Doctoral Thesis Agro Food System transitions? Exploring alternative Agro Food Initiatives in Izmir, Turkey(Izmir Institute of Technology, 2016-07) Karakaya, Emel; Özatağan, GüldemThis dissertation investigates emerging Alternative Agro Food Systems (AAFSs) in Turkey and does so by focusing on three niche initiatives in İzmir. Building on Regime Theory and the Multi-Level Perspective, it views these initiatives as strategic niches and explores their development processes by documenting their socio-technical practices. Thus, this thesis fulfills the understanding of newly emerging alternatives and their transformation in Turkey with regard to their development processes in İzmir. Through exploratory qualitative multiple case study, this dissertation provided a meso-level investigation, documentation of the agro food system and micro-level investigation of Alternative Agro Food Initiatives in Turkey. A micro-level exploration is undertaken by three niche initiatives in İzmir; (a) producer initiated Alternative Agro Food Niche- Gödence Cooperative, (b) consumer initiated Alternative Agro Food Niche- BİTOT and (c) producer-consumer collaborated Alternative Agro Food Niche-Foça Earth Market. Case studies, which are explored in İzmir, have provided a city-level investigation through examination of role of İzmir in the emergence and development of alternative agro food niches. Case studies reveal characteristics and development processes of alternative food initiatives. Gödence revealed a niche that shows a degree of compatibility with the incumbent regime. This compatibility blunted the innovative capacity of the niche due to several structural reasons and path-dependencies. Stabilizing path-dependencies created tendencies which restrain the diffusion of socio-technical practices. On the other hand, BİTOT and Foça Earth Market formed new niches. The creativity, talent to widen voluntarism and existing networks of Buğday Association provides BİTOT a web of volunteers to create, design and apply socio-technical practices. Foça Earth Market’s unique innovation capacity is lying under its artifice to use incumbent regime institutions to create alternative socio-technical practices. The flexibility in the Foça Niche to motivate actors including those from mainstream regime has contributed to the innovative capacity of the initiative.Doctoral Thesis Analysis of the interaction between theory and practice in urban planning: Understanding Izmir experience(Izmir Institute of Technology, 2002) Kaya, Nursen; Özdemir, SemahatUrban planning, as one of the factors in shaping the urban structure, aims to help to increase the quality of life both through making the necessary spatial arrangements and through development of the urban policies. However the interventions brought through this field of study and action have always been under discussion in terms of the or success of this intervention. Accordingly one of the most ongoing discussions in planning literature covers the issues related to the theory and practice interaction with the aim to see the accordance or disaccordance between planned action and the real world of action and to help to clarify the need or success of this intervention. This thesis study is carried out with the aim to understand the interaction between theory and practice in urban planning. It aims to analyze whether the theory of planning guides to the practice of planning and whether the practice of planning shapes the urban structure. In other words it attempts to clarify the role of theory on practice of planning and the impacts of planning practice on urban structure. This study is formed of two main parts as the theoretical frame and the case study. In the first part the study presented the framework of planning theory and a short review of major theoretical approaches stated in planning literature. In the second part the study presented planning experiences of the city of İzmir through carrying out an analysis of planning practices in terms of theoretical background and implementation of planning decisions. The research method followed for carrying out of the study is mainly based on literature search, İzmir Metropolitan Municipality archives search, Yeni Asır newspaper search and on-site observations. This study found out that planning practices of İzmir had been generally guided by various theoretical approaches and these practices had performed many impacts on urban structure of İzmir. However it can not be claimed that the practice had been successfully guided by the theory or the practice had been successful to shape urban structure. Keywords: Planning Theory, Planning Practice, Theoretical Approaches, Planning in Turkey, Planning in İzmir, Urban Structure of İzmir, Prost, Danger, Le Corbusier, Aru, Bodmer.Doctoral Thesis Application of exergy analysis method to energy efficient building block design(Izmir Institute of Technology, 2014-03) Mert, Yelda; Saygın, NicelThis dissertation introduces the exergy analysis method into urban planning field in order to find out the amount of energy that can be conserved in a building block when energy efficient design is applied. Two hypotheses are developed here: 1. Exergy analysis is a suitable tool