Application and Prospect of Artificial Intelligence Technology in Low-Carbon Cities—From the Perspective of Urban Planning Content and Process

In the era of digital transformation, artificial intelligence (AI) technology—one of the swiftest growing emerging technologies—when integrated with urban planning, can introduce innovative approaches for low-carbon city development and foster the attainment of dual carbon objectives: carbon neutrality and peak carbon emissions. Current research predominantly investigates the influence and alterations of emerging technologies on urban elements, yet it overlooks a comprehensive examination of the applicable procedures of these technologies and their potential synergy with urban planning. Consequently, this study employs a systematic literature review to delve into the application of AI in sectors such as architecture, transportation, land use, and green space development. It categorizes the specific impact processes into monitoring, identification, simulation, and prediction. By offering an exhaustive analysis of urban planning’s content and methodology, this paper elucidates the role of AI technology in the creation of low-carbon cities. The study found that: (1) Due to the varying degrees of application and integration with professional technologies in different fields, the current research focuses more on architecture, land use, and transportation. (2) Combining the four steps of urban planning, artificial intelligence can be divided into monitoring, recognition, simulation, and prediction types, each with its own characteristics. (3) Overall, AI technology is mainly applied in the identification and simulation of architecture, transportation, and land use. (4) There is still room for improvement in the application of AI technology in waste emissions and other algorithms.

Fostering Gender Transformative Cities around the World

In the context of rapid urbanisation and the effects of climate change and conflicts, social inclusion and stakeholder engagements remain a low priority for most decision-makers in shaping the future of cities. The urban development initiative Her City intends to mainstream gender and age perspectives in urban planning and design decision-making processes. Her City offers a toolbox for municipal professionals, urban actors, and local decision-makers to involve girls and young women in urban planning and design processes and challenge exclusionary practices and social inequalities. This viewpoint asserts that integrating girls' perspectives leads to more responsive urban planning and the creation of inclusive and economically viable public spaces across the world. Applying an intersectional approach to urban planning, in a multitude of urban settings with different social, cultural, political and economic prerequisites, have proven to be an efficient shortcut to sustainable cities, Additionally, the initiative's success is underscored by its alignment with the Sustainable Development Goals (SDGs), delivering resilient cities for all. This viewpoint presents lessons learned from the application of Her City in Peru, Jamaica, Mozambique, Uganda, Palestine, Thailand, and Italy. These localised projects in various regions demonstrate how Her City can deliver tangible outcomes, such as the revitalisation of public spaces, community empowerment, and the promotion of gender equality, while fostering social cohesion, economic empowerment, and environmental sustainability. By championing gender-responsive urban development, Her City offers a blueprint for creating inclusive, resilient, and sustainable cities globally.

Urban Development Together with Girls and Young Women

Public spaces are crucial to everyday life, providing sites for community interaction, mobility, and recreation. Traditionally, however, urban planning has been shaped by a gendered perspective that privileges masculine assumptions that overlook intersectional needs and reinforce societal inequalities for women and girls. This special issue, ‘Let Her Guide You’, developed in partnership with UN-Habitat as part of the Her City initiative, underscores the imperative of incorporating gender and youth perspectives into urban planning and design. The Her City Initiative, a collaboration between UN-Habitat and the Shared City Foundation, advances this goal by equipping urban actors worldwide with tools to integrate the perspectives of girls and young women into urban development. Launched in 2021, the Her City Toolbox has supported over 350 independent initiatives with registered users in 120 countries, demonstrating its effectiveness in fostering inclusive urban environments. This special issue features papers by young academic scholars selected from the Her City Master students alumni network, including case studies of feminist planning from Heerlen (The Netherlands), Nairobi (Kenya), Stockholm (Sweden), and Weimar (Germany). It also includes a diverse range of invited viewpoints advocating for collaborative approaches to urban development together with girls and young women, complemented by illustrative case studies from around the globe, including Belgium, Iran, Italy, Jamaica, Mozambique, Palestine, Peru, South Africa, Sweden, Thailand, Uganda, and the United Kingdom. By centring gender and youth perspectives in the urban planning process, this special issue highlights the potential to transform public spaces into more equitable, engaging, and sustainable environments. It calls on city makers, researchers, and community leaders to ensure that contemporary cities are designed with and for everyone.

