summary	Most of the traditional studies on urban morphology are based on aerial views. However, the 2D plane model fails to describe the height information of buildings and the relation of buildings and the urban external space. An urban section is another map of an urban area. Through a series of continuous vertical urban slices, the city texture can be transformed into planar linear information containing height and width information. This paper proposes several indicators to describe a series of urban section slices and uses a three-dimensional coordinate mapping method Sectionmatrix to quantify and analyze the relation between the physical geometrical indicators and urban form from the section perspective. Through the case analysis of multiple residential blocks in Nanjing, China, the results showed that Sectionmatrix is convenient and efficient. Sectionmatrix relates the geometrical properties to the spatial characteristics of urban areas and provides a new way to classify, map and define building typologies. This new classification method reveals the tortuosity and complexity of residential blocks. By bridging the gap between quantity and form, the research also suggests other possible applications of Sectionmatrix as a control instrument and test framework for entire cities planning and design.

summary	The forthcoming popularization of Self-driving Vehicles (SDVs) suggests a significant challenge in urban planning, as it enables new mobility patterns for urban citizens. While manufacturers have been developing visionary scenarios where cars become rentable mobile activity spaces, the impact of SDVs on the urban context is unclear. Through the analysis of the new social and technological functionalities developed by car manufacturers, and the projection of these functions into spatial scenarios of use within urban case study site, this paper explores the potential for the redesign of urban streetscapes to reclaim open spaces for pedestrian experiences and urban culture.

summary	In the modern urbanization process, urban planners create rules to define urban form and composition of blocks which are greatly impacted by the road network. This research paper proposes a "city generator", as an urban design toolkit for urban designers to make prototypes of large new town planning and reimagination of city generation. The generator aims to translate planning regulations into three-dimensional urban form and provide users with efficient and intuitive design iterations. Moreover, our generator emphasizes consistency in generation across scales. From a single block to a district, they can be produced in one operation without losing details. Finally, the generator provides a great degree of freedom for users to manipulate, including three aspects - road generation, density mapping and building form. Because of the flexibility of input parameters, generated models can be a rigid urban grid or an organic pattern, which can highly satisfy urban designer's expectations and imagination.

title	Pandemic, City and Planning: The Importance of Systematizing Covid-19 Data in Fortaleza
source	Gomez, P and Braida, F (eds.), Designing Possibilities - Proceedings of the XXV International Conference of the Ibero-American Society of Digital Graphics (SIGraDi 2021), Online, 8 - 12 November 2021, pp. 291–302
summary	The COVID-19 pandemic generated great changes in world societies, and Brazilian cities felt strongly the effects of the disease in physical and social aspects. Thus, this article seeks to describe a work experience involving COVID-19 data for use in urban planning analyses. Its main methodology is the treatment of data about the pandemic in the city of Fortaleza and georeferencing these to generate urban readings. The work resulted in a shapefile file that could be shared among those who wanted to research how the dissemination of the new coronavirus was influenced by specific urban issues in the city of Fortaleza, in addition to generating learning for the students involved in the process. From this it was possible to observe the importance of discussions both on urban policies and the importance of data in urban planning models adopted in the country in view of the new pandemic situation.

title	COVID-19 and the City: An Analysis of the Correlation between Urban and Social Factors and COVID-19 in Fortaleza, Brazil
source	De Luca, F, Lykouras, I and Wurzer, G (eds.), Proceedings of the 9th eCAADe Regional International Symposium, TalTech, 15 - 16 June 2023, pp. 45–52
summary	The COVID-19 pandemic has been the biggest sanitary crisis humanity has ever faced, the virus has contaminated 662.717.929 people worldwide and killed 6.701.270 people. However, these numbers were not distributed equally at international, national or urban scale. In Fortaleza, Brazil, city studied in this paper, data from 2021 and 2022 epidemiologic reports suggest a contamination pattern that starts in neighborhoods with higher Human Development Index (HDI) and then goes to lower HDI neighborhoods, however, throughout all of this cycle, low HDI neighborhoods tend to have a higher lethality rate. These facts raised the hypothesis that those neighborhoods have specific urban and social factors that affect the capacity to respond and prevent COVID-19. The main objective of this paper is to identify the correlation of some urban and social factors with COVID-19 data. To achieve that, the authors selected seven variables (access to water rate, literacy rate, waste collection rate, population density, access to electric energy rate, sanitation rate and average monthly income) to correlate with four COVID- 19 indicators (total number of cases, total number of deaths, contamination rate and lethality rate). For this, it was chosen to apply Spearman’s correlation coefficient and for the calculation the statistical software Jamovi was used. The results show that the literacy rate, the access to electric energy rate and average monthly income have a positive correlation with the contamination rate, however these same variables have a negative correlation with the lethality rate.

