ISO/TR 7872:2022(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 civilizations develop and congregate around the areas where employment

opportunity most arises. Societies develop more innovatively and more rapidly in cities, adding to

their attraction. Finally, cities present better entertainment opportunities. These points all add to their

attraction and popularity, hence the continuing trend. It has recently been forecast that by 2045, an

[4]

additional 2 billion people will live in urban areas. Due to the concentration of the population that

this causes, various issues arise, such as road congestion due to increases in vehicle population and

environmental pollution due to exhaust gas and tyre erosion. This has been attributed to increases in

the amount of delivery trucks, taxis and town centre traffic and is further exacerbated by obstacles to

effective use of urban space due to private ownership of cars (parking lots, street parking).

In line with scientific advice that significant action and change of behaviour is needed to ameliorate

the adverse effects of climate change, more environmentally-friendly use of the transport system is

required.

It is also recognized that within cities, there is a general deterioration in road infrastructure, lack of

provision of information on the use of public transportation, driver shortages (due to an increase in

the number of elderly people) and inconvenience of multimodal fare payments. Action to improve this

situation is urgently needed.

Therefore, in recent years, in Europe, studies on the development of mobility integration standards

have been active in solving urban problems. There are also various movements around the world

making efforts to address such issues. In the United States, for example, intelligent transport system

(ITS) technology is used to try to solve urban problems in the Smart City Pilot Project. 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 regarding privacy protection,

the need to strengthen security measures, big data collection and processing measures, which are

becoming important considerations.

In terms of 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, city road area usage can also be minimized or

reallocated (space utilization improvement) to improve the living environment and quality of life in the

city. In addition, the environment around the road will be improved by improving enforcement (e.g.

overloaded vehicles). It is possible, even in rural areas, 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, the following points will need to be achieved:

— cooperation in the harmonization of International Standards and other industry standards;

— recognition of the significance of international standardization (for example, in reducing

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.

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.

ISO/TR 4445 is already an important resource for this objective, providing consideration of the emerging

direction of mobility electrification, automated driving and the direction of an environmentally friendly

society, whilst also incorporating other urban data such as traffic management into city management

within the context of improving the mobility of urban society.

This document, ISO/TR 7872, describes how ITS sensor data can be integrated into a valuable data

cluster presented on map data, so that ITS service providers can provide services such as automated

driving, parking, kerb operations, etc.

This document does not describe smart city use cases for ITS data in detail, nor does it describe in detail

any specific ITS use-cases; it is instead focussed on the generic role model for digital infrastructure

service.

5 General overview and framework
5.1 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) and kerb

operations require infrastructure supports for secured and safety operations. Several ongoing

standardization work items exist within ISO/TC 204, including:
— high definition (HD) maps,
— management for electronic traffic regulations (METR), and
— graphic data dictionary (GDD).

There is a need for the creation of a document describing how these standardization items fit into

a prospected digital infrastructure service role and functional model for smart city ITS service

applications.

This will lead to a digital twin operation for smart cities: creation of a digitality formed society

connecting real (physical world) society to processing and analysing big data and sending out a data

stream to the real world.

In actual deployment, distributed security technology such as block chain will be introduced for

efficient and speedy transactions.

This document suggests investigating ITS as a component of a smart city and that the ITS data can

focus on data originating from ITS components and available for sharing with other smart city services

and commercial interests.

This clause describes a generic framework for the provision of digital infrastructure services for

cooperative telematics application services for ITS service applications.

(Clause 6 provides the general concept of operations for which this architecture is designed. Clause 7

provides a framework, role definition and summary of the architecture at a conceptual level.)

5.2 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.
5.3 Mandatory, optional, and cooperative issues

5.3.1 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 can provide

standardized sets of requirements descriptions for the exchange of data to enable consistent and cost

efficient implementations where instantiated.

5.3.2 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.
5.4 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.

5.5 Architecture options

Architecturally, it needs to be possible for a vehicle user/on-board equipment (OBE) to use the services

of different application services. The in-vehicle system can be a vehicle-original equipment specification

option, in-built at the time of manufacture of the vehicle, with the service provider selection being a

subsequent service-user choice. Alternatively, it can be after-market 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.

6 Concept of operations
6.1 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 recognizes that there will be variations between jurisdictions, a role in ISO/TR 4445. It

does not attempt, nor recommend, homogeneity between jurisdictions. It is simply designed to provide

common standard features to enable equipment of common specification, that supports a standardized

‘Secure ITS Interface’, to be used, and to enable the common features of service provision to be able to

be referenced simply by reference to an ISO deliverable (requiring detailed specification of only the

additional requirements of a jurisdiction).

A ‘concept of operations’ (CONOPS) generally evolves from a concept and is a description of how a set of

capabilities will be employed to achieve desired objectives.
6.2 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.
6.3 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 jurisdiction to jurisdiction. Clause 7 provides detail of the options

of such aspects.

6.4 Organizations, activities and interactions among participants and stakeholders

The classes, attributes and key relationships are described in Clause 7. High-level conceptual

architectural detail is elaborated in Clause 8.
6.5 Clear statement of responsibilities and authorities delegated

Clause 6 describes the high-level options and issues. The actors, their responsibilities and authorities

are described in Clause 7.
6.6 Operational processes for the system

The following description of operational processes is at a high abstracted level (above that of any

application service). Specific services will have additional requirements not described herein.

6.6.1 Service requirements definition

A smart city application service provides a service (a benefit that a service user receives or a duty

that a service user provides) to a service user using exchanges of data, in this case using a secure ITS

interface. Smart cities can also use other communications means appropriate to the context of their

use. The interface will be wired or wireless, but is likely to be the latter, in which case the latency of the

system will limit the ability to provide/capabilities of the application service.

ISO/TR 7872:2022(E)

An ITS application service provides an ITS service (a benefit that a service user receives or a duty that

a user provides) to a service user using a secure ITS interface. The interface will be wired or wireless,

but is likely to be the latter, in which case the latency of the system will limit the ability to provide/

capabilities of the application service.

Wireless communications between a vehicle and its original equipment manufacturer (OEM), commonly

known as "ExVe" (extended vehicle) are separate and complementary to, and out of the scope of, this

document.
6.7 Appointment of an approval authority (regulatory)

This document is based on the premise that a smart city will develop its own regulation base (in consort

with national government and other smart cities). The term used in this document to describe this

organization and its regulation base is the ‘jurisdiction’, and this body creates or appoints an authority

to approve and audit the ‘process’. The ‘process’ in this context is a smart city application service. The

assumption is made that there will be some form of approval process to control smart city application

services and their cybersecurity (at the least to protect privacy and avoid fraud, and to minimize risks

of terrorism or other disruption). The structure of that authority is a matter for the jurisdiction, and it

will be a separate appointed organization, or a department of the jurisdiction. Within the context of this

document, it is the actor ‘role’ of ‘approval authority’ that is important, not its structure, ownership or

business model.
An approval authority (regulator
