A piazza for Pedavena in the Belluno Dolomites: Towards recognition of an urban identity
No full textThe town of Pedavena is situated in the Province of Belluno not far from Venice and its redevelopment of the urban space of the piazza has been a particular subject of reflection by the local authority. The town of Pedavena was studied by a research group from the Department of Civil, Environmental and Architectural Engineering at the University of Padua. Today the urban form of this small provincial Commune is the result of the fragmentary growth of the residential urban fabric that is arranged around a more or less compact central nucleus. The meeting space of the community is presented as a place unresolved in its form, lacking precise and definable limits and crossed by the main transit routes. The streets assume the centrality and significance that has to be given to a piazza as a place to be, stay and live. The planning experience of the research group is a valid example of designing liveable civil place by interpreting the city as a unitary fact where the piazza is a place with a clear and distinct form according to an idea of the city made of interconnected spaces, each one formally different but related in rich meaningful spatial sequences possessing the civil character of the urbs
The System of Floor-area-ratio (FAR) Transfer for Historical District Preservation and Renewal: Guangzhou’s and Taipei’s Experiences in a Comparative Perspective
No full textThe emergence of floor-area-ratio transfer system originated in the USA in the 1960s. As a means of balancing interests and constraints, it was applied to the renewal and preservation of historic urban forms. Taking the practices of Taipei and Guangzhou as examples, this paper analyses the development process and influencing factors of the floor-area-ratio transferred system, compares the differences between Taipei and Guangzhou and draws the following conclusions. In Taiwan, the original intention of introducing the floor-area-ratio transfer is to protect the development rights of owners which have been limited by the protection of historical blocks. The floor-area-ratio transfer in Taiwan is a formalized system and the social groups and interest groups that rely on it have a great influence on the development of the system. Finally, a thriving floor-area-ratio transfer market has formed in Taiwan, involving many market participants. In Guangzhou, the floor-area-ratio transfer is an informal system arrangement that satisfies the financial balance of the developer with protective conditions. It is the transfer between different plots within the same developer. The planning committee system has become an option to compensate for the lack of legal sources

Comparison analysis on typical historic cultural districts with AI machine learning technology – Taking Portuguese and Macao districts as examples
No full textWith the rapid development of technology, artificial intelligence has gone into every field, and its development has been further expanded with machine learning as the core technology. How does this help urban analysis and urban form research? This study aims to introduce a new method for analysing and comparing urban morphological layouts using machine learning technology and to explore the possibility and potential of combining urban morphology analysis with machine learning technology. In this exploratory study, several typical Portuguese cities with historical and cultural characteristics are used as learning samples for comparison. Through the combination of urban morphology theory and machine learning, the urban morphological samples are clipped out from the Portuguese city maps, then morphological features are extracted from the samples, establishing training labels as typical Portuguese urban fabric, lastly compared the result with the typical urban areas of Macao using the YOLOv4 object detection algorithm. Through the research, it is found that Macao in the early stage is more morphologically similar to the city of Evora due to their same privilege; after the early 20th century, influence by contemporary Portuguese engineers and urban development strategy, Macao's urban morphology shows a higher degree of similarity to that of Lisbon
Morphogenesis of urban peripheries in the 20th century: Examples from the French Riviera
No full textIn this paper, we present the first urbanization and the subsequent transformations of the urban fabric in peripheral areas around the cities of the French Riviera, with a focus on the 20th century. More specifically, two urban sectors are analyzed in the cities of Nice and Cagnes-sur-Mer. Cadastral maps, aerial images and urban plans over a century and a half constitute the main inputs of the analysis. These coastal cities represent two paradigmatic contexts for the French Riviera. In Nice, the first urbanization was channeled by different plans of the street network, with different spatial logics in the 19th and in the 20th centuries. In Cagnes-sur-Mer, planning interventions were much more fragmented and sometimes completely absent. The second after-war period constitutes a paradigm shift in the urbanization process. A general scheme of the different phases of the morphogenetic process is proposed to summarize our main finding. It shows that the observed urban forms can result from different evolutionary paths. At the same time, strong path-dependencies characterize the sequence of the morphological processes. Compact city forms can be catalyzed by a planned urban grid, but can also evolve more spontaneously. Planned tree-like structures with built-up plots blocking the dead-ends produce less evolutive residential forms. Topographic constraints and urban pressure linked to accessibility patterns in a context of urban growth are also important factors in explaining the observed processes
Research on the integration path of historicity and life of urban Space – Taking Xuzhou Context Axis as an example
No full textIt is the general requirement of urban renewal and construction in China during the 14th Five-year Plan period to strengthen urban cultural characteristics and improve the quality of urban life. At present, there are some theoretical and methodological contradictions between the enhancement of urban characteristics and the improvement of urban life, and it is necessary to explore and solve the method of the integration of the history and life of urban space. This paper takes Xuzhou ‘cultural axis space’ as an example, by using literature analysis summarized urban historic space, field research summary of the urban living space, finally adopts the method of graphic analysis on the historic elements of urban cultural axis space and life factor integration analysis, In order to solve the integration of cultural heritage and public life in urban renewal.