source	Gomez, P and Braida, F (eds.), Designing Possibilities - Proceedings of the XXV International Conference of the Ibero-American Society of Digital Graphics (SIGraDi 2021), Online, 8 - 12 November 2021, pp. 127–145
summary	Re-coding post-war Syria is an ongoing research and data platform, focused on innovation and collecting comprehensive, infrastructural and socioeconomic analytics, synchronization data, by using AI driven to give a more transparent image of innovating a new methodology to regenerate the future of post-war smart cities into advanced and sustainable urban environments in a smarter way (Fig. 1). The pressure to achieve a rapid Post-war smart city without clear strategy and comprehensive analysis of all aspects will cause a particularly catastrophic collapse in the interconnected social structure, services, education and health care system, leaving a long-term impact on the society. This paper presents the current status of the Research & Documentation methodology in the Data Collection phase by the objective investigations conducted through a series of local and international workshops species developed in this research called “Re-Coding“, offering consequent direct ground surveys, statistics and documentation study of the targeted areas, merging professionalism and youth power with local community to detect an open source data used as a tool to re-generate a precarious area towards a new methodology.

title	Human-Computer Interaction for Urban Rules Optimization
source	Abdelmohsen, S, El-Khouly, T, Mallasi, Z and Bennadji, A (eds.), Architecture in the Age of Disruptive Technologies: Transformations and Challenges [9th ASCAAD Conference Proceedings ISBN 978-1-907349-20-1] Cairo (Egypt) [Virtual Conference] 2-4 March 2021, pp. 603-613
summary	Faced with the complexity of manual and intuitive management of urban rules in architectural and urban design, this paper offers a collaborative and digital human-computer approach. It aims to have an Authorized Bounding Volume (ABV) which uses the best target values of urban rules. It is a distributed constraint optimization problem. The ABV Generative Model uses multi-agent systems. It offers an intelligent system of urban morphology able to transform the urban rules, on a given plot, into a morphological delimitation permitted by the planning regulations of a city. The overall functioning of this system is based on two approaches: construction and supervision. The first is conducted entirely by the machine and the second requires the intervention of the designer to collaborate with the machine. The morphological translation of urban rules is sometimes contradictory and may require additional external relevance to urban rules. Designer arbitration assists the artificial intelligence in accomplishing this task and solving the problem. The Human-Computer collaboration is achieved at the appropriate time and relies on the degree of constraint satisfaction with fitness function. The resolution of the distributed constraint optimization problem is not limited to an automatic generation of urban rules, but involves also the production of multiple optimal-ABV conditioned both by urban constraints as well as relevance, chosen by the designer.

title	The design of social and cultural orientated urban tissues through evolutionary processes
source	International Journal of Architectural Computing 2021, Vol. 19 - no. 3, 331–359
summary	The research examines how social and cultural properties can be utilised as an alternative planning scheme to improve urban morphology and enhance the overall experience of individuals within the city. The aim is for these socio-cultural properties to be translated into quantitative data sets that define the morphological characteristics of the urban tissue. Through the use of evolutionary optimisation methods, the process of urban growth is simulated through a series of individuals that adapt and optimise for multiple design criteria. The experiment presented quantifies the social and cultural properties of a superblock within the city of Kyoto to generate an urban tissue that is susceptible to future growth.