for the built environment, and 2. Energy efficient design parameters provide energy saving in the built environment. A case study approach is undertaken in order to test the hypotheses stated above. To do this, first, the energy efficient design parameters have been derived from the literature and design alternatives are developed accordingly; second, data has been gathered from the case area for the exergy calculations; third, exergy analysis of existing building blocks and proposed design alternatives are carried out, and finally, the amount of decrease in the exergy loss due to energy efficient design is found out. The findings in this study show that the exergy efficiency of the existing building blocks is nearly 2 %, while the proposed design alternatives are nearly 10-11 %. The overall exergy loads of the alternative plans are found as 166.3W, 225.1W, 142.5W, 137.8W and 184.8W respectively for winter and 105.4W, 140.0W, 89.9W, 86.3W and 125.3W respectively for summer on a housing unit basis. These results are much better when compared to the existing situation per housing unit which is 1079W (winter) and 1173W (summer). The best alternative energy efficient planning and design brings 1631 W (winter) and 2810W (summer) of exergy saving that corresponds to 799 TL/year and 978 kg/year reduction in CO2 greenhouse gases emission per housing unit. This data shows that the expected results and are in harmony with the literature. As a result, the suitability and importance of the exergy analysis on the built environment is proved by revealing the energy conservation and sustainable use of energy through using energy efficient design parameters.Doctoral Thesis Assessing subjective quality of urban life at neighborhood scale(Izmir Institute of Technology, 2014) Velibeyoğlu, Hasibe; Arkon, CemalThe subjective nature of quality of urban life (QoUL) has not been adequately addressed in the planning literature. Major aims of this study are to elaborate the notion of subjective QoUL as meaningful and measurable quality categories in terms of urban planning policy and to give additional information to urban policy makers and planners about needs of different socio-economic groups and their satisfaction with urban living. This study explores the concept of QoUL defined as the performance level of urban life towards the needs and expectations of residents. The study uses Maslow’s theory of human needs as a starting point to investigate subjective dimensions of OoUL. It explores this concept in a neighborhood scale as subjective evaluations gain significance while the geographic scale getting smaller. To address the significance and priority of subjective dimensions and to re-define satisfactory character of urban living Kano’s Model is selected as an major analysis tool. Using Kano’s Model to understand and prioritize the impacts of urban needs over life satisfaction has become possible. This analysis method creates a basis of strategic action while transforming subjective perception to the understandable categories of quality. Given the limited public resources, policy makers need to find the most effective way of distributing them in line with the needs and the priorities of people. This can be achieved by using the results of the related research as input in the decision making processes.Doctoral Thesis Conflicts in the planning processes of Locally Unwanted Land Uses (LULUs): Case studies in Izmir(Izmir Institute of Technology, 2014-07) Atay Kaya, İlgi; Kaya Erol, NursenLand use planning is both a technical and a political process in which many different groups with multiple interests are affected by planning decisions. While every land use planning decision has a potential of creating conflicts, Locally Unwanted Land Uses (LULUs) are the most conflict facing subjects in urban land use planning because of their negative externalities such as health effects, economic costs and harms to environment. This thesis aims to find out the reasons of and solutions for the conflicts in the planning processes of LULUs. The thesis focuses on conflicts about three LULU types including solid waste facilities, fisheries and quarries in zmir, Turkey. Qualitative research design is used with techniques including document analyses, media search and in-depth interviews. In the case studies, the conflicts are analyzed with a proposed analysis method including issues for understanding and resolving conflicts. These issues are used to discuss characteristics and reasons of conflicts and existing and proposed conflict resolution methods. It is found that the reasons of conflicts are not only the negative effects of LULUs such as odor, pollution and noise but also procedural deficiencies such as lack of knowledge and lack of trust. The findings in case studies supported the theoretical works concerning limitations for the success of participatory processes seeking for consensus. Conflict resolution attempts including symbolic benefits rather than considering exact interests of local people should be rethought.Doctoral Thesis A critial evaluation on the concept of justice in planning process-judicial oversight: The Balçova and Narlıdere cases(Izmir Institute of Technology, 