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.

The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types of ISO document should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).

ISO draws attention to the possibility that the implementation of this document may involve the use of (a) patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a) patent(s) which may be required to implement this document. However, implementers are cautioned that this may not represent the latest information, which may be obtained from the patent database available at www.iso.org/patents.

This document was prepared by Technical Committee ISO/TC 204, Intelligent transport systems, in collaboration with the European Committee for Standardization (CEN) Technical Committee CEN/TC 278, Intelligent Transport Systems, in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).

This second edition cancels and replaces the first edition of ISO 14907‑1:2020, which has been technically revised.

The main changes are as follows:

the presentation of the different test groups has been modified to consistently reflect their typical sequence (i.e. pre-, functionality- and quality-related tests);
terms and definitions have been updated and ISO 17573‑2 has been included as the primary source for harmonized terminology across electronic fee collection (EFC) standards;
the references have been revised.

Introduction

For an electronic fee collection (EFC) system, approvals and tests are required to determine whether the system (or individual components of the system) conforms to standards and application requirements and to enable parameters such as quality, availability, and maintainability to be measured.

This document provides a toolbox of tests and procedures for the assessment and proof of EFC systems that they are suitable for specified EFC applications under specific operational conditions. Depending on the system to be tested and based on available documentation and the status of previous approvals, this document helps interested parties, such as system suppliers, operators and testing institutes, make use of already proven references and identify parameters that still need to be tested according to the specified intended use.

At the time of publication of this document, the determination of common system requirements for Europe (or any other region) has not been agreed. For this reason, no specific performance requirements are set out in this document, unless these are already determined elsewhere (such as safety or radio regulations), but instead the most important parameters that should be included in such requirements specifications are stated. Where reference to an existing test is available, this document provides that reference. This document defines only the test and test procedures, not the benchmark figures that these intend to be measured against. Benchmark figures which the systems or components under test can be compared with and validated against will potentially form the subject of a future part of the ISO 14907 series. Within the framework of the European Electronic Toll Service (EETS), this document can provide a basis for the certification of the various systems' part of the EETS, in particular for assessing their suitability for use.

This document is furthermore limited to automated (electronic) payment using a standardized dedicated short-range communication (DSRC). The scope of this document does not include manual payment, conventional money transaction, nor payment by means of sticker, vignettes, tickets, or magnetic-stripe cards, etc. The applications to which EFC is related are toll collection, road pricing, parking, and individual traffic information.

This document supports groups of operators to determine common specific performance levels and operating conditions, while allowing for regional variation where needed. It provides operating and environmental parameters (or classes of operating and environmental parameters) within which such systems operate without impairing interoperability.

The following guidelines have been followed when selecting the test procedures for test parameters:

as far as possible, reference is made to existing standardized test procedures;
the focus is placed on those tests that are essential to ensuring that EFC equipment can exchange information and mutually use the exchanged information.

An overview of the tests and parameters provided by this document is given in 5.1 and 5.2.

A brief guide describing how to use this document is provided by Annex A.

While this document relates to general test procedures, some provisions relate specifically to test procedures for certification purposes. Many parts of this document are relevant internationally, but adaptations can be necessary to meet regulations outside Europe Economic Area (EEA).

ISO/TS 37444 provides an examination framework for EFC charging performance.

This document relates only to the equipment of the user and the service provider as illustrated in Figure 1.

The scope of this document relates solely to on-board equipment (OBE) and roadside equipment (RSE), and the DSRC interface between OBE and RSE including its functions to perform the fee collection as illustrated by Figure 2.

1 Scope

This document specifies the test procedures for roadside equipment (RSE and on-board equipment (OBE for electronic fee collection (EFC) with regard to conformance to standards and requirements for type approval and acceptance testing.

The scope of this document is restricted to systems operating within the radio emission, electromagnetic compatibility (EMC) regulations, traffic, and other regulations of the regions in which they are operated.

This document identifies a set of suitable parameters and provides test procedures to enable the proof of a complete EFC system, as well as components of an EFC system, e.g. OBE, related to the defined requirements of an application. The defined parameter and tests are assigned to the following groups of parameters:

functionality;
quality;
referenced pre-tests.

This document describes procedures, methods and tools, and a test plan which shows the relation between all tests and the sequence of these tests. It lists all tests that are required to measure the performance of EFC equipment. It describes which EFC equipment is covered by the test procedures; the values of the parameters to be tested are not included. It also describes how the tests are intended to be performed, and which tools and prerequisites are necessary before this series of tests can be undertaken. It is assumed that the security of the system is inherent in the communications and EFC functionality tests, therefore they are not addressed in this document. All tests in this document provide instructions on how to evaluate the test results.

This document defines only the tests and test procedures, not the benchmark values against which they are intended to be measured. The test procedures defined in this document can be used as input, e.g. by scheme owners, for prototype testing, type approvals, tests of installations and periodic inspections.

Related to a conceptual model of an EFC system, this document relates only to the equipment of the user and the service provider.

EFC systems for DSRC consist, in principle, of a group of technical components, which in combination fulfil the functions required for the collection of fees by electronic automatic means. These components comprise all, or most, of the following:

OBE within a vehicle;
OBE containing the communications and computing sub-functions;
optional integrated circuit card which can carry electronic money, service rights, and other secured information;
communication between OBE and RSE based on DSRC;
equipment for the fee collection at the RSE containing the communications and computing sub-functions;
equipment for the enforcement at the roadside;
central equipment for the administration and operation of the system.

The scope of this document relates solely to OBE and RSE and the DSRC interface between OBE and RSE including its functions to perform the fee collection. All the equipment used for enforcement (e.g. detection, classification, localization, and registration) and central equipment are outside the scope of this document.
