Overview

EN ISO 14814:2006 - Road transport and traffic telematics: Automatic Vehicle Identification (AVI) and Automatic Equipment Identification (AEI) - defines a reference architecture and terminology to achieve unambiguous identification in ITS/RTTT environments. The standard provides an enabling, non‑prescriptive framework that supports interoperability across commercial AVI/AEI systems without mandating air‑interface frequencies or protocols. It focuses on data constructs and identification schemes that can scale from simple read‑only tags to complex bidirectional ITS messages.

Key topics and requirements

• Reference architecture model: conceptual, functional, data, application and implementation architecture layers are defined to guide system design and integration.
• Unambiguous identification: a common numbering and data construct identifies On‑Board Equipment (OBE), tags or transponders and marks the content as an ITS/RTTT message.
• Data construct and encoding: the standard recommends use of ASN.1 (ISO/IEC 8824 and 8825) for data element definition and encoding to maximise interoperability and minimise transmission/storage overhead.
• Flexibility and scalability: supports high population capability and upward migration from simple AVI/AEI devices to more capable systems.
• Protocol and media independence: not tied to any specific air interface or frequency; enables multiple media and legacy system support.
• Read/write and read‑only operation: numbering and data structures work with both device types.
• EDI compatibility: identifies ITS/RTTT message structures suitable for electronic data interchange and system integration.

Practical applications and users

• Typical use cases:
  • Road charging and tolling
  • Parking management
  • Vehicle fleet and asset management
  • Traffic control and information systems
  • Automatic fee collection and enforcement
  • Intermodal goods transport identification
• Primary users:
  • ITS architects and system integrators
  • Toll operators, road authorities and transport agencies
  • OBE/tag manufacturers and hardware vendors
  • Software developers for backend ITS services and data registries
  • Standards bodies and procurement teams ensuring interoperability

Benefits

• Enables cross‑vendor interoperability and long‑term migration paths
• Provides a stable, protocol‑neutral data model for ITS message exchange
• Reduces integration risk in multi‑jurisdictional or multi‑vendor deployments