2005) Şenol, Pervin; Arkon, CemalThis thesis aims at scrutinizing what is meant by the concept of justice and the ways the concept is being referred to in urban planning practice in Turkey. Aimed as such, the due analysis involves examination of how the concept is taken into consideration and defined by different actors taking part in urban planning process of our country. The basic data underlying the considerations based on not only the conceptual discussions, but also the planning practice will comprise different demands concerning the urban space and the cases of lawsuit under control of adjudication as reflections of these demands upon the process of planning. The questions to which this study based on .justice. in the urban system and the planning discipline are to be answered can be listed as follows: Which concepts, which ideals, which discourses and methods are used during the process of distribution mechanism in the economic realm, law system and judicial process? How are the basic concepts of justice, namely equality, interest, right and liberty used in defining and encountering the urban social needs in these processes? Do the achieved results involve any targeted ends that can be called as just? In order to elucidate the understanding and demands of justice, conceptual information pertaining to the concept of justice is required. For this reason, study focuses on theories of justice and elaborates the fundamental points of concepts, theories and their reflection on the state regulations. Regarding an assessment of the Turkish practice, overall assessments are held as based on cases of lawsuit under control of adjudication. The cases of lawsuit are assumed to represent matters of conflict/dispute and spatial demands of actors regarding the urban space. Accepted as such, the spatial disputes will be elaborated on basis of the matters of case study area in emphasis.Doctoral Thesis Critique of legislation by scientific-technical criteria: toward classification of cultural properties in Turkey(Izmir Institute of Technology, 2007) Marmasan, Önder; İpekoğlu, BaşakThe subject of the study is the contemporary conservation of immovable cultural properties. Eminent charters and conventions from the issue of Venice Charter to the present which show technical and legal quality were examined to determine the changes in time. As the study area physically limited with Turkey, immovable cultural properties that were conserved, investigated at Turkish legal texts and acts in force. Aim of the study is to investigate a systematic approach to fix the immovable cultural properties that show some kind of characteristics and applicable within the conditions and potentials of the country. Samples of immovable cultural properties were selected by examination of local geographical magazines, folkloric researches, experiences and official correspondence in addition to identifications at legal texts. During the study (i) some of the administrative institutions. awareness about the troubles of fixing immovable cultural properties (ii) essence of a systematic way defining immovable cultural properties (iii) presence of considerable number of folkloric research resources that show the relation between traditions and physical environment (iv) conflicts at fixation and registration decisions about identical immovable properties and absence of conservation policy that depends on technical and legal basis (v) absence of a national inventory of immovable cultural properties although there is an insufficient unofficial efforts (vi) a new legal attempt to reorganize the administrative institutions were all observed. The study defined a framework for classification of immovable properties that were left out the official conservation process and generally located at the fringes of settlements or at rural. In this context criteria for classification determined and listed for making investigation of inclusion class for each immovable property. Finally recommendations for reorganization of conservation institutions proposed.Doctoral Thesis Detection of environmental and urban change using remote sensing and GIS(Izmir Institute of Technology, 2007) Tarhan, Çiğdem; Çelik, Hüseyin MuratThis thesis is an example of how land use changes could be detected via high resolution remotely sensed data in GIS environment. In order to perform .change detection. IKONOS satellite images, belonging to 2001 and 2004, have been used. An automated Graphical User Interface (GUI) has been created for detection of environment. Different image enhancement techniques and a fuzzy inference system have been combined in the GUI. The detection results are classified according to some basic levels such as 20, 50 % and 70 %. Additionally, four different change detection algorithms have been applied, which are pixel-based, object based, feature based. These algorithms have been examined according to change detection levels with different image enhancement techniques.In this context, the primary objective of this thesis is to detect environmental changes regularly using RS and GIS in order to obtain up-to-date information about the urban areas.The secondary objective of the thesis is to compare the existing techniques with