Modeling Population Mobility Flows: A Hybrid Approach Integrating a Gravity Model and Machine Learning

Population mobility between cities significantly affects traffic congestion, disease spread, and societal well-being. As globalization and urbanization accelerate, understanding the dynamics of population mobility becomes increasingly important. Traditional population migration models reveal the factors influencing migration, while machine learning methods provide effective tools for creating data-driven models to handle the nonlinear relationships between origin and destination characteristics and migration. To deepen the understanding of population mobility issues, this study presents GraviGBM, an expandable population mobility simulation model that combines the gravity model with machine learning, significantly enhancing simulation accuracy. By employing SHAPs (SHapley Additive exPlanations), we interpret the modeling results and explore the relationship between urban characteristics and population migration. Additionally, this study includes a case analysis of COVID-19, extending the model’s application during public health emergencies and evaluating the contribution of model variables in this context. The results show that GraviGBM performs exceptionally well in simulating inter-city population migration, with an RMSE of 4.28, far lower than the RMSE of the gravity model (45.32). This research indicates that distance emerged as the primary factor affecting mobility before the pandemic, with economic factors and population also playing significant roles. During the pandemic, distance remained dominant, but the significance of short distances gained importance. Pandemic-related indicators became prominent, while economics, population density, and transportation substantially lost their influence. A city-to-city flow analysis shows that when population sizes are comparable, economic factors prevail, but when economic profiles match, living conditions dictate migration. During the pandemic, residents from hard-hit areas moved to more distant cities, seeking normalcy. This research offers a comprehensive perspective on population mobility, yielding valuable insights for future urban planning, pandemic response, and decision-making processes.

Large language model as parking planning agent in the context of mixed period of autonomous vehicles and Human-Driven vehicles

Autonomous vehicles (AVs) are anticipated to revolutionize future transportation, necessitating updates to traffic infrastructure, particularly parking facilities, due to the unique characteristics of AVs compared to Human-Driven Vehicles (HDVs). During the transition period in which AVs and HDVs coexist, adaptable infrastructure is essential to accommodate both vehicle types. Traditional research, typically reliant on complex mathematical models and simulations, faces challenges in adapting to diverse urban settings, requiring substantial time and resources. To address these challenges, a government-level framework was developed, enabling urban planners to quickly and accurately evaluate and optimize existing parking facilities for future AV and HDV coexistence scenarios. The framework integrates a Large Language Model (LLM) to enhance flexibility and efficiency in parking planning throughout the transitional period. Structured guidance is incorporated to enhance decision-making precision and reduce LLM hallucination risks. The flexibility, robustness, and accuracy of the framework were validated through step-by-step and end-to-end testing using real-world datasets. Specifically, the framework achieved 91.1 % comprehensiveness and 70.2 % consistency in Indicator Selection Module testing, a 68.9 % success rate in the Single Indicator Calculation Module, and a 66.7 % success rate in end-to-end testing, demonstrating its practical value in supporting cities during AV integration. Finally, the success rates of different LLM agent modules were further explored, along with a comparison of multiple LLMs and an analysis of key issues related to LLM trustworthiness in urban planning applications. The research highlights the potential of LLMs in advancing urban planning processes and optimizing existing infrastructure, contributing to smarter and more adaptable urban environments.

