solution for EV charging infrastructure data.

This standard supports interoperable, bandwidth‑efficient distribution of fuel pricing and availability across the ITS ecosystem, helping reduce costs, emissions and refuelling uncertainty for drivers and fleets.