the newly developed GUI for change detection of environmental changes and to discuss the improvement in the overall results using information obtained with different detection techniques.The hypothesis of this thesis is to develop a new GIS based change detection system. Thus, it would be realized in the GIS environment efficiently and overlaid the results with digitized data in the same environment.Keywords: Remote Sensing, GIS, change detection, urban data, Izmir.Doctoral Thesis Developing a strategic decision- making process for local energy planning and urban land- use evaluations: The case for Balc¸ova geothermal energy(Izmir Institute of Technology, 2009) Kutluca, Ahmet Kıvanç; Özdemir, SemahatThe concept of 'renewable energy' for countries such as Turkey which are classified as poor, in terms of reserving the mentioned fossil energies could be an opportunity for being independent. 'Geothermal Energy' among the renewable energy sources in our country is known as an important type of valid and potential energy sources. Design and land-use are closely linked to the energy efficiency levels for an urban area. The current urban planning practice does not involve an effective landuse-energy evaluation in its 'blueprint' urban plans.The case of Balçova, a district in the Izmir Metropolitan area, is used conformingly for evaluating the proposed master plan and the 'geothermal energy district heating system' use for the concern district.The examination of the existing development plan with an .energy sensitive.point of view, determination of the questioning criteria's, and the evaluation of alternative compromises that can be done on planning principles, form the originality of thesis. The construction is completed by the integration of these policy-planproject scaled approaches during this evaluation.According to the thesis main idea, the proposed energy sensitive land-use planning method can be an effective tool for planners as simulation media in GIS programs using, to evaluate efficiency levels for different plan proposals, letting to know how much energy saving causes how much deviation from the other planning ideals.In the extent of the thesis, an alternative energy sensitive (integrated) land-use planning approach is aimed in the example of 'geothermal energy district heating system' by using development tools of land-use planning, planning brief and plans on .the increase in energy efficiency in urban settlement. approach.Doctoral Thesis Differences in the uses and needs of neighborhood parks: A case study about female park users in Balçova (Izmir, Turkey)(İzmir Institute of Technology, 2016-07) Kaştaş Uzun, İpek; Şenol, FatmaNeighborhood parks as important public open green spaces are supposed to provide certain opportunities of improving physical and mental health, socializing with others and developing public expression and identity in neighborhoods. However, on the contrary to ideal definitions of public open green spaces as open and accessible to all groups of the society, in real life this “access” is not guaranteed for all, mainly due to unequal distribution of resources. Especially certain groups of the society experience urban inequalities due to unequal distribution of resources. Women is one those groups who experience urban inequalities. The aim of this thesis is to produce a comprehensive research method that adopts a need-based approach to understand underlying causes of different user groups’ park needs and uses by looking at the different experiences of women in neighborhood parks based on their park perceptions as an example. Therefore, I conducted a case study in the neighborhood parks in Balçova, İzmir, Turkey with "mixed method" as a combination of both qualitative and quantitative data collection and analysis methods. I realized detailed observations, questionnaires, structured and un-structured interviews with Balçova residents in neighborhood parks and community houses. As a result, this study contributes to the scientific literature with the produced comprehensive research method, park improvement suggestions that consider the differences in the needs and uses of neighborhood parks and a raised awareness regarding the park needs of women, especially the ones who are bound to neighborhood space with limited social and leisure activity opportunities.Doctoral Thesis The effects of improvement plans on urban transformation process in illegal built up/squatter areas in Turkey: İzmir and Ankara cases(Izmir Institute of Technology, 2008) Eğercioğlu, Yakup; Özdemir, SemahatToday, urbanization problems which have been experienced in the past fifty years in our country have also brought about other deep-rooted problems in other sectors. The migration which started in the 1950s is the major cause of all urban problems. The social and economic problems that arose after migration, later manifested themselves in the physical space; and after the emergence of the first squatter houses a process that later turned into a practice of continuous illegal building construction was to begin. Urban problems have turned into an impasse due to the uncontrolled development and cities spreading hastily towards their peripheries, the changing social