What is ISO 14816- Automatic vehicle and equipment identification about?
ISO 14816 is an International Standard that discusses road transport and traffic telematics.
ISO 14816 establishes a common framework data structure for unambiguous identification in RTTT/ITS systems. It excludes any physical aspects such as interfaces. It is neither frequency- nor air interface protocol-specific.
ISO 14816 defines data structures based on the ISO/IEC 8824-1 ASN.1 UNIVERSAL CLASS types that may be directly IMPORTED to other application standards that would need only subsets of the full APPLICATION CLASS types. These UNIVERSAL CLASS and APPLICATION CLASS types are uniquely defined as an ASN.1 module. This module may be directly linked into an application data definition.
The principles of data element structure and description determined in ISO/IEC 8824 have been adopted to provide an interoperable architecture within a standard framework according to guidelines from ISO/TC 204 and CEN/TC 278.
ISO 14816 defines default encoding for simple AVI/AEI applications where no other relevant application standard exists.
Who is ISO 14816- Automatic vehicle and equipment identification for?
ISO 14816 on road transport and traffic telematics is useful for:
- IT application in transport and trade
- Telecommunications system providers
- Manufacturer/operator with an OBE
- Automotive industry
- Road and traffic authorities
- Regulatory bodies
Why should you use ISO 14816- Automatic vehicle and equipment identification?
ISO 14816 specifies a data structure that helps users to enable upwards integration and expansion from the simplest low-cost AVI/AEI system to more complex functions. The structure is designed to be flexible and enabling rather than prescriptive.
ISO 14816 has been designed to provide users with the differing requirements of AVI and AEI by the use of separate application specifics. By retaining these differing requirements within one supervisory document, the interoperability is maximized, particularly in the case where both AVI and AEI are required at the same time in the road environment.
In order to support systems using both active and passive On-Board Equipment (OBE), the basic data structures have been minimized. This enables any manufacturer/operator with an OBE with an user addressable memory of only 56 bits to be able to conform to a full core identification according to ISO 14816.
Abstract Syntax Notation One (ASN.1) is widely applied and its usage provides maximum interoperability and conformance to existing International Standards, and meets the specifications defined requirements for a generic standard model for RTTT in that it:
- Uses existing standard Syntax Notation and Encoding Rules
- Is adaptable and expandable
- Does not include unnecessary information for a specific system
- Incurs a minimum of overhead in storage and transmission
