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

ISO/DIS 37181:2021(E)
Introduction

Various countries are facing critical issues as their population ages, often at a rate higher than expected.

One of the challenges is the shortage of manpower, where many sectors, including transportation, face

constraints. At the same time, as their economic activities expand, travel demands have also become

more diversified, thus imposing additional demand on transportation networks. These challenges are

especially acute for cities, where increased transportation needs have brought about traffic congestion

and led to poorer quality of life.

To overcome such challenges, cities have tried to improve transportation systems in a variety of ways,

investing in mass transit ranging from light rail transit to metro as well as in public bus services. In

mass transit, Automatic Train Operation (ATO) has been widely used for decades. ATO deployed are

mostly at Grade of Automation 4 i.e. Unattended Train Operation (UTO) nowadays, where the system is

fully run without any staff on board as introduced into the metro in Barcelona, Copenhagen, Hong Kong,

Sao Paulo, Singapore, Tokyo and Vancouver.

Beyond mass transit, transportation services on public roads have potential to be automated as well.

Autonomous shuttle services are in operation as a means to provide first and last mile connectivity

between transport nodes and homes or work places as well as transport services within designated

areas such as campuses, parks and neighbourhoods. Such services have already been deployed in

Beijing, Las Vegas, Melbourne, Nice and Singapore.

Smart transportation by autonomous vehicles will work as solution to transportation issues and

concerns in cities. However, the outcomes can be achieved only when autonomous vehicles are applied

under organised conditions with safety as a top priority. This document describes the concept of smart

transportation and aims to accelerate the proper introduction of autonomous vehicles onto public roads.

Smart community infrastructures — Smart transportation by
autonomous vehicles on public roads
1 Scope

This document describes the concept and goals of smart transportation by autonomous vehicles on

public roads. It provides guidelines for the successful introduction and organisation of autonomous

vehicles, with the aim of enhancing safety of public road transportation and addressing city challenges

such as aging population and diverse travel demands.

This document focuses on the deployment of autonomous vehicles as an operational system for actual

use on public roads with indispensable arrangements thereabout. This document is provided to

academia, autonomous vehicle developers, policy makers, research institutions, road infrastructure

operators, public road administrators, testing inspection and certification bodies, and vehicle

manufacturers.

on-road motor vehicles

ISO and IEC maintain terminological databases for use in standardisation at the following addresses:

3.1
autonomous vehicle

vehicle that is capable of sensing its environment and moving safely with no human input and is

designed to be operated by automated driving systems.

Note 1 to entry: Automated driving system in this document means no human intervention system

characterised as SAE levels 4 and 5 that are defined by SAE J3016: 2018.

Note 2 to entry: Autonomous vehicles in this document exclude those applied only in limited areas, such

as vehicles as designated by ISO 37168.
4 Autonomous vehicles as smart transportation
4.1 General

ISO 37154 provides general guidance on smart transportation that aims to solve specific city issues. The

deployment of autonomous vehicles on public roads is considered one of the ways to introduce smart

transportation systems.

NOTE Any transportation technologies or services cannot be used for smart transportation systems, if

their performance is not confirmed, formally documented or published as international or official

standards.
4.2 Autonomous vehicles used in smart transportation

This document describes smart transportation using autonomous vehicles that have been validated for

public road operations based on published international or national standards.

NOTE Autonomous vehicles had been deployed on public roads and the experiences were documented.

For example, public trials were conducted for on-demand autonomous shuttles at Sentosa, Singapore in

The smart transportation system with autonomous vehicles can be introduced into a city in order to

improve connectivity, mainly first and last mile, accessibility to mass transit and other transportation

networks, reduce traffic congestion levels, free up land used for roads and parking lots for othe