A Geodatabase Design for the Development of a Digital Twin for Urban Environments: A Case Study from Turin, Italy

Abstract. 3D City models are essential for urban planning, accurately visualizing, analyzing, and simulating urban environments. They find applications in various fields like AEC (Architecture and Construction), urban and transportation planning, development and conservation processes, energy systems monitoring, and many more. Extensive datasets for the 3D City Models need to be organized following international standards to make them reusable and sharable for different stakeholders. Designing a Geodatabase (GeoDB) for a 3D city model is crucial for data management as it is helpful in the streamlined visualization and analysis of the city's features and relations among its objects. Over the years, 3D city models have evolved into Urban Digital Twins, offering dynamic real-time simulations of cities and even better management and analysis of urban processes. This transition from 3D city models to UDTs enhances decision-making by providing detailed insights into the dynamics of urban systems, enabling better urban management and planning. This research concentrates on building a GeoDB to support the UDT. The paper discusses the data acquisition, processing, and integration methodologies.Additionally, it highlights the significance of utilizing advanced remote sensing technologies such as aerial LiDAR and aerial photogrammetry to enhance the digital twin’s quality and richness in detail. The semantics of the built environment datasets are clarified and strictly defined for the most important UDT features, such as buildings, roads, trees, and other features. This will ensure everyone can interpret the data similarly, leading to better analysis and decision-making.

URBANISMO, DIGNIDADE E DIREITO À CIDADE, NA ERA DAS PPPs DOS GRANDES PROJETOS URBANOS

This work is the result of a research for the theoretical framework of a doctoral thesis, developed in the Graduate Program in Architecture and Urbanism of the Federal University of Bahia, in order to promote a discussion on the Right to the City. An exploratory research is carried out based on a bibliographic survey, which includes scientific articles and books that deal with the theme under discussion here. The discussion has been taking place for decades, since the period of struggle for Urban Reform in Brazil. The objective is to discuss the instruments of urban policy, relating the issue of the Right to the City and the role of the State as a mediator of a process where there are several actors, but which, together with the private sector, social movements and civil society organizations, constitutes one of the main agents of (re)production of urban space. It seeks to discuss the role of the State, through such instruments of urban policy, as well as their effectiveness and the processes of urban planning and management, in the sense of the social function of urban property, in the face of large urban projects, often gestated with PPPs.

Exploring the regional cooling efficiency of urban residential vegetation using scenario simulation

The study of the cooling efficiency of vegetation in urban residential areas at a micro-scale is important for improving the thermal environment of those areas. The quantitative analysis of the effect of the layout of different building patterns on the cooling efficiency of green space is particularly crucial. This study takes a typical residential area with a row-column arrangement in Jiangning District, Nanjing City, Jiangsu Province, China, as the research object. Using the ENVI-MET model used for numerical simulation, 15 simulation scenarios were designed based on building orientation, height, and density. The research proposes the methodology of the regional cooling efficiency (RCE) of urban residential vegetation, reveals the daily variation characteristics of the RCE of vegetation in a residential area, and analyzes the factors influencing of regional cooling efficiency. The results showed that the daily variation in RCE for vegetation in the residential area exhibited a single-peak trend. The minimum and maximum RCE values appeared at 6:00 and 14:00, respectively. The average air temperature and building density in the residential area had a significant positive correlation with RCE, while average relative humidity had a negative correlation. Average wind speed, average building height, and average sky view factor showed nonlinear correlations with RCE, and the importance ranking of each factor's effect on RCE was air temperature > relative humidity > building density > wind speed > building height > sky view factor. This study will provide theoretical support for improving the thermal environment in urban residential areas during the urban planning process.

Towards healthier places: understanding local authority implementation of health impact assessments in urban planning projects in England

ABSTRACT Health Impact Assessment is a tool increasingly used by local authorities in the urban planning process to support the delivery of healthy places. However, there is a lack of evidence on the use of health impact assessments, including how they fit into planning decision-making processes. This paper reports on a qualitative study with nine participants in public and private sectors involved in the health impact assessment process in England. Using the language of policy theory, a model of how health impact assessments work to promote health in urban planning projects is proposed: in part by forcing change from developers through regulation, but more so by persuading them to make healthier developments voluntarily through a process of collaboration and dialogue. This model can help stakeholders involved in health impact assessments understand and manage the process more effectively. Findings also highlight enablers and barriers of effective practice which form the basis of recommendations for local authorities implementing Health Impact Assessment.

