ISO/TR 12770:2023(E)
Introduction
Currently, more than 70 % of the world’s people live in cities. The proportion of people living in cities
is rising around the world as civilisations develop and congregate around cities where there are more
employment opportunities. Societies develop more innovatively and rapidly in cities, and they present
better entertainment opportunities, adding to their attraction. The Economist magazine recently
forecast that by 2045, an extra 2 billion people will live in urban areas. The resulting concentration
of population creates various issues such as road congestion due to an increase in vehicle population
and environmental pollution due to exhaust gas and tyre erosion. These issues have been attributed to
increases in the number of delivery trucks, taxis and town centre traffic and are further exacerbated by
obstacles to the effective use of urban space due to the private ownership of cars (parking lots, street
parking).
The pressures caused by scientific advice that significant action and change of behaviour is needed to
ameliorate the adverse effects of climate change require a more environmentally friendly use of the
transport system.
It is recognized that there is also road infrastructure deterioration, a lack of provision of information
on the use of public transportation, driver shortages due to the increase in the number of elderly people
and the inconvenience of multimodal fare payments, and action to improve the situation is urgently
needed.
The International Data Corporation forecasts that of the USD 81 billion that will be spent on smart city
technology in 2020, nearly a quarter will go into fixed visual surveillance, smart outdoor lighting, and
advanced public transit.
Eventually, this is likely to mean high speed trains and driverless cars. Consultancy McKinsey forecasts
that up to 15 % of passenger vehicles sold globally in 2030 will be fully automated, while revenues in
the automotive sector could nearly double to USD 6,7 trillion thanks to shared mobility (car-sharing,
e-hailing) and data connectivity services (including apps and car software upgrades).
Changing consumer tastes are also calling for new types of infrastructure. Today’s city dwellers, for
example, increasingly shop online and expect ever faster delivery times. To meet their needs, modern
urban areas need the support of last-minute distribution centres, backed by out-of-town warehouses.
Therefore, in recent years, in Europe, studies on the development of mobility integration standards have
been active to solve urban problems. There are various movements around the world making efforts to
address these issues. In the United States, intelligent transport systems (ITS) technology is used to
try to solve these urban problems, as in the Smart City Pilot Project. Columbus, Ohio has been selected
as a smart city pilot project which is currently being designed in detail. Important key factors here
are the core architectural elements of smart cities, and urban ITS sharing of probe data (also called
sensor data), connected cars and automated driving. In addition, new issues have been recognized
with the introduction of the connected car to the real world in respect of privacy protection, the need
to strengthen security measures, big data collection and processing measures, which are becoming
important considerations.
In terms of the effective use of urban space, it is hoped that the introduction of connected cars and
automated driving can significantly reduce the requirements for urban parking lots (redistribution of
road space). If technology can eliminate congestion, the city road area usage can also be minimized and
reallocated (space utilization improvement) to improve the living environment of, and quality of life
in, the city. In addition, the environment around the road will be improved by improving enforcement
(e.g. overloaded vehicles). On the other hand, even in rural areas, it is possible to introduce automated
driving robot taxis and other shared mobility that saves labour (and is therefore more affordable) and
improves the mobility of elderly people.
To achieve this requires the realization of various issues, for example:
— cooperation with harmonization of de-jure standards such as ISO and industry de facto standards;
vi
© ISO 2023 – All rights reserved
---------------------- Page: 6 ----------------------
ISO/TR 12770:2023(E)
— recognition of the significance of international standardization (e.g., to reduce implementation
costs);
— recognition of the significance of harmonization activities by countries around the world;
— cooperation and contribution between ISO/TC 22 for in-vehicle systems and ISO/TC 204 for ITS
technology.
As mentioned above, automated driving mobility is expected to play an important role both in cities and
in rural areas. The main effects are, as described above, the reduction of traffic accidents, reduction of
environmental burden, elimination of traffic congestion, realization of effective use of urban space, etc.
ITS technology is an important element for realizing smart cities, and it is important to clearly
understand the role model of ITS service applications when developing standards to achieve these
objectives.
This document gives an important overview of the options for this objective. Considering the emerging
direction of mobility electrification, automated driving, and the direction of an environmentally
friendly society, incorporating other urban data such as traffic management into the city management
will improve the mobility of urban society. It is important to consider the creation of a common open
role model for smart city data platforms (such as the ISO 15638 series service framework). Similar
platforms will be necessary for the realization of the future mobility such as automated driving and
electrification of vehicles. A common role model will be developed for all modes of vehicle, including
public transport, general passenger vehicles and heavy vehicles. The incorporation of electronic
regulation is especially important for automated vehicles, and it is essential to incorporate it as a core
element of urban ITS.
This document describes how ITS data can be presented, interchanged, and used by smart cities. This
document does not describe smart city use cases for ITS data in any detail nor does it describe in detail
any specific ITS use cases. It is focused on the generic role model for data exchange between ITS and
smart cities.
The necessary security and data exchange protocols have now been finalized to provide a secure ITS
interface, with the approval of ISO 21177, i.e. exchange information with bi-directional protection.

