This study uses the case of Nuremberg to investigate the regional pattern of renewal in urban residential areas on a middle scale from the standpoint of physical and social structure in Ger-many since the 1970s when the supply of dwellings surpassed demand and many urban renewal projects have been carried out. I study the regional pattern of social structure, social housing units, urban renewal projects and the number of construction in the urban area. The regional pattern of renewal is divided into two types in the urban area located within a radius of 3 km from the city center and in the southern area.

Social housing customization in Brazil refers to the current processes of development and evolution of government-funded neighborhoods for the lowest-income population. The mass production of small housing units that do not satisfy family needs instigates a self-design and self-construction process post-occupancy to customize the units. Ultimately, these changes to the units bring unintended negative consequences for the families and the city. In this context, mass customization is seen as an alternative to address some of the problems related to unit design.

The article analyzes the processes of suburbanization and transformation of the spatial structure of the city of Ulan-Ude. Modern trends in the growth of Western and historical factors of development, due to socio-economic and historical factors of development. In the 1990s-2000s, because of the decline in agriculture and, as a result, the lack of jobs, the rural population began to migrate massively to the Buryat Republic’s capital. However, the prices for houses and apartments in the city center were unbearable for many migrants, so the purchase of land plots and the construction of houses were affordable for many. The estrangement of agricultural lands and their inclusion in residential areas allowed the city of Ulan-Ude and suburban areas to somewhat expand the territory of settlements and create a huge number of GNPP (gardeners non-profit partnership) and DNPP (dacha non-profit partnership). The city and suburban areas were not ready for such a flow and were not able to provide the newly arrived migrants with social, road transport and communal infrastructure. As a result, the city was surrounded by a suburbia almost devoid of any infrastructure. There are some elements of false urbanization or squatter area, which is a type of urbanization in which the urban population rapid growth is not accompanied by a commensurate increase in urban functions. In recent years, the growth rate of suburban settlements has decreased, mainly due to mortgages, which have become more affordable for the population and the growth of multi-storey construction. In addition, the village is slowly depleting the human resources that feed the city and the suburbs. In other words, those who wanted to move to the city have already moved

Solar energy constitutes one of the most effective alternative energy sources for combating climate change. However, the solar potential in a city can vary depending on the urban morphology. The purpose of this paper is to perform a directional statistical analysis of the distribution of the monthly solar potential of rooftops in the city of Cáceres, Spain, in relation to the orientations and slopes of the rooftops. Two residential areas, one in the city center and one on the outskirts of the city, and an industrial zone, all of which exhibit different urban morphologies, have been evaluated. Statistics have been assessed in consideration of the orientation and slope values of the rooftops as circular data, and the radiation values as linear data. The three dissimilar urban morphologies result in different solar potential values, and the monthly disaggregation of the data enables the ability to detect the differences existing in the solar potential between each zone, during each month. The proposed analysis could also be extrapolated to urban planning for the design of more sustainable cities to face the challenges associated with climate change.

The present study aims to grasp the car ownership characteristics of households in the sub-urban area in Makassar City, Indonesia. The study considers some exogenous characteristics of the households, such house types, family size, income, motorcycle ownership, trip number, and worker number. To construct the relationship between those characteristics and the car ownership, we applied the multinomial logit model approach. This study surveyed seven residential areas in the sub-urban area of the city. The survey conducted an interviewing method using a questionnaire sheet. The survey respondents as representative of the households, which selected randomly from the residential areas. The results show that the goodness of fit of the car ownership model is acceptable enough. Further, all of the exogenous variables significantly influence the households in car ownership. We expected that the results provide a basis for further studies such time valuation of car riders, mode choice model of the households, etc.