structure of cities after migratory waves, continuously mounting spatial problems, lack of policies, an even policies promoting these developments. However, it is stressed by the State Statistics Institute that the speed of population increase will go down significantly in next decades. The decrease in population rate and the focusing of government policies on the transformation of squatter areas give hints for the fact that urban transformation will always be on the agenda in the following years.In this sense, within the scope of this thesis study, especially the transformation processes which formed in the squatter/illegally constructed areas of the post 1980s in Turkey were investigated in detail. In order to present an objective picture of the transformation processes in those areas, two different samples which experienced the same transformation process in the post 1980 period were selected because different transformation processes emerged in different squatter areas where the same improvement plan was applied. Along with this, as two different work areas, the improvement plans which were applied in the squatter/illegally constructed areas in Ankara-Çankaya and Izmir-Konak municipalities were investigated, and the transformation processes were analyzed and the two different processes were reflected. At the basis of this study lies the need for investigating the urban transformation processes in squatter and illegally constructed areas, which seems especially to be a problem of big towns and metropolitan cities, and also the thought of identifying the problem objectively. This study aims at identifying urban renewal form and how the transformation process has developed, and under what sort of conditions within the present settlement of the Turkish cities, in other words in squatter or illegallyconstructed areas in recent years. In this study, in order to find out under what conditions and in which organizational structure market-based urban transformation processes were realized by individuals and in the leadership of constructors, the squatter/illegally constructed areas in Ankara-Çankaya and İzmir-Konak municipalities, where improvement plans were applied, were comparatively investigated. Key Words: Urban Transformation Processes, Squatter Areas, Improvement Plans, Redevelopment, Holistic Planning, Partnerships, Participations.Doctoral Thesis Evaluating the impact of urban competitive advantages on economic revitalization of deprived inner cities through a case study held in İstanbul(Izmir Institute of Technology, 2008) Yalçıntaş Ağan, Hande; Arkon, CemalThis dissertation assesses the impact of Urban Competitive Advantages in deprived inner city areas in Turkey and strength of the potential for marketability of those advantages, for economic revitalization in the case of Turkey. .The Urban Competitive Advantages Approach., compliant with latest discussions on urban economic regeneration, is a strong economy-based approach focusing on the need for recognition of inherent advantages of distressed inner cities and relies on the development of specific marketing mechanisms to promote those advantages in order to stimulate private inward investment. Accepting true contribution of the approach to urban regeneration, the thesis first examines several projects from abroad to determine key indicators in assessing the competitive capacity of a locality and then, makes use of those indicators in a case study in Istanbul in order to illustrate to what extent the present advantages contribute to stimulation of reinvestment in inner cities given the political uncertainties, economic instability, available financial mechanisms together with legislative and institutional capacities in Turkey. Finally, it is observed that resulting remarks on case study analyses support the main hypothesis of the thesis that .national policy directions and current regulatory, organizational and financial framework for urban regeneration in Turkey can only help finding best economic use of distressed inner city spaces when reformulated in the way they market competitive advantages of concerned spaces.. The dissertation concludes by recommending innovations and reviews through policy directions and necessary mechanisms in legislative, organizational and financial issues for Turkey.Doctoral Thesis Evaluation of creative industry clusters through the ecosystem approach: Investigation of weedding wear sector in Izmir(Izmir Institute of Technology, 2015-07) Mengi, Onur; Velibeyoğlu, KorayThe emergence of new economy has brought the creative industries onto the urban research agenda. Despite the extensive literature on the subject, there is need of a more in-depth approach to investigation the unique formations of creative industry clusters. The aim of this dissertation is to explore the particular organizational and spatial structures of creative industry clusters from the ecosystem perspective. This present study recognizes the fashion industry as a creative industry and the wedding wear sector as its subset. Then, it investigates how the cluster of wedding wear sector operates as an ecosystem in terms of the diversity, interaction, competition and evolution in the case of Mimar Kemalettin