5 Issues concerning data aggregation and sharing in smart city
5.1 General
ITS mobility service applications require open data aggregation of ITS data. The role and functional
definition for this service is described in this document.
1
© ISO 2023 – All rights reserved
---------------------- Page: 8 ----------------------
ISO/TR 12770:2023(E)
The ITS data aggregation role is required when combining internal data with the one externally
inputted from other sources. The combining data requires a data sharing function, privacy protection
and security controls.
5.2 Data sharing
ISO/TR 4286 describes the concept of data sharing in ITS service applications.
5.3 Open-source concept
For effective ITS data aggregation, utilising open source technology is key to success in developing
smart mobility solutions. Deploying digital twins concept and data space platform is also a part of open
source digital transformation.
Only technologies and methods standardized within an acknowledged global standards body are
appropriate for consideration. Such technologies are considered to display some track record of
sustainability and robustness to satisfy the global long-term deployment and operational nature of ITS.
5.4 Open-source API concept
Although the data API from external and sensor data is out of scope, open-source API concept is
essential for effective data sharing and utilization.
Data API to service providers is out of scope of this document.
5.5 Privacy control and security controls
Procedures regulating privacy control and security controls are usually governed by national
authorities.
5.6 Trustworthiness and data accountability
It is necessary to consider data trustworthiness and data accountability within all data flows.
6 General overview and framework
6.1 Objective
Emerging ITS service applications such as parking (including AVPS: Automated valet parking
systems), CAV (connected and automated vehicle) (including LSAD: Low speed automated driving),
Kerb operations need structured data created from smart city big data through the effective use of
AI (artificial intelligence) and support from digital infrastructure which is described in ISO/TR 7872
for secured and safety operations. And there are several independent related ongoing standardization
work items within ISO/TC 204. Therefore, there is a need of a guidebook-style technical report that
describe the basic role and functional model of the ITS data aggregation.
This will lead to digital twin operation for smart city; create digitality formed society twining real
physical world to process big data and analyse to send out data stream to real world.
In actual deployment, distributed security technology such as block chain will be introduced for
efficient and speedy transactions with secure privacy controls.
This document suggests investigating ITS as a component part of a smart city and that the ITS data can
focus on data originated by ITS components and available for sharing with other smart city services
and commercial interests.
This subclause describes a generic framework for the provision of digital infrastructure service for
cooperative telematics application services for ITS service applications.

ISO/TR 12770:2023(E)
(Clause 7 provides the general concept of operations for which this architecture is designed. Clause 6
provides a framework, role definition and summary of the architecture at a conceptual level.)
6.2 National variations
The instantiation of interoperable on-board platforms for ITS service applications with common
features is expected to vary from country to country, as will the provision of regulated, or supported,
services.
6.3 Mandatory, optional, and cooperative issues
6.3.1 No mandated requirements
This document does not impose any requirements on Nations in respect of which services for ITS
service applications countries will require, or which they will support as an option, but provides a
generic common framework architecture within which countries can achieve their own objectives in
respect of application services for ITS supported service applications in cities, and provide standardised
sets of requirements descriptions for the exchange of data to enable consistent and cost efficient
implementations where instantiated.
6.3.2 Common platform
Cooperative ITS application, in this context, is the use of a common platform to meet both regulated and
commercial service provision providing collaboration between transport systems and smart cities.
6.4 Specification of service provision
Cooperative ITS applications for ITS service applications (both commercial services and regulated
services) are specified in terms of the service provision, and not in terms of the hardware and software.
6.5 Architecture options
Architecturally, it needs to be possible for a vehicle user/OBE to use the services of different application
services. The in-vehicle system will be a vehicle original equipment specification option, inbuilt at the
time of manufacture of the vehicle, with service provider selection being a subsequent service-user
choice (much as we select an internet service provider today) or will be aftermarket equipment that has
access rights to the required data. An ITS application service will be based in the infrastructure. Other
options are possible and can be supported within the conceptual architecture. The objective of this
role model is the accessibility of the use of ITS data generated in ITS application services in smart city
application services.
7 Concept of operations
7.1 General
This clause describes the characteristics of a proposed system from the viewpoint of an individual
who will use that system. Its objective is to communicate the quantitative and qualitative system
characteristics to all stakeholders.
ISO/TR 4445 describes the roles and responsibilities of the classes and actors involved in the provision
of digital infrastructure for ITS services for ITS service applications using a secure vehicle interface.
This document recognises that there will be variations between jurisdictions, a role in ISO/TR 4445. It
does not attempt, nor recommend, homogeneity between jurisdictions, it is designed to provide common
standard features to enable equipment of common specification, that supports a standardised ‘Secure
ITS Interface’ to be used, and the common features of service provision to be able to be referenced
3
© ISO 2023 – All rights reserved
---------------------- Page: 10 ----------------------
ISO/TR 12770:2023(E)
simply by reference to an International Standard's deliverable (requiring it to specify in detail only the
additional requirements of a jurisdiction).
A ‘concept of operations’ (CONOPS) evolves from a concept and is a description of how a set of capabilities
will be employed to achieve desired objectives.
7.2 Statement of the goals and objectives of the system
The overall objective of the ITS service application in smart cities is the seamless exchange of data
between transport applications and smart city service applications.
These services are provided to meet the smart city requirements using common ‘Secure ITS interface’
communications between ITS systems (including in-vehicle systems, infrastructure-based systems,
and personal ITS stations) and smart city applications.
7.3 Strategies, tactics, policies, and constraints affecting the system
Strategies, tactics, policies, and constraints, and indeed, the services that are regulated as mandatory
or optionally supported, will vary from authority to authority.
7.4 Organisations, activities, and interactions among participants and stakeholders
The classes, attributes and key relationships are described in Clause 8, and some elevated levels
conceptual architectural detail is elaborated.

