INTRODUCTION
In recent years, research on the relationship between information and communication
technology (ICT) and cities, focused on imagining the future of urban planning, has been one
of the most interesting topics in the industry. Smart urban planning (SUP) for smart cities is a
relatively new concept and has not received much attention around the world. The “smartness”
of urban planning describes the intensive use of digital technologies to optimize the urban
planning process. The concept of "smart city" has been implemented and developed all over
the world. In order to construct a smart city successfully, knowing how to implement SUP for
smart cities is essential, because it is the foundation of smart urban construction. However, at
present, reaching a consensus on the overall architecture of standards of SUP for smart cities
is still challenging. The direction and user requirements of standards development is not clear,
which affects the development and application effectiveness of international standards of SUP
for smart cities.
Aimed at addressing the above problems, a systems approach to collect and analyse SUP for
smart cities use cases is put forward. The purpose of this document is to collect SUP for smart
cities use cases globally, to sort out the current situation of SUP for smart cities both
domestically and internationally, including methods, framework, ideas, and GAPS model, and
to analyse the needs of SUP for smart cities work and its stakeholders.
Understanding the use cases makes it easier to describe SUP for smart cities clusters and
highlight use cases' commonalities. All use cases that are selected have actual legitimacy.
Planning requirements are extracted from the use cases, and recommendations are given for
future standardization items related to SUP for smart cities. Collecting the use cases provides
SUP for smart cities to validate confirm the SUP for smart cities reference model and reference
architecture.
The target users for this document include the following stakeholders who have interest in SUP
for smart cities:
1) smart city planners and service providers, who can learn about SUP for smart cities needs
and how to implement the ideas;
2) government agencies and heads, who can use SUP for smart cities and implement in future
works;
3) citizens who want to have a better understanding of SUP for smart cities;
4) SUP for smart cities operators who need to understand the requirements;
5) regulators who are responsible for developing and managing SUP for smart cities and
related regulations.

4.1 General
The United Nations published 17 Sustainable Development Goals (SDGs) with an aim to
enhance world peace and prosperity, eradicate hunger and poverty, and protect people and the
planet by 2030. It calls for innovation and broad collaboration between public and private society.
The IEC SRD 63320 series mainly addresses Sustainable Development Goal 11 (Goal 11):
sustainable cities and communities.
4.2 Application area of smart urban planning
Goal 11 aims to make cities inclusive, safe, resilient and sustainable. This goal includes 11
targets which are related to smart cities: 11.1 Safe and affordable housing; 11.2 Affordable,
accessible and sustainable transport systems; 11.3 Inclusive and sustainable urbanization;
11.4 Protect and safeguard the world’s cultural and natural heritage; 11.5 Reduce the adverse

5 Approach for use case collection and analysis
The IEC SRD 63320 series adopts a top-down approach to generate and collect the use case
of smart urban planning, as illustrated in Figure 1.

Figure 1 – Approach for use case collection and analysis
Firstly, a thorough study of smart urban planning is needed at the beginning of use case
collection and analysis. The purposes of the work of SUP high-level system study include to
identify sub-systems, to identify basic stakeholder needs, and to develop SUP a use case
template for sub-system based on IEC TR 62559-1 and IEC 62559-2. The template of smart
urban planning application area survey table is found in Annex A.
Secondly, generate and collect a list of use case about smart urban planning following the use
case template. Develop a list of significant user stories based on the collected use case. In
each corresponding area, one user story is generated for one specific stakeholder. Each user
story follows the same template, which includes one stakeholder (as a specific type of user), a
specific situation (when), a goal (I want to), and a reason (so that).
Thirdly, break down each element of the use case, including stakeholders, user stories, etc.,
and establish the use case database of smart urban planning.
Lastly, conduct an integrative analysis based on the use case database, and identify the
standard gaps for smart urban planning and requirements for a family of smart urban planning
standards.
This document focuses on the first and second steps of the work approach.
6 Use case stratification
6.1 General
IEC TR 62559-1 and IEC 62559-2 give a detailed definition and classification about business
case, high-level use case and specialized use case. The IEC SRD 63320 series will consider
the content and stratification of smart urban planning to correspond to three levels of use case.
6.2 Business case
A business case comes into being when something unites different actors (stakeholders) with
their own business goals.
For smart urban planning, business cases can be identified according to the step of urban
planning. There is a total of six business cases in smart urban planning, corresponding to the
six steps of urban planning system, namely preparatory work, data collection and analysis,
strategy formulation, plan review and approval, plan implementation, and monitoring and
assessment.
6.3 High-level use case
High-level use case describes a general requirement, idea or concept independently from a
specific technical realization like an architectural solution. High-level use cases can be derived
from business cases through model transformation, in which business actors involved in
business cases are transformed into logical actors that are interpreted as logical entities
involved in a particular high-level use case.