title	Affective Cartographies for Smarter Cities
source	Gomez, P and Braida, F (eds.), Designing Possibilities - Proceedings of the XXV International Conference of the Ibero-American Society of Digital Graphics (SIGraDi 2021), Online, 8 - 12 November 2021, pp. 1295–1306
summary	This paper focuses on the study of affective and digital cartographies and on relating them systematically with their design applications. The research is based on the Design Science Research strategy, through the following logical structure: (1) Problem identification; (2) Communication; (3) Definition of the objective of the solution; (4) Artifact design, development and implementation; (5) Demonstration and Evaluation. The results presented correspond to phases (1), (2) and structuring of (3). The categorization was based on the principles: (a) dynamism (dynamic vs. static), (b) responsiveness (immediate vs. non-immediate), (c) implementation domain (hard vs. soft), and (d) affective aspect (quantitative vs. qualitative). This was synthesized in a chart, which was submitted to the analysis of a group of 4 experts from a public urban planning entity, and possible applications of affective cartographies in urban projects were obtained. Those were confronted with reality from the overlapping of the problems listed with the synthesis chart, positioning such cartographies as to their vocations.

summary	The paper aims to analyse the parameters for dimensioning the urban block in the context of the ongoing debate over Rio de Janeiro's new Master Plan (PLC N°44/2021). The analysis focuses on three main points: (1) the definition of the block, (2) the discrepancies found in this regard in the land parcelling system, and (3) the limitations that gated communities impose on the parameterisation of the block. The paper briefly relates the role of the master plan in Brazilian urban policy. Next, it points out the arguments that emerged during the public hearings over the new proposed master plan regarding block sizing. Then, it analyses Rio's urban law framework and the literature regarding the city's road network, cul-de-sac structures and gated communities, supported by the blocks and the streets georeferenced maps available at the Rio's Municipality and the Open Street Maps platform. Finally, it discusses the analysis outcomes with the arguments that emerged during the public hearings regarding block sizing.

title	Future Coastal Cities with Biorock Infrastructure - Alternative Coastal Futures with Biodesign
doi	https://doi.org/10.52842/conf.caadria.2021.1.483

summary	Despite having the potential of being a durable building material, Biorock, a form of calcium carbonate formed by the electro-accumulation of minerals dissolved in seawater, has never been applied on an architectural level due to its slow accretion process. This paper aims to plays out the possible narrative of this slow accruing material process in the incrementally submerged coastline of Jakarta, to empower local marginalized communities to self-construct a new city for habitation using Biorock, especially where building material resources may be limited. Urban cores with basic communal, housing and aquaculture facilities will be established using Biorock as the main building structure, which would be harvested in response to the gradual sea level rise.

title	Technology-Driven Participatory Spatial Design in a Developing World Context: The Case of Istanbul
source	Abdelmohsen, S, El-Khouly, T, Mallasi, Z and Bennadji, A (eds.), Architecture in the Age of Disruptive Technologies: Transformations and Challenges [9th ASCAAD Conference Proceedings ISBN 978-1-907349-20-1] Cairo (Egypt) [Virtual Conference] 2-4 March 2021, pp. 551-567
summary	Nowadays, ICT-based participatory design methods, techniques and tools are increasingly used across the globe. A majority of these are employed in high-income “developed” countries with advanced democratic systems which aim at including citizens; desires, needs, proposals as valuable input in city-making processes. In contrast, in the Global South, only a limited number of ICT-based practices aim to empower the citizens in urban design and planning at higher instances. There is a need for deeper research into how citizens can be involved in urban design in developing countries like Turkey situated in between the Global North and the South. In this context, this research will focus on Istanbul, Turkey as a key case. Different than the developed world context, enabling ICT-based participation in Turkey has a wide range of challenges. Among those are the lack of open and governmental data and transparency, the unwillingness of the policymakers to promote and employ participatory design, top-down approaches are the other weak points of these countries. Responding to these challenges, the aims of this study are: 1) to critically address the weaknesses and requirements of existing urban development practices in developing countries with a focus on Turkey, Istanbul and 2) to discuss the possible potentials of ICT-based participation tools and techniques to involve citizens in city-making processes.