Sunlight exposure conditions for buildings in European localities

Sunlight exposure represents one of key parameters of indoor climate comfort, especially for residential buildings, schools and care homes. It depends on the sunlight time in specific design situations like a locality, building type, window size, position and orientation. A practical evaluation of sunlight access into buildings is based on a standard methodology in EN 17037. The methodology based on parameters of minimum solar altitude is specified for given geographical locality and time of the sunlight exposure evaluation. The aim of this study is to compare how the sunlight exposure is changed in European regions. The evaluation is based on the standard limitations to specify potentials for the building insolation assessments in different geographical localities. Research value of the study deals with the general overview of the sunlight potential of building insolation in different European climatic regions. It can be important for building design and urban planning process in those localities. The research is focused on determining the minimum solar altitude for 33 capitals and for all days from 1st February to 21st March specified by the standard to ensure the required minimum insolation time.

Cognitive Urban Planning Enhancing Decision-Making in Local Governments.

According to the United Nations (UN), a “continuous, participatory, and inclusive urban planning process should be the starting point and framework for improving population living conditions,” and this research emerges from examining trends in smart cities. It explores the impact of collective intelligence, geographical information systems, and cognitive systems as a way of supporting the decision-making of local governments (municipalities) to face the challenges announced by the UN in the Urban Agenda 2017. This methodology employs an exploratory approach using the participatory action research method. The model was tested in three municipalities in Ecuador using a technological and collaborative platform called Cognitive Urban Planning (PUC). The results highlighted improvements in the decision-making process in urban planning, since the interactive participation processes through the PUC allowed for the suggestion of a group of strategies for an emerging neighborhood plan developed with the citizens working together in the municipality in real-time. In conclusion, the effects of the decision-making plan could be applied to improve and enhance community participation through city co-creation, supporting the decision-making process of municipalities in a way that promotes inclusive urban planning and stakeholders' awareness, as the recommended plans are supported by the desires and needs raised by citizens.

ТЕОРЕТИЧНИЙ АНАЛІЗ ПОНЯТТЯ РЕГУЛЯТОРНА ПОЛІТИКА У ПЛАНУВАННІ ТА ЗАБУДОВІ МІСТА: ОСНОВНІ ПІДХОДИ ТА СУЧАСНІ ТЕНДЕНЦІЇ

Regulatory policy in the field of urban planning and development is a key element of public administration aimed at ensuring economic stability, social welfare and sustainable development. In the conditions of globalization and intensive technological progress, effective regulation of urban planning processes is becoming more and more important for solving modern challenges. The purpose of this study is to carry out a theoretical analysis of the concept of regulatory policy in urban planning and development, to study the main approaches to its implementation, as well as to determine modern trends and opportunities for adapting international experience for Ukraine. In particular, the research aims to identify effective models of regulatory policy that can be integrated into national legislation and practice to improve the management of urban development. The research uses a comprehensive approach, which includes the analysis of scientific publications, comparative analysis of regulatory policies of different countries, methods of critical literature review and data synthesis. Special attention is paid to the experience of countries such as the USA, Germany and Singapore, where various approaches to the regulation of urban planning processes are used. The analysis showed that regulatory policy in urban planning and development is a multifaceted phenomenon, which includes such basic approaches as zoning, strategic spatial planning, energy efficiency, integration of transport infrastructure and active involvement of the public in the decision‒ making process. Modern trends in regulatory policy have been identified, including innovative approaches to planning, the use of digital technologies, an emphasis on sustainable development and environmental safety. A comparative analysis of the regulatory policies of the USA, Germany, and Singapore made it possible to identify effective models that can be adapted to the conditions of Ukraine. The study confirmed that an effective regulatory policy is an important prerequisite for sustainable economic development, social stability and protection of citizens' rights. Further research should focus on the integration of digital technologies into regulatory processes, improvement of control and monitoring mechanisms, which will contribute to the sustainable development of cities in Ukraine.