Fashion District. The methodology consists of the literature review, preliminary field studies, development of the DICE model which explores the diversity, interaction, competition and evolution of ecosystems in a particular space, pilot study for testing the model, data collection via site visits, DICE survey and additional interviews on site, data processing through descriptive analyses and regression analyses, and conclusions. The findings reveal that the existing cluster is young and emerging. This ecosystem currently self-operates with shortage of diversity in a concentrated spatial structure. The role of geographical proximity and the existing local buzz are substantial on excessive internal interactions. The existing competitive atmosphere is portrayed as a win-lose situation and there is a considerable disinterest towards to collaborations. For evolution, the ecosystem mutually co-evolve with mutation occurred inside the firms. Also, the crossover is found primarily a localized phenomenon.Doctoral Thesis A genetic-fuzzy system modeling of trip distribution(Izmir Institute of Technology, 2010) Kompil, Mert; Çelik, Hüseyin MuratTrip distribution modelling is one of the most active parts of travel demand analysis. In recent years, use of soft computing techniques has introduced effective modelling approaches to the trip distribution problem. Fuzzy Rule-Based System (FRBS) and Genetic Fuzzy Rule-Based System (GFRBS: fuzzy system improved by a knowledge base learning process with genetic algorithms) modelling of trip distribution are two of these new approaches. However, much of the potential of these techniques has not been demonstrated so far. The present study explores the potential capabilities of these approaches in an urban trip distribution problem with some new features. For this purpose, a simple FRBS and a novel GFRBS were designed to model Istanbul intra-city passenger flows. Subsequently, their accuracy, applicability, and generalizability characteristics were evaluated against the well-known gravity and neural networks based trip distribution models. The overall results show that: i) traditional doubly constrained gravity models are still simple and efficient; ii) neural networks may not show expected performance when they are forced to satisfy production-attraction constraints; iii) simply-designed FRBSs, learning from observations and expertise, are both interpretable and efficient in forecasting trip interchanges even if the data is large and noisy; and iv) use of genetic algorithms in fuzzy rule base learning considerably increases modelling performance, although it brings additional computation costs.Doctoral Thesis GIS besed spatial equity mapping and park provision at neighborhood scale: Izmir case(Izmir Institute of Technology, 2019-07) Özkan, Sevim Pelin; Şenol, FatmaDecision making and implementation processes of allocation of neighborhood parks are significant in urban planning. Neighborhood parks contribute to the continuity of biodiversity and improvement of individual/communal physical, social and mental health. Such green public areas in the city are planned under the influence of multi-factors that do not always prioritize these significances and accessibility of these areas for various social groups. As in the case of Izmir City (Turkey), ultimately, there are spatial inequity among neighborhoods in terms of the existence of public green areas. The areas with limited size of neighborhood parks have often high percentages of children, elderly and low-income—that is the social groups that need to get access in walking distance and benefit from these areas. This study conceptualize these areas as ‘park poor’ and the potential user groups as need groups. This study argues that it is possible to develop accessible new green areas in already developed “park-poor” urban areas. Using tools of Geographic Information Systems (GISs) and relying on need-based equity approach, this study presents a GIS based procedure to assess the accessibility to existing park areas and to allocate new neighborhood parks at the neighborhood level in “park-poor” areas of Izmir (Turkey). It contributes to the discussions about the spatial equity mapping and accessibility to areas as part of environmental justice issues. Also, arguing that urban green areas are public resources, this study emphasizes that urban planning policies must re-plan neighborhood parks based on the need-based equity that favors accessibility of neighborhood parks primarily by children, elderly, women and low income groups. Moreover, this study differs greatly from earlier studies about its spatial scale of investigation and use of data. This study suggests park provision procedure in park-poor neighborhoods. To develop these at the neighborhood-level, a set of spatial-statistical analyzes are developed using GISs.Doctoral Thesis The impact of pedestrianization on residential property rental values(Izmir Institute of Technology, 2007) Cömertler, Seval; Kaya Erol, NursenWithin the context of the economic valuation of open space, the aim of this study was to understand the impact of pedestrian ways as a public open space on rental price of residential properties. With this