Through the analysis and research, it is found that the integration path of history and life of urban space can be the overall construction of urban cultural environment, the integration of modern urban life into urban historical places, and the integration of urban cultural elements into urban public life. Through constructing the path of the integration of the history and life of urban space, it provides ideas for the construction of urban characteristic culture and the improvement of urban life in urban renewal
The impact of COVID-19 on the economic resilience and spatial vitality of urban commercial cluster
No full textThe spread of COVID-19 greatly limited physical and economic activities in global cities through increasing fears of
infection and government-driven lockdown measures. Accordingly, shopping activities has moved from conventional markets
to e-commerce significantly. Urban retails have drastically decreased over the years due to competition from these disruptive
influences, yet reaction capacities are known to differ by scale and characteristics. This study aimed to investigate the
characteristics of commercial clusters with high economic resilience during the pandemic. Specifically, the research focused
on how online and in-store sales affected differently to resilience of neighbourhood- and district-level urban commercial
clusters in 2019 and 2020. Using panel vector auto-regressive modelling, the study explored the interrelationship between
online and in-store by districts’ characteristics. For the research, credit card payment data in F&B sector, floating population,
and the number of coronavirus confirmed cases data in Seoul, Korea was used to evaluate the vitality of the commercial clusters.
Findings suggest that neighbourhood-level commercial cluster would be more resilient and expected to recover in sales more
quickly. This indicates that commercial clusters would be more resilient if had steady populations, low rent loads, and were
able to accommodate online shopping
Measuring the perceptual quality of pedestrian public space in contemporary Chinese cities – Taking Xinjiekou area in Nanjing as an example
No full textOne of the main goals of urban design is to obtain urban space with good perceptual qualities. Among the numerous perceptual qualities, enclosure, human scale, imageability, complexity, transparency, linkage, etc. are most related to the physical features (Ewing, Handy 2009) and many scholars use quantitative methods to measure these qualities. However, when applying these methods to measure these perceptual qualities of pedestrian public space in contemporary Chinese cities, there are problems as follows: first, the existing quantitative grading standards are very diverse and they are difficult to define accurately; second, for indoor pedestrian spaces, some indicators such as enclosure, imageability, etc. need to be re-identified. This paper selects the pedestrian public space in the Xinjiekou area in the center of Nanjing as an example. Based on the existing Nolli map of pedestrian public space (Luo et al. 2021), the enclosure, imageability, complexity, transparency, etc. are measured in a relatively more objective method. Firstly, streetscape photos of typical pedestrian public space (sidewalks, public squares, interior streets, etc.) are taken to a uniform standard. Secondly, street width, building height, number of people, signs, windows, types of elements, etc. in the streetscape are extracted to match enclosure, imageability, complexity, transparency and linkage, etc. Thirdly, the obtained evaluation results are verified by graphical representation and compared with similar studies. The research finally proposes graphical representation of perceptual qualities of pedestrian public space, which will help to optimize the urban design of space
Evolution and transformation processes of urban form: Urban tissues in Thessaloniki, Greece
No full textThis ongoing study aims at the articulation and documentation of a morphological codification of urban tissues in Greek cities. The aims of the paper are, firstly, to analyze the dynamic processes of production, evolution and transformation of urban form and, secondly, to investigate physical and lived urban fabrics. The paper proposes an integrated methodology of morphological analysis on macro-, intermediate and micro scale which is applied to two representative areas in the historic city of Thessaloniki. Several approaches from different morphological perspectives (historico-geographical, process-typological and relational-material) are employed in each level of analysis. The proposed method of inquiry could be used in urban analysis in two ways: for urban investigations of urban form and as a tool for preparing urban design projects and interventions
