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).

Introduction
Environmentally friendly and energy-efficient mobility services have been deployed around the world to
address rising urban energy problems caused by population growth, rapid climate change and increased
energy use. While attempts are being made to combine technical solutions for transportation and energy
use for improved energy efficiency, there are no traffic-energy-related guidelines that meet the various
needs of diverse stakeholders in the transportation industry.
A smart city uses foundation technologies to manage energy efficiency. A smart city does this by measuring,
metering and forecasting demand for energy, and by providing data platforms on the transport sector. These
can be presented as management technology for solving urban problems.
An energy-based green intelligent transport systems (G-ITS) service provides users with customized
services to meet their energy needs. The service does this by keeping users informed about their energy use
and integrating management using nomadic devices to maximize energy efficiency.
This document considers the conversion of the existing efficiency and safety-oriented transportation
system into a more energy-efficient system through the distribution of urban energy, allowing for improved
management and energy consumption measurements.
Specifically, this document:
— identifies the general information of the applicable framework for energy-based green intelligent
transport systems(G-ITS) services;
— identifies the method to describe the general information for all subjects related to energy-based G-ITS
services interfaced with smart city cloud and charging infrastructure, with vehicle stations based on
nomadic devices;
— specifies the general use cases for inclusion in energy-based G-ITS as services.

Part 1:
General information and use case definitions
1 Scope
This document provides a framework and information on the total amount of energy appropriate for the
deployment of smart city mobility and energy efficiency technologies. These technologies can increase
operational energy efficiency and unlock enhanced transportation waste-free energy applications, as well
as measuring energy consumption.
The standard framework for energy-based green intelligent transport systems (G-ITS) builds on the best
practices for energy efficient transport and management systems, as well as applications of intelligent transport
systems (ITS), and aims to accommodate the specific needs of energy-based green ITS in smart cities.
G-ITS use data platforms to measure energy for transport and to forecast demand. A smart city provides G-ITS
services to improve energy efficiency by using nomadic devices and by monitoring energy supply and demand.
This document describes the change in the traffic paradigm from the perspective of energy efficiency. It
outlines:
— general information for energy-based G-ITS as a service using nomadic and mobile devices;
— use cases for energy-based G-ITS services using nomadic and mobile devices;
— use cases for energy-based mobility services, for example electric vehicles (EV), transportation
infrastructure and other mobility services using nomadic devices.

4 General information on energy-based green intelligent transport systems
4.1 Overview of energy-based G-ITS
4.1.1 The background and challenges of energy-based G-ITS
The increase in urbanization due to population growth, energy depletion, rising carbon emission and traffic
congestion contributes to climate change and affects cities and local communities. Cities are addressing
these issues by adopting environmentally friendly and energy-efficient ITS services.
For example, mobility ecosystems have been created where various mobility services can be accessed
through mobile apps or web interfaces, providing energy-efficient routes and optimizing travel routes while
allowing users to pay for the most suitable mobility services in terms of time and cost.
Additionally, efforts to reduce carbon emissions have been made, including a shift from fossil fuel energy
sources to electricity. Various electric mobility services are emerging, contributing to the overall energy
management of cities.
It is expected that numerous convergent services will emerge for decarbonization in transportation and
energy. However, there is currently a lack of guidance to meet the diverse demands of these services. It
is necessary to develop several leading service models for traffic energy management, including mobile
charging vehicles, charging with renewable energy, and total energy consumption control in the public
transportation sector.
4.1.2 The energy-based G-ITS concept
4.1.2.1 General
Some conceptual aspects of energy-based G-ITS services are illustrated in Figure 1.

Figure 1 — Conceptual aspects of energy-based G-ITS
An energy-based G-ITS service consists of a data platform for smart cities that balances energy supply
and demand using new information and communication (ICT)-based technologies such as smartphones,
integrated data platforms and connected vehicles. To transform the existing paradigm of traffic efficiency
and safety into an energy efficient system, an energy-based G-ITS service aims to allocate and distribute
urban energy to manage the energy use of individuals. An energy-based G-ITS also supports the real-time
operation management of complex transportation through connection with information systems such as
generator information, system price informa
