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

Introduction
0.1 System overview
The ISO 24315 series on the management of electronic traffic regulations (METR) is intended to provide
users access to geo-specific, trustworthy, timely, authoritative and machine-interpretable rules relating to
traffic and transport, enacted by jurisdictional entities, including those who define rules for campuses (i.e.
private grounds). This is conceptually shown in Figure 1.
Figure 1 — METR concept
0.2 Purpose
METR is designed to assist developers and manufacturers of driving automation systems (i.e. automation
Levels 1-5) and driver information systems (including those at automation Level 0) to electronically obtain
traffic rules to better enable them in:
a) interacting safely with other road users;
b) following instructions from law enforcement organizations and those authorized to direct traffic;
c) maintaining smooth and safe flow of traffic; and
d) complying with other rules enacted to support legislative policies (such as environmental protection,
noise, height and weight restrictions, and societal aspects such as market days, fiestas, pedestrian
[1]
zones, etc.).
METR is designed to provide a reference framework for the trustworthy distribution of electronic versions
of legal traffic rules. The content and application of these traffic rules is outside of the scope of standards
and specifications on METR.
0.3 Flow of information
The general flow of METR information is illustrated in Figure 2 and is described below the figure.
v
Figure 2 — METR flow of information
a) METR starts with rule makers defining and enacting rules that are relevant to transport users.
b) Each legal rule is translated into a METR rule, which is a secure, standardized electronic representation
that includes a digital signature of the rule signing organization.
c) METR rules are collected for a geographic area(s) and specific scope(s).
d) Rules are distributed to METR users based on their needs.
e) METR users become aware of the METR rules, verify their authenticity and respond appropriately.
f) As needed, METR users can submit discrepancy reports to a discrepancy handler for investigation and
correction.

0.5 Rule distribution
Electronic traffic rules and their distribution have three orthogonal characteristics that are often confused
with one another.
a) Electronic rules can be pre-announced (i.e. known and publicized well in advance of the user's need)
or emergent (i.e. publicized and needed while previously obtained pre-announced rules are still
considered fresh).
vii
b) Electronic rules can be distributed through a wide-area distribution mechanism or a local distribution
mechanism.
c) Electronic rules can be pulled by users well in advance of their need or pushed to users as special
conditions necessitat