aim, the study also searched suitable variables to determine the factors affecting this impact.The study involved a two stage procedure as theoretical analysis and empirical analysis. In the first stage, fundamental concepts and approaches were evaluated by reviewing related literatures of urban design and environmental economics disciplines.In the second stage, to analyze the impact of pedestrian way attributes on rental price of residential properties, an empirical analysis was carried out by employing Hedonic Price Method (HPM) which is basically a regression analysis estimating the effect of each relevant variable on the price of the asset in question. The analysis was realized with a sample of 140 observations in the case of Forbes Pedestrian Way, which is called as .Sevgi Yolu. (Way of Romance), in İzmir.The study has put forward that pedestrian way as a public open space has a relative measurable economic value like other public open spaces; it impacts the rental price of residential properties. Regression analysis results have shown that, proximity to the pedestrian way and level of perceived quality of pedestrian way are significant determinants of rental prices of the residential properties. Consequently, the approach developed in this study has advanced the knowledge about open space valuation and provided the first evidence -in Turkey as well as in the world wide- of the impacts of pedestrian way on residential property.s rental prices. The case of Forbes Pedestrian Way has shown that pedestrian way is desirable and valuable from a housing-market perspective. This evidence has also supported previous researches reporting open space provides a premium for property prices. Besides, Hedonic Price Method is promising in measuring the impact of pedestrian ways on residential property rental prices. Key words: Economic valuation of open spaces, environmental economics, urban design, Hedonic Price Method, Forbes Pedestrian Way.Doctoral Thesis Influence of urban geometry on public investment cost of urban technical infrastructure:a case study of sewer system in Aydın, Turkey(Izmir Institute of Technology, 2005) Gökçen, Tankut; Serim, Muharrem ErkalThe design and implementation of urban technical infrastructure investments have been largely ignored within the traditional planning processes. This process is generallyperformed, first, by producing urban development plans and only then, by developing the plan for the urban technical infrastructure. While this process runs in Turkey as described above, international practices, including those in the developed countries, does not differ all too much; However, today it is very clear that the process of developing technical plans for the infrastructure, which are subject to unique design principles and criteria and are concealed underground must be handled within the site plan developing process. For the purpose of providing sustainable urban development and efficient use of limited natural resourses, integrating infrastructure considerations into city planning process and providing interrelation between them with the aim of minimizing infrastructure costs for public sector are the main goals of the research. To achieve this goal, the study is comprised of the following sections; evaluation of current city and infrastructure planning and construction process and principles to constitute an interrelation between each other by means of comparative analysis techniques; relationship between urban macro-form and urban technical infrastructure costs with respect to urban land use decision, urban net and gross density; and critical evaluation of sustainable form of urban development .compact city form. and urban technical infrastructure relationship. Finally, as a case study, Aydın (a western mid-sized city of Turkey) development plan has been examined and compared with technical infrastructure costs by means of GIS technologies. Using this method; the new development and construction typology for cities, substantive and procedural contribution to the city planning process has been described to reduce the negative side effects of traditional development process of cities for the future. Eventually, completed comparative analysis indicate that instead of improving both planning process defectiveness, location of urban technical infrastructures in alternative spaces or distinctive urban development pattern (modified hexagonal development pattern) has significant contribution on minimizing public investment cost and achieving sustainable urban development as well.Doctoral Thesis Information technologies and urban sapce acase study on Maslak, İstanbul(Izmir Institute of Technology, 2007) Geçer, Feral; Avar, AdileThe subject of the thesis is to examine the urban transformations that have taken place recently in Istanbul due to the dominant use of information technologies (IT)under the globalization process. Technological developments especially in the Information Technology (IT) and the telecommunications sector, influence cities and urban spaces in social, cultural and physical terms. The study focuses on the impact of IT on urban space transformations and processes in Maslak which has emerged as the new central