Overview
EN 12896-2:2026 – Public transport - Reference data model - Part 2: Public transport network is a draft European Standard developed by CEN/TC 278. As part of the Transmodel series, this standard defines a reference data model for describing and managing public transport networks. Its primary aim is to support harmonized, interoperable, and consistent public transport data management, facilitating network planning, service interfaces, and seamless journey planning across Europe.
The standard covers key data packages essential to building a complete conceptual model of public transport networks:
- Network Description
- Fixed Objects
- Tactical Planning Components
- Explicit Frames
EN 12896-2:2026 supports modular adoption and practical mapping to software implementations, especially for interoperability across different domains within the public transport sector.
Key Topics
-
Network Description Model
Captures the physical elements of the public transport infrastructure, including various points (e.g., stops, junctions) and links (e.g., road, rail, or wire elements). Establishes a clear structure for layers of network topology and their relationships.
-
Fixed Object Model
Describes fixed geographical entities such as stopping locations, points of interest, and their associated facilities (like equipment and navigation paths). Helps ensure comprehensive mapping of accessible places and transfer points within the public network.
-
Tactical Planning Components
Provides a framework for modeling work patterns of vehicles, such as journey patterns, timing, service patterns, and constraints. This supports detailed operational planning and scheduling.
-
Network Restrictions
Defines operational constraints arising from the network's physical features (e.g., overtaking possibilities, vehicle-type allowances, and restrictions specific to infrastructure points or links). This forms a basis for realistic service planning within operational and infrastructural limitations.
-
Explicit Frames
Offers mechanisms to define data sets tailored for specific use cases, helping public transport operators standardize their data exchanges and maintain version consistency.
Applications
-
Transport Network Planning and Design
Enables city authorities, operators, and planners to model, analyze, and optimize public transport routes based on a standardized conceptual framework. Supports integration of flexible and regular services and aids in long-term infrastructure investments.
-
System Integration and Interoperability
Facilitates the development and deployment of interoperable IT solutions for public transportation, including journey planning systems, network management platforms, and real-time information systems.
-
Passenger Information and Accessibility
Provides robust data structures to support accessible transport information, journey planning for passengers with mobility impairments, and clear navigation routes at stops and stations.
-
Data Exchange and Compliance
Supports seamless data sharing across national and European borders, ensuring public transport operators comply with the latest standards for data consistency and system compatibility.