Tourism in smart villages as an enhancement of rural areas

The purpose of this work is to verify whether Italian smart villages are attractive on a tourist level. This article has the task of analyzing and highlighting the health status of rural villages and checking which and how many of them have evolved toward a sustainable rural village concept, defined in the literature by the name smart village. The study was conducted through the analysis of the projects applied within the two smart villages under study. The two villages analyzed focus on future-oriented development and identify already integrated urban areas as a test bed, capable of attracting the population, workers, and tourists. Both villages have common objectives such as, for example, the transformation from rural villages into smart villages, overcoming the state of depopulation, making them attractive on a tourist level, and pursuing urban development strategies, guaranteeing territorial sustainability. The urban planning process and energy policies are integrated with the Smart Village policies, whose meeting point and strength are represented by the technology applied to the city. The method brings to both experiences multiple points of advantage dictated by the fact that the methodology allows all interested parties of citizens to actively participate in the political life and not only of the city. The successful application of transformation policies in these cities can be used as a future test bed to enable other cities to develop and evolve from classic rural villages to smart villages.

Vivid London: Assessing the resilience of urban vibrancy during the COVID-19 pandemic using social media data

Since COVID-19, the focus on urban resilience has intensified, particularly on cities' ability to adapt and recover while maintaining essential functions and liveability; however, few studies have examined the resilience of urban vibrancy during such health crises. This study investigates urban vibrancy resilience in Inner London during the COVID-19 pandemic using multi-sourced social media data (geo-tagged Twitter and Flickr). We propose an analytical framework based on space-time permutation scan statistics (STPSS) to identify spatiotemporal urban areas of interest (ST-AOIs), examining their spatial, temporal, and contextual characteristics. Our findings show that central neighbourhoods with transport hubs, educational and healthcare facilities, eateries, and financial centres exhibit greater resilience. These areas adapt by shifting active periods in response to disruptions. Additionally, we assess the varying resilience capacities of different types of points of interest. This research provides actionable insights for urban planners and policymakers by demonstrating how identifying characteristics of robust urban vibrancy can contribute to the resilience of cities and communities, particularly under normal conditions after COVID-19. The findings offer concrete strategies for integrating social media data into urban planning processes, enabling more responsive and adaptive governance that meets the dynamic needs of urban populations.

Climate change vulnerability assessment in the new urban planning process in Tanzania

Climate change vulnerability assessment is an essential tool for identifying regions that are most susceptible to the impacts of climate change and designing effective adaptation actions that can reduce vulnerability and enhance long-term resilience of these regions. This study explored a framework for climate change vulnerability assessment in the new urban planning process in Jangwani Ward, Tanzania. Specifically, taking flood as an example, this study highlighted the steps and methods for climate change vulnerability assessment in the new urban planning process. In the study area, 95 households were selected and interviewed through purposeful sampling. Additionally, 10 respondents (4 females and 6 males) were interviewed for Focus Group Discussion (FGD), and 3 respondents (1 female and 2 males) were selected for Key Informant Interviews (KII) at the Ministry of Lands, Housing and Human Settlements Development. This study indicated that climate change vulnerability assessment framework involves the assessment of climatic hazards, risk elements, and adaptive capacity, and the determination of vulnerability levels. The average hazard risk rating of flood was 2.3. Socioeconomic and livelihood activities and physical infrastructures both had the average risk element rating of 3.0, and ecosystems had the average risk element rating of 2.9. Adaptive capacity ratings of knowledge, technology, economy or finance, and institution were 1.6, 1.9, 1.4, and 2.2, respectively. The vulnerability levels of socioeconomic and livelihood activities and physical infrastructure were very high (4.0). Ecosystems had a high vulnerability level (3.8) to flood. The very high vulnerability level of socioeconomic and livelihood activities was driven by high exposure and sensitivity to risk elements and low adaptive capacity. The study recommends adoption of the new urban planning process including preparation, planning, implementation, and monitoring-evaluation-review phases that integrates climate change vulnerability assessment in all phases.

Areas explored include green gentrification, climate change impacts, health and well-being effects, environmental justice, and associated public policies. The study highlights the need for policies that balance environmental improvement with social protection, and underlines the importance of including local communities in urban planning processes to prevent displacement and increase social equity. This interdisciplinary approach provides valuable insights to understand the complexity of gentrification and its multiple dimensions in an urban and environmental context

A Review of Urban Planning Approaches to Reduce Air Pollution Exposures.

