Unlocking Turbocharged Productivity in Public Transport: A Guide to Key IT Standards

Managing modern public transport systems isn’t just about running trains and buses—today, it’s about harnessing technology to deliver efficiency, seamless data exchange, robust security, and scalable, integrated services. In this article, we explore three pivotal international standards for IT applications in transport:

• CEN/TS 16614-1:2026 (NeTEx Part 1): Public Transport Network Topology Exchange
• CEN/TS 16614-2:2026 (NeTEx Part 2): Scheduled Timetables Exchange
• ISO/TS 24854-5:2026: ITS Facilities Layer Message Sets

These standards underpin everything from real-time passenger information to automated vehicle management and data-driven service optimization. For businesses in the transport sector, implementing these frameworks isn’t just about compliance—it’s about unlocking productivity, enhancing security, and enabling seamless scaling in an increasingly interconnected world.

Overview / Introduction

The global transport sector is undergoing profound digital transformation. Information technology (IT) applications are central to this, optimizing how networks operate and how data flows between systems, vehicles, and stakeholders. International standards play a vital role—they ensure that data exchanged between operators, authorities, and supporting IT systems is consistent, secure, and interoperable.

In this article, we demystify three crucial standards:

1. CEN/TS 16614-1:2026 (NeTEx Part 1): Focuses on exchanging digital representations of public transport networks, capturing detailed topology, connectivity, and layout.
2. CEN/TS 16614-2:2026 (NeTEx Part 2): Standardizes the exchange of scheduled timetables, ensuring all journey, timing, and scheduling data is accurately communicated.
3. ISO/TS 24854-5:2026: Defines intelligent transport systems message sets, enabling structured, flexible, and efficient message exchange at the facilities layer.

Regardless of your role—public transport operator, IT architect, regulator, or service provider—understanding and adopting these standards delivers measurable business advantages, from improving reliability and passenger information accuracy to facilitating easier scaling of digital services across regions.

CEN/TS 16614-1:2026 – Public Transport Network Topology Exchange (NeTEx Part 1)

Full Title: Public transport - Network and Timetable Exchange (NeTEx) - Part 1: Public transport network topology exchange format

Scope and Purpose

CEN/TS 16614-1:2026 is the foundation of the NeTEx (Network and Timetable Exchange) family. It defines how public transport network topology is exchanged in an open, modular, and extensible way. This means creating universally understood models for the physical and operational layout of transport networks—including stops, routes, lines, transfer points, and network layers.

The 2026 revision introduces powerful new enhancements aligned with the wider Transmodel (EN 12896) revision, ensuring full compatibility and consistent semantics across platforms. These updates include digital representations for vehicle layouts (deck plans, accessibility features), more granular compound vehicle compositions (like train sets), and quality improvements to address industry feedback and regulatory developments such as the EU Delegated Regulation 2017/1926.

Key Requirements and Specifications

• Comprehensive Data Schema: Utilizes XML and model-driven design, allowing both conceptual and machine-readable mappings for seamless system integration.
• Extensibility: Modularization allows organizations to implement only the aspects relevant to their operations, minimizing complexity while maximizing flexibility.
• Interoperability: Designed to be consistent with other core standards, including Transmodel and SIRI (Service Interface for Real-time Information), and harmonizes with existing national frameworks (TransXChange, VDV 452, Neptune, etc.).

Who Needs to Comply?

• Public Transport Authorities (PTAs)
• Transport Operators (bus, rail, metro, tram, ferry, etc.)
• IT System Vendors supplying scheduling, information, or ticketing solutions
• Mobility-as-a-Service (MaaS) Providers integrating multimodal networks

Practical Implications

Adopting 16614-1 streamlines how infrastructure and operational data are exchanged across platforms, facilitates digital twins for network planning, and accelerates innovation in areas like journey planners and accessibility mapping.

ISO/TS 24854-5:2026 – ITS Facilities Layer Services – Message Sets

Full Title: Intelligent transport systems — Facilities layer services — Part 5: Message sets

Scope and Purpose

ISO/TS 24854-5:2026 sets out the structure and requirements for creating and managing intelligent transport system (ITS) message sets (ITS-MsgSets) at the facilities layer. These message sets ensure that ITS stations—found in vehicles, road infrastructure, and control centers—can exchange information robustly, flexibly, and securely using standardized protocols. This drastically reduces communication overhead, facilitates interoperability, and underpins effective, scalable ITS operations.

This standard bridges the gap between ITS architecture (ISO 21217) and practical ITS deployment, guiding how messages are constructed, uniquely identified, versioned, and transmitted efficiently—especially in complex connected vehicle and smart city contexts.

Key Requirements and Specifications

• Structured Message Definition: Uses ASN.1 to formally define message sets and identifiers, ensuring unique identification and precise versioning.
• Efficient Message Concatenation: Allows the creation of protocol data units (PDUs) by concatenating messages from different ITS-MsgSets, reducing security and processing overheads.
• Compatibility and Registration: Leverages ISO 17419 for global unique identification and registry, and supports major regional protocols (ETSI, DSRC, SAE J2735).

Who Needs to Comply?

• ITS Equipment Manufacturers (vehicle, roadside, infrastructure)
• ITS System Integrators and Software Providers
• Authorities and Operators deploying connected vehicle services
• Smart Mobility Platform Developers

Practical Implications

Implementing ISO/TS 24854-5 ensures that your ITS systems can exchange messages dynamically, handle multiple protocol versions, and optimize bandwidth—a “must-have” for scaling up smart, connected transport operations.

Notable Features

• Clearly defined ASN.1 message encoding for formal interoperability
• Dynamic PDU creation for efficient communication
• Strong versioning and registries prevent message collisions

Key highlights:

• Enables robust, extensible ITS message exchange
• Reduces operational bandwidth and enhances system security
• Essential for future-proofing smart city and mobility deployments
