Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies

(ISO member bodies). The work of preparing International Standards is normally carried out through ISO

technical committees. Each member body interested in a subject for which a technical committee has been

established has the right to be represented on that committee. International organizations, governmental and

non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the

International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.

International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.

The main task of technical committees is to prepare International Standards. Draft International Standards

adopted by the technical committees are circulated to the member bodies for voting. Publication as an

International Standard requires approval by at least 75 % of the member bodies casting a vote.

Attention is drawn to the possibility that some of the elements of this document may be the subject of patent

rights. ISO shall not be held responsible for identifying any or all such patent rights.

ISO 14815 was prepared by the European Committee for Standardization (CEN) Technical Committee

CEN/TC 278, Road transport and traffic telematics, in collaboration with Technical Committee ISO/TC 204,

Intelligent transport systems, in accordance with the Agreement on technical cooperation between ISO and

CEN (Vienna Agreement).

This first edition cancels and replaces ISO/TS 14815:2000, which has been technically revised.

Introduction
System specification

This International Standard is designed to enable users and suppliers of AVI/AEI systems to specify system

specification that will enable a nominal interoperability based on a DSRC link.

The terms “AVI” and “AEI” are used both to describe “independently functioning AVI/AEI systems” and as “the

function of identification within other RTTT/TICS systems”. This International Standard supports both such

uses where no other application or sector standard applies.

Whilst it may be desirable to determine a single set of requirements for operation in all environments and

under all operating conditions, this could impose unacceptable costs.

This International Standard therefore provides standard “classes” for different aspects of system specification,

such that a system specifier may select the appropriate performance parameters to meet a particular

requirement. Supporting informative annexes also provide a number of general use “categories” which may be

used to specify the environmental and operating parameters to support interoperable applications.

The architecture descriptions provided in this International Standard are in compliance with the guidelines

provided by CEN/TC 278 WG13 ISO/TC 204 WG1.

For the data structure elements, Abstract Syntax Notation One (ASN.1) Packed Encoding Rules (PER)

(ISO 8825-2) are used. This usage provides maximum interoperability and conformance to existing standards.

For detailed information on the use of ASN.1 PER for AVI/AEI applications, reference is made to ISO 14816.

This International Standard provides classification procedures and details test requirements needed to support

system definition. These requirements are, wherever possible, determined by reference to existing standards

and established practices.
Test requirements

Test requirements are determined for AVI/AEI system components. The requirements to meet this

International Standard encompass general performance measurement, operational, and environmental

aspects.
How to use this International Standard

It is also an objective to provide users with different applications and in different environmental circumstances

a useful tool that is flexible enough to serve the various different needs. The categorization and classification

system in this International Standard provides for this.

A brief guide showing how to use this International Standard is provided at the end of Annex A.

INTERNATIONAL STANDARD ISO 14815:2005(E)
Road transport and traffic telematics — Automatic vehicle and
equipment identification — System specifications
1 Scope

This International Standard defines a generic AVI/AEI System specification for nominal AVI/AEI to provide an

enabling International Standard, which, whilst allowing the system specifier to determine the performance

levels and operating conditions, provides a framework for nominal interoperability.

Within the road context of the Transport and Traffic Telematics Sector, AVI and AEI systems have the specific

objective of achieving a unique or unambiguous positive identification of a vehicle or item of equipment, and to

make that identification automatically.

Whilst AVI may also be seen as an essential component of some applications, the particular needs of such

systems are outside the scope of this International Standard. As far as is possible, care is still taken to provide

a useful tool for such applications.

This International Standard only refers to AVI/AEI in the road environment. Multimodal and intermodal

exchanges of AVI/AEI are outside the scope of this International Standard.

Where AVI/AEI applications are part of a larger system, and where no standardized application-specific test

requirements exist, these test requirements apply.

Anonymity and privacy issues are discussed in ISO 14816, and are not handled in this International Standard.

This International Standard is designed for system specification that will enable a nominal interoperability

based on a DSRC link. AVI/AEI systems that are relying on other link types are outside the scope of this

International Standard for those parameters where the link type influences parameters.