that by 2045, an extra 2 billion people will live in urban areas. The resulting concentration of population
numbers
creates various issues such as road congestion due to an increase in vehicle population and
environmental pollution due to exhaust gas and tyre erosion. These issues have been attributed to
increases in the number of delivery trucks, taxis and town centre traffic and are further exacerbated by
obstacles to the effective use of urban space due to the private ownership of cars (parking lots, street
parking).
The pressures caused by scientific advice that significant action and change of behaviour is needed to
ameliorate the adverse effects of climate change require a more environmentally friendly use of the
transport system.
It is recognized that there is also road infrastructure deterioration, a lack of provision of information on
the use of public transportation, driver shortages due to the increase in the number of elderly people and
the inconvenience of multimodal fare payments, and action to improve the situation is urgently needed.
The International Data Corporation forecasts that of the USD 81 billion that will be spent on smart city
technology in 2020, nearly a quarter will go into fixed visual surveillance, smart outdoor lighting, and
advanced public transit.
Eventually, this is likely to mean high speed trains and driverless cars. Consultancy McKinsey forecasts
that up to 15 % of passenger vehicles sold globally in 2030 will be fully automated, while revenues in the
automotive sector could nearly double to USD 6.,7 trillion thanks to shared mobility (car-sharing, e-
hailing) and data connectivity services (including apps and car software upgrades).
Changing consumer tastes are also calling for new types of infrastructure. Today’s city dwellers, for
example, increasingly shop online and expect ever faster delivery times. To meet their needs, modern
urban areas need the support of last-minute distribution centres, backed by out-of-town warehouses.
Therefore, in recent years, in Europe, studies on the development of mobility integration standards have
been active to solve urban problems. There are various movements around the world making efforts to
address these issues. In the United States, intelligent transport systems (ITS) technology is used to try to
solve these urban problems, as in the Smart City Pilot Project. Columbus, Ohio has been selected as a
smart city pilot project which is currently being designed in detail. Important key factors here are the
core architectural elements of smart cities, and urban ITS sharing of probe data (also called sensor data),
connected cars and automated driving. In addition, new issues have been recognized with the
introduction of the connected car to the real world in respect of privacy protection, the need to strengthen
security measures, big data collection and processing measures, which are becoming important
considerations.
In terms of the effective use of urban space, it is hoped that the introduction of connected cars and
automated driving can significantly reduce the requirements for urban parking lots (redistribution of
road space). If technology can eliminate congestion, the city road area usage can also be minimized and
reallocated (space utilization improvement) to improve the living environment of, and quality of life in,
the city. In addition, the environment around the road will be improved by improving enforcement (e.g.
overloaded vehicles). On the other hand, even in rural areas, it is possible to introduce automated driving
robot taxis and other shared mobility that saves labour (and is therefore more affordable) and improves
the mobility of elderly people. Formatted: Font: 11 pt

numbers
This document gives an important overview of the options for this objective. Considering the emerging
direction of mobility electrification, automated driving, and the direction of an environmentally friendly
society, incorporating other urban data such as traffic management into the city management will
improve the mobility of urban society. It is important to consider the creation of a common open role
model for smart city data platforms (such as the ISO 15638series15638 series service framework).
Similar platforms will be necessary for the realization of the future mobility such as automated driving
and electrification of vehicles. A common role model will be developed for all modes of vehicle, including
public transport, general passenger vehicles and heavy vehicles. The incorporation of electronic
regulation is especially important for automated vehicles, and it is essential to incorporate it as a core
element of urban ITS.
This document describes how ITS data can be presented, interchanged, and used by smart cities. This
document does not describe smart city use cases for ITS data in any detail nor does it describe in detail
any specific ITS use cases. It is focused on the generic role model for data exchange between ITS and
smart cities.
The necessary security and data exchange protocols have now been finalized to provide a secure ITS
interface, with the approval of ISO/TS 21177, i.e. exchange information with bi-directional protection.

