Overview
EN ISO 17264:2009 / ISO 17264:2009 defines the application interfaces and transaction requirements for interoperable Automatic Vehicle Identification (AVI) and Automatic Equipment Identification (AEI) within Intelligent Transport Systems (ITS). The standard specifies common AVI/AEI transaction steps (read and read/write profiles) and the AVI/AEI application interface to standardized wireless protocols (the “air interface”) so different service providers and vendors can interoperate. It is an interface standard following the OSI philosophy and therefore does not mandate implementation choices on either side of the air interface between Fixed Equipment (roadside) and On‑Board Equipment (OBE).
Key topics and technical requirements
- Transaction profiles: Defines two core profiles - AVI/AEI Read and AVI/AEI Read & Write - covering collection and update of data stored in OBE consistent with ISO 14816 and related numbering/data structures.
- Air interface abstraction: Specifies the application-layer interface mapped to standardized wireless protocols (reference point DELTA in ISO 14814) to enable cross-vendor communication without prescribing lower-layer implementations.
- Interoperability: Requires clear definition of attributes, actions, service primitives and protocol implementation conformance statements (PICS) to indicate supported optional features.
- Conformance: Equipment may claim conformance to the standard; note that the standard itself does not define specific performance tests.
- Architecture and mapping: Annex A maps the AVI/AEI application interface to DSRC application-layer (EN 12834 / ISO 15628). Annex B addresses mappings to ISO/IEC 18000 air interfaces (e.g., 13.56 MHz, 2.45 GHz, 860–960 MHz, 433 MHz families). Annex C provides transaction examples.
- Terms and data model: Uses standardized terms (OBE, RSE, reader, element, attribute) and refers to ASN.1 for data syntax where applicable.
Practical applications and users
Who uses EN ISO 17264:
- ITS system integrators and solution architects designing roadside-to-vehicle communications
- Roadside equipment (RSE) and on‑board unit (OBU) manufacturers implementing AVI/AEI functionality
- RFID and wireless protocol vendors mapping products to ITS application interfaces
- Transport authorities and service providers requiring multi-vendor interoperability (tolling, access control, fleet management, ERI/registration)
- Test labs and conformance assessors preparing protocol implementation conformance statements
Practical benefits:
- Enables cross-vendor interoperability of AVI/AEI services
- Standardizes transaction steps and data attributes for reliable vehicle/equipment identification
- Facilitates multi-technology deployments by mapping the application interface to DSRC and ISO/IEC 18000 air interfaces
