Overview
EN ISO 14816:2005/A1:2019 is an amendment to the international standard EN ISO 14816 (ISO 14816:2005) that governs automatic vehicle and equipment identification (AVIE) for road transport and traffic telematics. Approved by CEN in 2019, this amendment updates ASN.1 data definitions, encoding assumptions and several data-field structures used for numbering and data exchange in intelligent transport systems (ITS).
Key topics and technical changes
- ASN.1 data module updates - Annex B provides an updated ASN.1 module (AVIAEINumberingAndDataStructures) that defines the CS (coding structure) types CS1…CS8 used for AVIE payloads.
- Encoding assumption clarified - Examples and implementations now assume ASN.1 PER unaligned encoding.
- Revised normative references - Some ASN.1 references (ISO/IEC 8825 parts) are deleted or moved to the bibliography; ISO/IEC 8859-1 remains referenced for character encoding of time strings.
- Updated data-field formats and sizes - Amendment A1 revises minimum sizes and bit/byte layouts for coding structures, including:
- CS5 (vehicle identification) - VIN defined as a 17-character VisibleString.
- Freight container data (CS7 / FreightContainerData) - detailed fields (owner code, serial number, check digit, dimensions, type code, masses) with specified bit lengths and an overall 12-octet layout.
- CS8 (tax/vignette data) - includes countryCode and taxCode with defined fill bits.
- Time format - StartTime/StopTime use an AviEriDateTime OCTET STRING (SIZE(10)) with format YYMMDDhhmm (ISO/IEC 8859-1 encoding).
- Bit-field definitions - GeoGraphicalLimit and ServiceApplicationLimit are defined as 8-bit BIT STRINGs with enumerated restriction flags (e.g., globalRestriction, regionalRestriction, notForPrepayment, notForVehicleaccess).
Practical applications
- Tolling and electronic vignettes (tax/vignette data structures)
- Automatic vehicle identification for access control, fleet management and parking systems
- Freight tracking and intermodal logistics (container numbering and container metadata)
- ITS device and reader manufacturers implementing interoperable AVIE tags and readers
- Software developers and system integrators encoding/decoding AVIE payloads using ASN.1 PER unaligned
Who should use this standard
- Transport authorities and toll operators defining data formats for AVIE services
- ITS solution architects and system integrators
- Vehicle and equipment manufacturers implementing onboard identifiers (VIN mapping)
- RFID/NFC/DSRC tag and reader vendors ensuring cross-border interoperability
- Standards teams referencing ASN.1 modules and bit-level field definitions