– 12 – IEC SRD 63320-1:2023 © IEC 2023
For smart urban planning, the application area of smart urban planning is regarded as the high-
level use case. The process of breaking down smart urban planning into different high-level use
cases is a key part of high-level analysis.
6.4 Specialized use case of SUP
High-level use case usually describes an innovative, abstract function but the actual technical
implementation is not dealt with. On this basis, specialized use cases can be developed and
explain a tangible elaboration of the technical aspects.
7 High-level analysis of smart urban planning
7.1 General
Smart urban planning is the application of digital technology on the basis of urban planning.
Therefore, model of smart urban planning is adjusted and transformed on the basis of model of
urban planning.
7.2 Steps of urban planning
7.2.1 General
Urban planning is a systematic, formal, standardized work cyclic process. It includes pre-
planning, planning and post-planning stages. These three stages are then further broken down
into six steps, including preparatory work in the pre-planning stage, data collection and analysis,
strategy formulation, and plan review and approval in the planning stage, implementation and
monitoring and assessment in the post-planning stage.
1) Pre-planning stage. The first, and in some respects, the most important stage is ‘pre-
planning,’ or preparing to plan. This stage diagnoses the planning area. Once local officials
and the public understand the purpose, values and benefits of planning and agree on a
process to prepare the plan, the following steps become much easier.
2) Planning stage. The second stage – ‘planning’ – consists of three major steps. These include
data collection and analysis, strategy formulation, and plan review and approval. The
planning stage in Figure 2 shows several positive feedback loops. This is meant to illustrate
that planning does not always proceed in a linear fashion. At times, the planning department
can need to revisit or reorder steps to respond to new data or unexpected reactions to a
proposal. Some flexibility should be built into the process to accommodate these unknowns.
Depending on how planners choose to organize the planning process, a given community
may also have more or fewer steps than what is shown.
3) Post-planning stage. The third stage is ‘post-planning’, which consists of plan
implementation, monitoring and post-implementation evaluation.
The urban planning system applies to all kinds of urban planning, including master planning,
new and pre-existing land-use planning, urban revitalization, economic development planning,
environmental planning, infrastructure planning, regulatory planning and so on.

Figure 2 – The steps of urban planning
As shown in Figure 2, the steps of urban planning are a whole life cycle, from pre-planning
stage to planning stage to post-planning stage, which includes six work steps. The conclusions
of the last step, monitoring and assessment, usually become the basic material for a new urban
planning project to start. The work achievements of each step will become the input for the next
step through the arrow. In the strategy formulation step, it will return to the previous step to
collect and analyse new data according to the requirements of new strategies. In the plan review
and approval step, it will return to the previous step to modify the strategies if the plan review
does not pass.
7.2.2 Step 1 – Preparatory work
The goals of preparatory work of urban planning are to identify the planning problems and
objectives, available resources within the planning area, and stakeholders involved. The
activities of this step are following.
1) Inventory existing urban planning, studies and tools.
2) Determine the planning purpose, capacity and readiness of the area.
3) Identify potential planning participants and stakeholders and agree with them on the urban
planning purposes.
7.2.3 Step 2 – Data collection and analysis
Data collection uses various methods or technologies to collect city information needed by
urban planning. The information collected is used for data analysis and planning compilation.
Data analysis mines data value and planning suggestions from various items of urban
information with the help of information analysis tools and technologies. The activities of this
step are the following.
1) Urban information collection, storage and quality check.
2) Urban data analysis and interpretation.