Existence of social groups with different socio-economic status is a common character in a city and makes cities to form residentially varied areas within the city which is generally termed as ‘residential differentiation’. Since residential differentiation sometimes becomes a critical issue to be addressed it should be understood as much as possible before planning and organizing the urban space in optimal manner. This study attempts to investigate spatial expression of occupational structure of Kandy city, Sri Lanka. Attention is given for identifying, measuring and mapping the existing location pattern of occupational groups over the urban space of Kandy city. Occupation data in Kandy city collected from national census of population and housing in 2001 were used and Location Quotient technique (LQ) was employed to analyze the data.Results evidently revealed that ‘occupation’ is influential to form a distinct location pattern in the city space. Basic pattern of location of occupation groups identifiable is that higher ranking occupation groups are concentrated in peripheral areas while lower ranking occupation groups are located in city canter areas or proximity areas to the city Center. This has made some particular areas to be specialized for some occupation groups. Working class or labourer category which has the highest proportion is mostly limited to city center and adjoining areas where commercial and other services are dominated. These areas are highly commercial and mix residential areas in the city and are very valuable lands that can be used for the better economic use establishing new projects. This is one of critical issues to be addressed in future development of the city.

Formation and development of the central part of Chernivtsi is a long historical process. The settlement, which emerged in the XIV century, underwent major urban transformations that took place during the XVIII-XX centuries. They became an important period of creation of the renewed structure plan of the city area which is still in operation. The historical city centre has been changing its structure, size, functional organization during a long time. The objective of the research is to study and compare the main parameters and characteristics of the city at certain historical stages by analysing the development of its transport network. The purpose of the article is to review and analyse available cartographic materials and study the street network development in the historical part of the city in the late XVIII - XX centuries. The article highlights the factors that played an important role in the formation and development of Chernivtsi city centre, in particular, strengthening and expansion of economic ties. According to the findings, discovery of new trade routes became a decisive factor that influenced the development of Chernivtsi, determined the city structure and directions of the main streets. Other important factors include natural conditions and local terrain, social economic and administrative impact. Studies have shown that the historical centre of Chernivtsi evolved according to the existing structure plan. Analysis of cartographic materials and historical sources allows to characterize the basic principles of urban development. Expansion of the street network and squares, as well as trends in the planning of residential areas provide an opportunity to assess their nature, scale and size. Topographical maps enabled us to devise comparative schemes of urban development and evolution of city boundaries throughout the studied period. The city center moved gradually to new areas in the south-western direction. This feature of the city development provides important materials for urban study. This work can be primarily aimed at studying the urban planning structure, defense lines, public spaces, etc. The city developed in an extensive way, pushing the boundaries of the city center, creating new parallel urban complexes with new central squares. The most difficult task for scientists today is to localize these boundaries for different stages. The next difficult task is to find out old defense systems existed in the different parts of the city in the past. A completely unresolved question is how defense complexes influenced the development of the planning structure. The study allowed to highlight the prerequisites for major urban transformations in the historical part of Chernivtsi in the XVIII - XX centuries.

Jakarta, as the center of government, trading, business, and industry becomes the main destination for many migrants to find jobs. This results in the massive population increase in Jakarta every year while the urban area availability has contrast proportion with the needs of housing area. The limited urban area, as well as the increase of land value, is not possible to build new housing area in the city center. The solution of this problem is rejuvenation of the buildings that have already existed. In this case, the writers carry the rejuvenation case of the vertical housing in Kebon Kacang XI that is close to the age limit of the building and has looked slum thus created visibility gap between the vertical housing and the other housing areas and could get the gentrification results. Besides, Kebon Kacang XI vertical housing is located in the center of Jakarta and has increasing BCR so that it is able to maximize the unit of building capacity to fulfill the needs of affordable houses in the city. The aims of this paper are to find out and to compare three different forms of rejuvenation as the solution of housing area provision for the low-income people in the city center through revitalization, rehabilitation, and redevelopment approach.