summary	This paper fulfills the dual purpose of developing a systematic methodology for designing new constructions and adding to or revivifying existing buildings in historic neighborhoods and demonstrating an effective pedagogy in regard to historic preservation at the undergraduate level. A previously developed methodology for verifying and analyzing hybridity in architectural design is expanded as a foundation for designing an addition to a historic building in a famous urban context, i.e., a registered historic structure in the museum district of New York City. Shape grammar as a computational design methodology is used to analyze the historic fabric of the urban area and to create a configurable hybrid design that is both compatible with that context and reflective of the needs and design of the contemporary urban setting. The validity of shape grammar as a methodology for designing configurable hybrid constructions in historic neighborhoods and its effectiveness in relation to a teaching focus on historic preservation are considered through an analysis of projects from an upper-undergraduate-level architectural design studio. The students used the shape grammar methodology to analyze and understand historic contexts and features in order to generate new designs for the given context.

title	Development of a Tsunami Evacuation Behavior Simulation System for Selection of Evacuation Sites
doi	https://doi.org/10.52842/conf.caadria.2021.2.499

summary	In this study, a tsunami evacuation simulation system was developed using a game engine and open data to reflect the conditions of a local emergency situation at low cost. Chigasaki City, which is a heavily populated urban area and tourist destination along the coast of Japan, was selected as the target area for this study. A total of 20 simulations were conducted using 20,000 evacuation agents categorized as child, adult, or elderly residents or visitors randomly placed on the road surface in the target area. The simulation results indicate that a 10.60% agent damage rate may occur for a tsunami of height 10 m. In lowland areas where the river flows inland, tsunamis were observed to move up the estuary, trapping agents between the river and the coast. In such inland areas, several areas with no tsunami evacuation buildings were observed. Thus, the low-cost simulations provided by the proposed system can provide necessary support for planning and designating appropriate tsunami evacuation buildings in disaster-prone areas.

title	Landscape Visualization by Integrating Augmented Reality and Drones with Occlusion Handling to Link Real and Virtual Worlds - Towards city digital twin realization
doi	https://doi.org/10.52842/conf.ecaade.2021.2.521
source	Stojakovic, V and Tepavcevic, B (eds.), Towards a new, configurable architecture - Proceedings of the 39th eCAADe Conference - Volume 2, University of Novi Sad, Novi Sad, Serbia, 8-10 September 2021, pp. 521-528
summary	In the field of urban architecture and design, augmented reality (AR)-based landscape visualization is useful for building consensus among stakeholders at the design stage. An integrated AR and drone method can visualize future and past landscapes from an aerial perspective but has to address the problem of occlusion, where a 3D virtual model is displayed in front of the real-world objects. In this study, we propose an AR and drone integrated landscape visualization method to handle occlusion by linking the drone's location information in the real world and the camera in the virtual world. The method uses a 3D model of an existing building, which is part of the city model, to represent the 3D model of the design target as if the target were behind the existing building in the real world. Users can use the perspective of the drone, which flies along a set route, to examine the future landscape with high accuracy, as visualized using AR with occlusion handling.

summary	Smart Growth is a fast-growing urban design and planning movement developed by the United States Environmental Protection Agency (EPA). These regulations control urban morphologies such as building form, position, faÃ§ade configurations, building materials, road configurations, which have an explicit association with the microclimate and outdoor comfort. This paper presents an urban modeling and simulation framework that can represent the urban morphology and its impact on microclimate shaped by Smart Growth. First, we created urban models using custom parametric objects and a building component library in BIM. Then we integrated parametric BIM and multiple performance simulations, including wind analysis, solar accessibility, and energy use. For implementation, a case study was carried out using two Smart Growth regulations in the Kansas City metropolitan area. The paper elaborates on the findings from simulation results, challenges in implementation, and limitations of the proposed framework to manage a large number of regulation variables in simulation.