5 Issues concerning data aggregation and sharing in smart city
5.1 General
ITS mobility service applications require open data aggregation of ITS data. The role and functional
definition for this service is described in this document.

© ISO 2023 – All rights reserved
---------------------- Page: 8 ----------------------
ISO/DTR 12770:2023(E)
The ITS data aggregation role is required when combining internal data with the one externally
inputted from other sources. The combining data requires a data sharing function, privacy protection
and security controls.
5.2 Data sharing
ISO/TR 4286 describes the concept of data sharing in ITS service applications.
5.3 Open-source concept
For effective ITS data aggregation, utilising open source technology is key to success in developing
smart mobility solutions. Deploying digital twins concept and data space platform is also a part of open
source digital transformation.
Only technologies and methods standardized within an acknowledged global standards body are
appropriate for consideration. Such technologies are considered to display some track record of
sustainability and robustness to satisfy the global long-term deployment and operational nature of ITS.
5.4 Open-source API concept
Although the data API from external and sensor data is out of scope, open-source API concept is
essential for effective data sharing and utilization.
Data API to service providers is out of scope of this document.
5.5 Privacy control and security controls
Procedures regulating privacy control and security controls are usually governed by national
authorities.
5.6 Trustworthiness and data accountability
It is necessary to consider data trustworthiness and data accountability within all data flows.
6 General overview and framework
6.1 Objective
Emerging ITS service applications such as parking (including AVPS: Automated valet parking
systems), CAV (connected and automated vehicle) (including LSAD: Low speed automated driving),
Kerb operations need structured data created from smart city big data through the effective use of
AI (artificial intelligence) and support from digital infrastructure which is described in ISO/TR 7872
for secured and safety operations. And there are several independent related ongoing standardization
work items within ISO/TC 204. Therefore, there is a need of a guidebook-style technical report that
describe the basic role and functional model of the ITS data aggregation.
This will lead to digital twin operation for smart city; create digitality formed society twining real
physical world to process big data and analyse to send out data stream to real world.
In actual deployment, distributed security technology such as block chain will be introduced for
efficient and speedy transactions with secure privacy controls.
This document suggests investigating ITS as a component part of a smart city and that the ITS data can
focus on data originated by ITS components and available for sharing with other smart city services
and commercial interests.
This subclause describes a generic framework for the provision of digital infrastructure service for
cooperative telematics application services for ITS service applications.

ISO/DTR 12770:2023(E)
(Clause 7 provides the general concept of operations for which this architecture is designed. Clause 6
provides a framework, role definition and summary of the architecture at a conceptual level.)
6.2 National variations
The instantiation of interoperable onboard platforms for ITS service applications with common
features is expected to vary from country to country, as will the provision of regulated, or supported,
services.
6.3 Mandatory, optional, and cooperative issues
6.3.1 No mandated requirements
This Document does not impose any requirements on Nations in respect of which services for ITS
service applications countries will require, or which they will support as an option, but provides a
generic common framework architecture within which countries can achieve their own objectives in
respect of application services for ITS supported service applications in cities, and provide standardised
sets of requirements descriptions for the exchange of data to enable consistent and cost efficient
implementations where instantiated.
6.3.2 Common platform
Cooperative ITS application, in this context, is the use of a common platform to meet both regulated and
commercial service provision providing collaboration between transport systems and smart cities.
6.4 Specification of service provision
Cooperative ITS applications for ITS service applications (both commercial services and regulated
services) are specified in terms of the service provision, and not in terms of the hardware and software.
6.5 Architecture options
Architecturally, it needs to be possible for a vehicle user/OBE to use the services of different application
services. The in-vehicle system will be a vehicle original equipment specification option, inbuilt at the
time of manufacture of the vehicle, with service provider selection being a subsequent service-user
choice (much as we select an internet service provider today) or will be aftermarket equipment that has
access rights to the required data. An ITS application service will be based in the infrastructure. Other
options are possible and can be supported within the conceptual architecture. The objective of this
role model is the accessibility of the use of ITS data generated in ITS application services in smart city
application services.
7 Concept of operations
7.1 General
This clause describes the characteristics of a proposed system from the viewpoint of an individual
who will use that system. Its objective is to communicate the quantitative and qualitative system
characteristics to all stakeholders.
ISO/TR 4445 describes the roles and responsibilities of the classes and actors involved in the provision
of digital infrastructure for ITS services for ITS service applications using a secure vehicle interface.