– 14 – IEC SRD 63320-1:2023 © IEC 2023
7.2.4 Step 3 – Strategy formulation
Based on the issues reflected in data analysis and public opinion, and the development vision
shared by relevant stakeholders, identify the potential planning strategies within the planning
area from multiple aspects. Furthermore, this step also shall describe elements clearly involved
during strategies implementation, including timeline, participants, investment fund, etc., to
support the implementation of strategies. The activities of this step are the following.
1) Identify potential plan implementation strategies to satisfy goals and objectives.
2) Evaluate impacts of alternative strategies and select preferred options.
3) Recommend specific plan implementation policies, programmes, actions and tools.
4) Describe timeline and parties responsible for plan implementation.
7.2.5 Step 4 – Plan review and approval
Plan review and approval is the qualitative or quantitative review of planning results by planning
decision-making departments of third-party institutions to make planning results in line with
relevant policy requirements and demands of all participants. The activities of this step are the
following.
1) Review the urban planning results to meet the requirements of laws, policies and published
plans.
2) Present the plan for public and officials to review.
3) Make changes to the plan to resolve inconsistencies or address issues of concern to local
officials and the public.
4) Take formal action to approve and publish the urban planning.
7.2.6 Step 5 – Plan implementation
Implementation supervises whether the implementation meets the planning requirements in the
process of planning implementation. The activities of this step are the following.
1) Adopt a specific course of action to implement the plan.
2) Supervise the implementation of the project to meet the targets or achievements of the
planning.
7.2.7 Step 6 – Monitoring and assessment
Monitoring and assessment evaluates the results of the planning implementation after the
completion of implementation. It compares the gap between planning goals and actual situation.
The conclusions of planning evaluation will provide a basis for new planning. The activities of
this step are following.
1) Monitor progress towards achieving stated goals, objectives and indicators.
2) Review and revise plan according to schedule stated in the plan or in response to changing

7.3 Transformation of smart urban planning
Based on the steps of urban planning, the model of smart urban planning shall further interpret
the planning process, activities and specific work with the help of digital and intelligent
technologies.
The IEC 63320 series builds an innovative and sustainable model to drive the adoption of smart
urban planning. It provides guidance for the working sequence of six critical steps of smart
urban planning from preparatory work to monitoring and assessment, see Figure 3. Each step
contains a number of planning activities as smart urban planning solutions supported by specific
technologies, including big data, CIM, IoT, GIS, cloud, AI and so on. Specialized use case
analysis shall follow such a systems model, building on the foundation of specialized use case
collection.

8 Analysis conclusions of smart urban planning
8.1 General
Smart urban planning refers to a digital and intelligent urban planning system, in which
advanced technologies are used in all aspects, from pre-planning phase to planning phase to
post-planning phase. Urban planning is a complex system, involving a variety of urban planning
types and complex workflow. Therefore, there are many options for digital and intelligent
technologies to enhance the efficiency and effectiveness of urban planning.
8.2 Model of smart urban planning
8.2.1 General
The description of the SUP for smart cities architecture model is as follows.
Smart urban planning refers to optimizing the workflow and improving the accuracy and
effectiveness of smart urban planning based on use of AI, big data, CIM, IoT, GIS, cloud and
other technologies in six smart urban planning steps (business use cases), see Figure 4. Smart
urban planning can help smart city planners, public sectors, regulators and others to formulate
more scientific development strategies in various fields of smart cities, such as ICT
infrastructure, smart transportation, smart municipality, smart community and other fields. It can
help cities achieve sustainable development goals.

8.2.2 Preparatory work
Preparatory work relies on the smart platform to assist planners and government agencies to
organize planning tools, and try to gain recognition from more stakeholders. The technologies
involved include database technology, knowledge graph technology, interactive technology and
other intelligent technologies or technology packages.
The business use case of preparatory work includes two application areas: planning tool
inventory and stakeholder identification, see Figure 5. The former is the most fundamental
application area in the business use case of preparatory work, which aims to integrate all urban
planning, studies and tools. The latter is an ensuing application area. With the support of
inventory planning
