Morphological regionalization for the urban renovation agenda in Daegu, South Korea
No full textFollowing the maturation of Korean cities, urban renovation has become the primary concern of urban policies. Large wholesale redevelopments continue to address decay from a purely physical point of view. In contrast, new area-based urban regeneration projects propose a more delicate and holistic approach to addressing urban decline. The designation of redevelopment or regeneration project areas is not based on the presence of specific urban forms but primarily on technical and economic prospects. As a result, the urban tissue is increasingly losing its structure and coherence. To better connect urban renovation with urban form, it is necessary to identify the various urban fabrics composing large cities such as Daegu. This research executed a large-scale morphological regionalization analysis for the central Daegu city area, based on analysing and evaluating mapping results based on two mapping methods: mixed morphogenetic mapping and morphogenetic mapping. The research results unveil that the urban renovation processes in Daegu lead to the overall consolidation of large apartment complex areas. In contrast, the fine grain urban fabrics that still cover the largest share of the urbanized area are increasingly fragmented. The proposed regionalization is the base for new urban renovation strategy propositions
The paradox of empty apartments and huge daily commuting in Ljubljana: Failures of the urban management
No full textLjubljana as the capital city of Slovenia counts among smaller European capitals. With its population around 300.000 it yet represents a myriad of urban landscapes. The break-up of Yugoslavia radically changed the city population. Suburbanisation and deurbanisation resulted in the degrading city centre where already low-income population resided. Denationalization process shook the real estate market pushing thousands of users of ‘social flats’ into rent of newly formed quasi elite which participated in privatisation of public apartments. High rents drove the residents out and allowed for rebuilding or construction of villa-blocks. These reappropriations had a massive effect primarily on the loss of one sixth of urban population by 2000 and 25,000 uninhabited homes in the city centre. It is hypothesised that the cartel networks and the administrative apparatus use the urban planning as a tool of raising prices in order to gain more affluent population. We concluded that this idea failed. Most of the population live in their own apartments, while rented premises are settled mainly by lower income population with a high share of immigrants. The ecological and economic problem of daily commuters could be solved with an active urban policy of using the huge assets of empty apartments

Morphological Investigation of the Urban Form of Qom (Iran) at the Micro-scale: Spatial Distribution of Streets and Activities
No full textStreets function as the interaction space for two systems of movement and activity. Street layout has influence on both distribution pattern of commercial/service (CS) activities and motorized/pedestrian traffic pattern and vice versa. Qom, a city located in central Iran with a long history of civilization, is characterised by a diverse typology of urban form and accordingly, different kinds of movement-activity patterns in the historic, middle and peripheral areas as the result of morphological, economic and social drivers. To take a step towards recognizing the patterns, this paper aims at rigorously explaining the relationship between the structural features of street layout and CS activity presence in Qom at the micro-scale, i.e. street segments, of the centralised zones through adopting a quantitative approach.
After identifying ten morphologically-homogenous high-centralised superblocks – called local morphological zones (LMZs) –regarding street network centrality index of local closeness (LCNC) using Multiple Centrality Assessment (MCA), thedistribution of layout/activity elements alongside the street segments (weighted by LCNC) are investigated using Lorenz curve.Then, the distribution density datasets of layout/activity elements are modelled using Kernel Density Estimation (KDE) andanalysed by raster comparison techniques. The findings show that the linear distribution of the CS activities alongside the streetnetwork shows more relationship with LCNC rather than the street nodes. Concerning the areal distribution, the highest spatialcorrelation is found between the street nodes, i.e. three-ways and dead-ends and street segments (weighted by LCNC);furthermore, regarding street pattern, a typical historic fabric of Qom is a high-centralised area characterised by high proportionof three-ways and dead-ends, but, by low proportion of four-ways. The results are applicable in achieving the goals ofcommunity planning

On Parameters of Migration in PEA Computing
No full textMetaheuristics, such as evolutionary algorithms have been proven to be
(also theoretically, see works of Vose [1]) universal optimization methods.
Skolicki and DeJong [2] researched impact of migration intervals on island
models. In this article, we explore different migration intervals and amounts
of migrating indyviduals, complementing Skolicki and DeJong’s research.
In our experiments we use different ways of selecting migrants and pave the
way for further research, e.g. involving different topologies and neighborhoods.
Besides sketching out the background and presenting the idea of the
algorithm we show the experimental results and discuss them in detail
Human-centered urban design analytics integrating data-informed and evidence-based approaches: A micro-renewal case in Shanghai
No full textThis study proposes an analytical approach for quantitatively evaluating the human-scale street quality and providing precise design interventions, which usually depended on expert subjective experience and intuition. With the help of multi-sourced urban data and wearable biosensors, both data-informed and evidence-based approaches have been integrated to achieve the measuring of spatial activities and space perceptions. For the dimension of spatial activities, Location-based Services (LBS) data was applied to construct a target user portrait, and Unmanned Aerial Vehicle (UAV) images were applied to efficiently record spatial behaviour. For the dimension of space perception, a series of biosensor devices, including ProComp Infiniti Encoder, E4 Wristband and Eye-tracker were applied to collect data of skin conductance (SC), electromyography (EMG), electrodermal activity (EDA) and eye focus. A road from a Shanghai new town was selected for case study, which was initially built around 1990s and now requires micro-scale renewal. It is a useful representative for many Chinese new towns. By evaluating these key dimensions precisely, this approach could act as an efficient method for site analysis and propose appropriate design interventions. In short, this study contributes to the development of human-cantered urban design by providing a new perspective integrating the large and small data