The scope of this International Standard is confined to generic AVI/AEI system specification for systems that

have the following “core” components:

 A means of communication between the vehicle/equipment and the reading station (e.g. a DSRC link);

 operation within a reference architecture which enables compatible systems to read and interpret the

identification (See ISO TR 14814);

 compliance to commonly understood data structures that enable meaningful interpretation of the data

exchanged in the identification sequence (See ISO 14816);

 the provision of operating and environmental parameters (or classes of operating parameters) within

which such systems must successfully function without impairing interoperability. This is to ensure that

the system specifier can state his requirements clearly to Implementation Designers and Integrators, and

measure the performance of such systems (covered in this International Standard).

6 Requirements
6.1 Generic system specification for AVI/AEI systems

This clause summarizes the generic system specification for AVI/AEI systems in terms of functions supported,

data exchanges, categorization and classification. The requirements defined in this clause:

 provide operation within the reference architecture defined in ISO/TR 14814,
 allocate application data in accordance with ENV ISO 14816, and
 enable nominal interoperability.

To obtain interoperability, it is a requirement that nominal AVI/AEI system FE shall have the capability to

operate with nominal AVI/AEI system OBE, albeit of different capability using an air interface as referenced

in 6.5.

However, the environmental and operating conditions within which such equipment has to function may be

different according to geographical location, traffic operating conditions, etc. This International Standard

provides environmental/operational classes grouped into categories to enable the marketplace to decide the

most appropriate FE for individual fixed locations. This is with the knowledge that, within the

operating/environmental constraints selected, any properly configured standard compliant AVI/AEI system

OBE shall have the capability to be identified by all standard compliant AVI/AEI system FE.

To obtain nominal AVI/AEI system interoperability, it is a requirement that OBEs shall have the capability to

operate with nominal AVI/AEI system FE.

However, the environmental and operating conditions within which on-board equipment has to function may

be different according to geographical location, vehicle or equipment type, OBE location, etc. This

International Standard provides options and environmental/operational classes to enable the marketplace to

select the most appropriate OBE equipment, with the knowledge that, within the operating/environmental

constraints selected, any properly configured standard compliant AVI/AEI system FE shall have the capability

to identify all standard compliant AVI/AEI OBEs passing within its compass.

These generic system specifications provide a migration path to later generations of equipment and to

equipment of greater capability.

In order to enable an AVI/AEI system to operate across wide areas, it is necessary for the system to use the

standardized interfaces architecture and data structures normalized in this family of AVI/AEI European

Standards. As particular system specifications will vary, well-declared and flexible structures are used. It is

important, for example, that AVI/AEI system FE facilities can effectively operate different variants of OBE. The

system specification defined in this International Standard supports the numbering schemes and data

structuring defined in ISO 14816.

ISO 14815:2005(E)
6.2 System specification: architecture
It is the Vision of the AVI/AEI system specification International Standard to:

“provide a method (trans-national and interoperable) of automatically identifying a vehicle or item of equipment

using a standard DSRC link.”

Other subsequent standards may determine requirements for AVI/AEI systems working at other air interfaces.

It is the Mission of the AVI/AEI system specification International Standard to:

“Define the functionality, environmental and operating parameters (system specification for AVI/AEI) such that

they may achieve the objectives of the Vision Statement in an Open Systems Environment, enabling

interoperability, whilst retaining the ability for different equipment to coexist.”

According to the operational situation, AVI/AEI systems may be viewed either as a service to support an

application (such as the vehicle identification component in a public transport system or freight management

system), or as an application in itself (for example, the identification of a “probe” vehicle in a traffic

management situation or in an enforcement situation). As such, the AVI/AEI system function may be achieved

using purpose-specific dedicated equipment (such as an AVI/AEI system transponder), or may be achieved

using equipment installed for the application that it supports, or indeed, using existing equipment installed for

another application (such as a freight logistics system utilizing AVI techniques). Such multi-application support

and interoperability will be particularly common in respect of the OBE, although it will also be required in

respect of the FE.