With only 12% of the human population living in cities meeting the air quality standards set by the WHO guidelines, there is a critical need for coordinated strategies to meet the requirements of a healthy society. One pivotal mechanism for addressing societal expectations on air pollution and human health is to employ strategic modeling within the urban planning process. This review synthesizes research to inform coordinated strategies for a healthy society. Through strategic modeling in urban planning, we seek to uncover integrated solutions that mitigate air pollution, enhance public health, and create sustainable urban environments. Successful urban planning can help reduce air pollution by optimizing city design with regard to transportation systems. As one specific example, ventilation corridors i.e. aim to introduce natural wind into urban areas to improve thermal comfort and air quality, and they can be effective if well-designed and managed. However, physical barriers such as sound walls and vegetation must be carefully selected following design criteria with significant trade-offs that must be modeled quantitatively. These tradeoffs often involve balancing effectiveness, cost, aesthetics, and environmental impact. For instance, sound walls are highly effective at reducing noise, provide immediate impact, and are long-lasting. However, they are expensive to construct, visually unappealing, and may block views and sunlight. To address the costly issue of sound walls, a potential solution is implementing vegetation with a high leaf area index or leaf area density. This alternative is also an effective method for air pollution reduction with varying land-use potential. Ultimately, emission regulations are a key aspect of all such considerations. Given the broad range of developments, concerns, and considerations spanning city management, ventilation corridors, physical barriers, and transportation planning, this review aims to summarize the effect of a range of urban planning methods on air pollution considerations.

Sustainability of the Urban System Planning in Shu City, Kazakhstan: An Evaluation through Residents’ Perception

It is important to consider the local people’s evaluation in increasing the effectiveness of the sustainable planning process in urban system planning. In this work, the sustainability of urban system planning in Shu city of Kazakhstan is evaluated according to the defined dimensions, which play a key role in determining the population’s living standard, and the indicators of each dimension are compared. The data are obtained mainly through the household questionnaire survey, field observations, in depth interviews, and focus group discussion. In total, 832 representative respondents were surveyed with five-point Likert scale questions in this paper. The study used 42 indicators based on six dimensions: environmental, social, cultural, economic, religious/spiritual, and institutional dimensions. The results of this analysis show that the sustainability level of urban system planning in Shu city is at a low level in all six dimensions. The results of the indicator analysis show that the people of this region are generally not satisfied with the solution of some environmental, social, and economic problems in Shu city. At the same time, residents rated the indicators of institutional stability as better, on the contrary, they rated cultural and religious/spiritual indicators relatively high. As a result, we initially asserted that the sustainability of the urban system planning in Shu city is not satisfactory considering the existing possibilities. To eliminate this shortcoming, the authorities responsible for planning the urban system should jointly develop a project policy for sustainable development with all interested parties.

Implications of peri-urban land reform programs on urban land markets: a case study of Harare, Zimbabwe

Zimbabwe implemented the Fast-Track Land Reform Program (FTLRP) in the year 2000. This program has had far-reaching implications on urban development, especially on urban land markets in cities and towns. This paper highlights the implications of the land reform program on urban land markets, using Harare as a case study. The paper is based on document review (policy, academic and development literature) and interviews with key informants with experience and knowledge of the land reform and its associated implications on urban land markets. Our analysis demonstrates that the land reform process in peri-urban spaces was complex and largely driven by political interests. The land reform process distorted the urban planning processes, leading to disparities in the land markets. Such disparities include informal and uncontrolled processes of accessing land and, ultimately, rapid development of informal settlements in the city. Political elites and land barons took advantage of the land reform program extorting money from desperate home-seekers. We conclude that the distortion of urban land markets by politically driven land reform processes negatively affects sustainable urban development. Overall, the paper makes a valuable contribution to the growing literature on land reforms and peri-urban development in Africa, demonstrating the complex and multidimensional implications of land reform programs on peri-urban land markets. Based on the study findings, the paper provides a set of policy recommendations aimed at improving the effectiveness and equity of land reform programs in African peri-urban areas.