title	DAttE - Detection of Attic Extensions - Workflow to analyze the potentials of roofs in an urban environment
doi	https://doi.org/10.52842/conf.ecaade.2021.1.375
source	Stojakovic, V and Tepavcevic, B (eds.), Towards a new, configurable architecture - Proceedings of the 39th eCAADe Conference - Volume 1, University of Novi Sad, Novi Sad, Serbia, 8-10 September 2021, pp. 375-384
summary	European cities like Vienna are characterized by strong growth and, as a result, by high demand for living space. Extending the attic is one way of meeting this demand. However, there is a lack of data to know which roofs are already expanded and to what extent. The city is interested in the data in two ways: firstly, in relation to the distribution of potentials (a possible change in population density, for example, has an impact on infrastructure and parking space) and, secondly, in relation to the material composition (city as a material resource). This paper provides a workflow to fill this gap of knowledge. The new methods of detecting attic extensions are described and a case study is given at the end to show workability.

title	Land Use Type Allocation Informed by Urban Energy Performance: A Use Case for a Semantic-Web Approach to Master Planning - A USE CASE FOR A SEMANTIC-WEB APPROACH TO MASTER PLANNING

summary	Cities are growing fast and facing unprecedented challenges as urban populations grow and resources are becoming scarce. A citys master planning involves a series of decision-making processes and requires knowledge from various domains. Urban planners are seeking computational support. We present a use case of land use type or building function allocations informed by urban energy performance as a pilot demonstrator for a semantic-web approach to these challenges. The software used for energy performance assessment was the City Energy Analyst. Using a quarter in downtown Singapore as an example, the results indicated 70% to 80% residential supplemented by other land use types favours efficient use of district cooling systems and photovoltaic panels. Urban planners may use the results to narrow down the search space of land use type ratios for the selected mixed-use area in Singapore. The use case serves as a pilot demonstrator for a broader research scope, the project Cities Knowledge Graph. To support master planning, the project aims to build an extendable plat-form to integrate more datasets and evaluation software for various urban qualities and domains.

summary	Recently, many new studies emerged to apply computer vision (CV) to street view imagery (SVI) dataset to objectively extract the view indices of various streetscape features such as trees to proxy urban scene qualities. However, human perceptions (e.g., imageability) have a subtle relationship to visual elements which cannot be fully captured using view indices. Conversely, subjective measures using survey and interview data explain more human behaviors. However, the effectiveness of integrating subjective measures with SVI dataset has been less discussed. To address this, we integrated crowdsourcing, CV, and machine learning (ML) to subjectively measure four important perceptions suggested by classical urban design theory. We first collected experts’ rating on sample SVIs regarding the four qualities which became the training labels. CV segmentation was applied to SVI samples extracting streetscape view indices as the explanatory variables. We then trained ML models and achieved high accuracy in predicting the scores. We found a strong correlation between predicted complexity score and the density of urban amenities and services Point of Interests (POI), which validates the effectiveness of subjective measures. In addition, to test the generalizability of the proposed framework as well as to inform urban renewal strategies, we compared the measured qualities in Pudong to other five renowned urban cores worldwide. Rather than predicting perceptual scores directly from generic image features using convolution neural network, our approach follows what urban design theory suggested and confirms various streetscape features affecting multi-dimensional human perceptions. Therefore, its result provides more interpretable and actionable implications for policymakers and city planners.

summary	Microclimate is one of the important components of the city environment. Previous researches on public space focused on the influence of spatial forms on user behavior, while ignoring the microclimate elements. This makes it difficult to be authentic of further recreational behavior simulation. The study puts forward a new path to study the influence of microclimate on recreational behavior. Taking the waterfront public space as an example, through the combination of field investigation and microclimate simulation, the influence of wind, temperature, and sunshine environment on residents recreational is explored, and the influence will be merged into the recreational behavior simulation. In the process of behavior simulation, the microclimate environment classification evaluation map is used. The study committed to achieve a higher degree of adaption between behavior simulation results and actual conditions. The study introduced microclimate influence factors on the basis of the influence of urban spatial form and service facility elements on behavior activities in the past. Based on that, we optimize the simulation method of urban public space recreational behavior, and improve the accuracy of space diagnosis through showing the impact of microclimate on the behavior of people in the space more objectively and intuitively.
