Introduction
Environmentally friendly and energy-efficient mobility services have been deployed around the world due to
rising urban energy problems caused by population growth, rapid climate change, and increased our energy
use. While transportation and energy technical solutions are attempting to converge for energy efficiency,
there are no traffic-energy-related guidelines for the various needs of diverse stakeholders in the business.
Under these circumstances, Smart City deals with foundation technologies for energy-efficient management
based on total energy measurement, energy metering, energy demand forecasting, and data platforms in the
transportation sector, which can be presented as management requirements for solving urban problems.
Energy-based Green-ITS service in Smart City provides users with customized services for each energy
demand by informed energy in the transportation sector and integrating management based on nomadic
devices to maximize the energy utilization efficiency in the transportation sector.
ISO 17748 provides various information and references to support the implementation of applications related
to standardized access to framework for energy-based G-ITS using personal ITS stations. It consists of the
following parts.
— — Part 1: General information and use case definitions
This part provides the overview of ISO 17748, general information including the conceptual aspects, set and
framework along with the use case definitions and common set of resources (definitions, references), which
are used for all subsequent parts.

— — Part 2 (this document): Functional requirements of data platform
This part specifies all functional requirements of the data platform related to the integrated mobile service
application for energy-based G-ITS to be used on the nomadic devices and to be interfaced with smart city and
utilities (electric charging stations, vehicle ITS stations, etc). The guidelines reflect the user services from the
use cases as defined in ISO/TR 17748-1.

— — Part 3: Data exchange requirements for electric vehicle (EV)-based demand response charging services
This part specifies dataset definitions and data procedures related to DR (Demand Response) services
specified in ISO/TR 17748-1. In addition, data interfaces using the data platform specified in ISO/TS 17748-2
are presented.
— — Part 4: Service framework for sustainable urban public transport operation and management
This part defines the service framework for sustainable urban public transport operation and management. It
also defines the data, interfaces, and functions of the framework for urban public transportation operations
and management utilizing nomadic devices between users, service providers, data platform, and cloud server.

Functional requirements of data platform
1 Scope
This document specifies functional requirements for data platforms to support connectivity among nomadic
devices, smart city cloud server and mobility service provider for energy-based green ITSintelligent transport
systems (ITS) services which are defined in ISO/TR 17748-1. In addition, it also delivers related guidelines
required to develop and operate the data platform among nomadic devices, smart city cloud and mobility with
intelligent transport systems(ITS)ITS technologies.
The data platform aims to accommodate the specific needs of energy-based green ITS service to manage total
energy capacity in smart city. The data platform focuses on the use of data exchange functional requirement
standards between eco-mobility and nomadic devices to enable the development of cloud-based ITS using
wireless networks.

5 Framework of energy-based G–ITS services
5.1 Interconnection of stakeholders for energy-based G-ITS services
As defined in ISO/TR 17748-1:2024, the energy-based Green ITS (G-ITS) services are operated through four
primary stakeholders: smart city cloud, data platform, service provider, and user. The relationship structure
among stakeholders, focused on the data platform, is illustrated in Figure 5.1Figure 5.1.

ISO/DTS 17748-2:(en)
Figure 5.1 – — Interconnection of stakeholders for energy-based G-ITS services
Smart city cloud exchanges data with external organizations such as the monitoring and control (MC) centres
and the meteorological agency, and covers data across various domains, including energy, transportation, and
weather. When an event occurs— — such as an energy shortage or a surge in energy demand— — the smart
city cloud sends a corresponding notice to the data platform.
The data platform is an independent concept from the smart city cloud. It performs specific and detailed data
processing procedures in order for service providers to deliver the G-ITS services defined in Part ISO/TR
17748-1 to users. Even in the absence of a smart city cloud, a data platform is required to generate information,
routes, and other outputs that meet user needs by utilizing external data sources such as meteorological
agencies, police agencies, and ITS centres.
In other words, the smart city cloud serves as a comprehensive repository and management system for data
to ensure the efficient operation of urban ITS, while the data platform directly analyses the data and derives
useful information.
Service provider uploads specific service information (such as service area, service type, and service
description) to the smart city cloud. The service provider also transmits specific service information to the
data platform so that the platform can generate the information required for the services they provide—
information that meets user needs—such as the location of electric vehicle charging stations, carbon emission
trading data, or available car-sharing options
User registers an account for service use through the nomadic or/and mobile device and inputs requirements
for mobility or infrastructure use on their personal preference or status.
5.2 Functional roles of stakeholders for energy-based G-ITS services
Each four stakeholders should have functions required for the operation and management of the data
platform. The functions to be performed by each stakeholder are specified in Table 5.1Table 5.1.
