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.

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
— 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.
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. Deploy
