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 documents 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).
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. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation on the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to the
World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see the following
URL: www.iso.org/iso/foreword.html.
This document was prepared by Technical Committee ISO/TC 204, Intelligent transport systems.
This first edition of ISO/TR 16401-2 cancels and replaces ISO/TS 16401-2:2012, which has been
technically revised.
The main changes compared to the previous edition are as follows:
— conversion from a Technical Specification to Technical Report has been made;
— the terms and definitions have been revised;
— editorial and formal corrections as well as changes to improve readability have been made.
A list of all parts in the ISO 16401 series can be found on the ISO website.

Introduction
This document is part of a set of standards that supports interoperability of autonomous electronic fee
collection (EFC) systems. Autonomous systems use satellite positioning, often combined with additional
sensor technologies such as gyroscopes, odometers, and accelerometers, to localize the vehicle and to
find its position on a map containing the charged geographic objects, such as charged roads or charged
areas. From the charged objects, the vehicle characteristics, the time of day and other data that are
relevant for describing road use, the tariff and ultimately the road usage fee are determined.
The ISO/TR 16401 series provides tests to assess the Front End Communications API and Front End
application behaviours compliancy towards the requirements listed in ISO 17575-2. ISO/TR 16401-1
contains the definition of such tests in the form of test purposes, listing the initial conditions, references
and individual steps in a structured textual manner. This document contains the identical tests written
in Testing and Test Control Notation version 3 (TTCN-3).
Autonomous on-board equipment (OBE) operates without relying on dedicated road-side infrastructure
by employing wide-area technologies such as Global Navigation Satellite Systems (GNSS) and Cellular
Communications Networks (CN). Therefore, autonomous systems may also be referred to as GNSS/CN
systems.
Within the suite of EFC standards, this document defines tests for conformity evaluation of Front End
and Back End that comply with the requirements towards the context data specified in ISO 17575-2.
This document is intended to
— assess Front End Communications API and Front End application capabilities,
— assess Front End Communications API and Front End application behaviour,
— serve as a guide for Front End Communications API and Front End application conformance
evaluation and type approval,
— achieve comparability between the results of the corresponding tests applied in different places at
different times, and
— facilitate communications between parties.
