Overview
CEN/TS 16157-8:2026 is a technical specification developed by CEN (European Committee for Standardization) as part of the DATEX II family of standards for intelligent transport systems. This crucial part - Part 8 - defines additional data model structures specifically tailored for traffic management applications in urban environments. It establishes enhanced data specifications that facilitate the exchange of traffic management plans, rerouting information, and specialized urban extensions, building on the DATEX II core model.
The standard is instrumental in supporting seamless interoperability and efficient communication between key actors such as Traffic Control Centres (TCCs), Traffic Information Centres (TICs), and Service Providers (SPs). By addressing the complex requirements of urban mobility, CEN/TS 16157-8:2026 aids cities and operators in improving traffic flow, network resilience, and traveler information services consistent with the European Sustainable and Smart Mobility Strategy.
Key Topics
- Urban Extensions to DATEX II: Adds specific classes and enumerations targeting urban traffic scenarios, infrastructure, and road user types.
- Traffic Management Plans: Defines structured ways to design, store, and activate coordinated action sets to minimize disruption and optimize urban road networks.
- Rerouting Management Enhancements: Introduces refined models for rerouting strategies, route allocation, and capacity management-vital for congested urban areas and incident response.
- Support for Non-Motorized Road Users: Expands data models to recognize cyclists, pedestrians, and other non-vehicular users, enhancing inclusivity and safety.
- Work Coordination and Workflow: Supports real-time information exchange for the activation, update, and termination of traffic management measures across cooperating organizations.
Applications
CEN/TS 16157-8:2026 greatly extends the practical value of DATEX II for a wide variety of stakeholders involved in urban mobility and smart city operations, including:
- Traffic Control and Information Centres: Enables standardized, real-time coordination of network management actions, especially where multiple stakeholders and systems must operate integrally.
- Service Providers: Ensures compatibility in delivering detailed, reliable traffic and rerouting information to end-users via navigation apps or public displays.
- Urban Mobility Planners: Allows for detailed modeling and management of diverse urban infrastructure-including lanes, crossings, and specialized vehicle types-supporting scenario testing and future-ready planning.
- Incident and Event Management: Facilitates rapid deployment and communication of rerouting and traffic regulation orders during disruptions, emergencies, or planned events.
- Integration with Smart City Platforms: Supports broader IoT and ITS ecosystems as part of a city’s digital strategy, strengthening multimodal management, and open-data initiatives.
Related Standards
CEN/TS 16157-8:2026 is closely integrated with several other key standards in the DATEX II series, including:
- EN 16157-1:2018: Context and framework for DATEX II.
- EN 16157-2:2019: Location referencing underpinning precise geographic communication.
- EN 16157-3:2019: Situation publication, offering foundational models for traffic events and management.
- EN 16157-7:2018: Common data elements standardizing shared components used throughout DATEX II.
- CEN/TS 16157-9: Map data publication for integration with digital map representations.
By leveraging CEN/TS 16157-8:2026, cities and mobility providers can ensure compliance, foster open data exchange, and realize intelligent, interoperable, and sustainable urban transport management. The standard is essential for aligning local and trans-European transport initiatives and enhancing the overall traveler experience.