ABSTRACTCities are spatial plans on the surface (land) with administrative boundaries that have been determined where there is concentration of the population in it along with various economic, social and political activities. The city is a residential spatial structure with a large number of people on limited urban land, which is generally non-agrarian. The development of the city does not always have a positive impact, but it has a negative impact including the emergence of slum areas around the city center. Around the city center there are various centers of activity including tourism, health, education and trade as well as services in the city, provincial and national levels. The five activities are developing quite rapidly which has resulted in the development of residential areas around the city center and the poor development of slums in these locationsThe purpose of this study is to analyze the factors that influence the development of slums. The research location is in the city of Bukittinggi, West Sumatra Province. This study uses primary data by distributing questionnaires to households throughout the City of Bukittinggi. The analysis used is logistic regression analysis. The results showed the factors that influence the development of slums including the Quality of Dwelling, Building Density, Education and Road Accessibility. These influencing factors can be used as a reference for alleviating slums in Bukittinggi City.Keywords: cities, households, slum areas. ABSTRAKKota merupakan suatu tempat pemusatan berbagai kegiatan manusia baik dari kegiatan sosial, kegiatan ekonomi, maupun kegiatan politik dimana berkonsentrasi pada satu tata ruang di atas permuakaan (darat) yang memiliki batas-batas wilayah administrasi yang sudah ditetapkan. Kota merupakan suatu tata ruang permukiman berpenduduk dengan jumlah yang banyak di atas lahan perkotaan yang terbatas, yang pada umumnya bersifat non agraris. Perkembangan kota tidak selalu menimbulkan dampak positif, namun memiliki dampak negatif diantaranya munculnya kawasan permukiman kumuh di sekitar pusat kota. Di sekitar pusat kota memiliki berbagai pusat  kegiatan diantaranya pariwisata, kesehatan, pendidikan dan perdagangan serta jasa baik di lingkup kota, provinsi maupun nasional. Kelima kegiatan tersebut berkembang dengan cukup pesat yang mengakibatkan berkembang kawasan permukiman di sekitar pusat kota dan buruknya berkembang permukiman kumuh di lokasi tersebut. Tujuan dari penelitian ini adalah untuk menganalisis faktor-faktor yang mempengaruhi perkembangan permukiman kumuh. Lokasi penelitian berada di Kota Bukittinggi Provinsi Sumatera Barat. Penelitian ini menggunakan data primer dengan menyebarkan kuesioner ke rumah tangga se-Kota Bukittinggi. Analisis yang digunakan adalah analisis regresi logistik.

The main objective of this work is to investigate the temporal variation of PM10 concentrations within the urban area of Athens during the years 2001-2015. For this purpose, the time series of the particulate matter with aerodynamic diameter less than 10μm (PM10) is recorded for a 15-year period (2001-2015) in two different monitoring stations located in the urban area of Athens. The results show a totally different behavior of PM10 concentrations between the Athens city center and the suburban areas. It seems that in the city center the main sources of PM10 are traffic and heating systems especially during the cold period of the year. Furthermore, in the city center a significant seasonal variation was found with high concentrations during the cold period of the year and lower concentrations during the warm period of the year. Moreover, it was found that during the weekends, there is a decrease in PM10 concentrations probably due to the fact that majority of people do not use their vehicles. Finally, for both locations a significant temporal decreasing trend of the mean annual PM10 concentrations was found which indicates that during the last years, there have been improvements towards a better air quality.

This paper presents the calibration of the most commonly used Volume Delay Functions (VDF): BPR, Conical, Akcelik and Modified Davidson, for an urban area populated by over 1 million inhabitants, the city of Thessaloniki in Greece. The estimation of the unknown coefficients was carried out for a typical freeway, the ring road of the city, and selected arterial and collected roads of the city center, through recent data of hourly observed vehicle speeds and volumes obtained from video recordings and loop detectors. The BPR function yielded the highest accuracy across all the examined road sections and was characterized as the most suitable to simulate and interpret the existing traffic conditions. The estimated coefficients differed significantly from the values proposed in the pertinent literature, which highlights the importance of using locally derived data for the calibration of the VDFs.