business district for highly intensive IT user firms via a chronologically based data series.Recently Istanbul is a subject to a new kind of transformation in social,economical and physical structures. There is a new economical system enlarging upon the whole world. The globalized cities, as the capitals of this new economy, form new hinterlands which may not be geographically connected instead, associated via virtual linkages of fiberoptics and satellites of information systems and technologies. As a city strongly influenced by the globalization process which is undeniably armed by IT, Istanbul sticks out in Turkey in the world cities inventory.The problem of the thesis is constituted along the debates between two urban form theories: deconcentration theory and economic restructuring theory. This research examines two fundamental questions. First, which functions that used to be in the city are dispersed from the center and why? Second, which functions prefer urban space and tend to be together creating new kinds of agglomerations in some new places such as Maslak? Indeed, through the findings of the study, it is evidently observed with the presented data that, in the transformation process of Istanbul CBD, there are various factors accompanying the alterations in the urban space other than IT. IT is added to this process as a sidelong factor.Doctoral Thesis Institutional use of information technologies in city planning agencies: implications from Turkish metropolitan municipalities(Izmir Institute of Technology, 2004) Velibeyoğlu, Koray; Süel, AkınThis study argues the pivotal relationship between the computing technology and its organizational context. It focuses on nature of implementation in organizational settings that are becoming increasingly important. A further motivation point for this study is to reveal the different discourses (managerial/political/emotional etc.) in the cycle of implementation. The assumption behind this interest is that IT and other technologies are not value-neutral and these tools have the possibility of shaping the goals and agenda of the planning profession.As a part of methodology of the thesis, a comprehensive literature survey was completed around the theoretical issues that constitutes the framework of IT/IS adoption in organizations with a particular reference to urban planning and management. The statements and research questions were tested in the planning departments of selected metropolitan municipalities (Ankara, Izmir, and Bursa) that are experiencing information technologies and systems in various implementation stages. The research strategy was based on a variety of qualitative approaches, including two different types of closed questionnaire-based surveys and semi-structured/unstructured interviews. To measure the success/failure degree of the planning technologies used in the case study organizations in the 'user' dimension of the study, DeLone and McLean.s (1992) IS Success Model and Heeks'(1999) ITPOSMO model were used.Case study research revealed the current stands of ICT implementation in urban planning departments of local governments. It was also evaluated planning practitioner.s commitment and dependence towards computerized planning tools in working practice. In a more exploratory context, a progressive research agenda for ICT implementation in public planning agencies was developed based on the implications of empirical research and literature-based analysis.Doctoral Thesis Integrating case based reasoning and geographic information systems in a planing support system: Çeşme Peninsula study(Izmir Institute of Technology, 2009) Çınar, Ali Kemal; Serim, Muharrem ErkalUrban and regional planning is experiencing fundamental changes on the use of of computer-based models in planning practice and education. However, with this increased use, .Geographic Information Systems. (GIS) or .Computer Aided Design.(CAD) alone cannot serve all of the needs of planning. Computational approaches should be modified to deal better with the imperatives of contemporary planning by using artificial intelligence techniques in city planning process.The main aim of this study is to develop an integrated .Planning Support System. (PSS) tool for supporting the planning process. In this research, .Case Based Reasoning. (CBR) .an artificial intelligence technique- and .Geographic Information Systems. (GIS) .geographic analysis, data management and visualization techniqueare used as a major PSS tools to build a .Case Based System. (CBS) for knowledge representation on an operational study. Other targets of the research are to discuss the benefits of CBR method in city planning domain and to demonstrate the feasibility and usefulness of this technique in a PSS. .Çeşme Peninsula. case study which applied under the desired methodology is presented as an experimental and operational stage of the thesis.This dissertation tried to find out whether an integrated model which employing CBR&GIS could support human decision making in a city planning task. While the CBS model met many of predefined goals of the thesis, both advantages and limitations have been realized from findings when applied to the complex domain such as city planning.
